## About



Dockerfile to build a [GitLab Enterprise Edition](https://about.gitlab.com/) image for the [Docker](https://www.docker.com/products/docker-engine) opensource container platform.



GitLab EE is set up in the Docker image using the [install from source](https://gitlab.com/gitlab-org/gitlab-ee/blob/master/doc/install/installation.md) method as documented in the the official GitLab documentation.



This Container uses a [customized Alpine Linux base](https://hub.docker.com/r/tiredofit/alpine) which includes [s6 overlay](https://github.com/just-containers/s6-overlay) enabled for PID 1 Init capabilities, [zabbix-agent](https://zabbix.org) based on 3.4 Packages for individual container monitoring, Cron also installed along with other tools (bash,curl, less, logrotate, nano, vim) for easier management. It also supports sending to external SMTP servers..



For other methods to install GitLab please refer to the [Official GitLab Installation Guide](https://about.gitlab.com/installation/) which includes a [GitLab image for Docker](https://gitlab.com/gitlab-org/gitlab-ee/tree/master/docker).



# Issues



Docker is a relatively new project and is active being developed and tested by a thriving community of developers and testers and every release of docker features many enhancements and bugfixes.



Given the nature of the development and release cycle it is very important that you have the latest version of docker installed because any issue that you encounter might have already been fixed with a newer docker release.



Install the most recent version of the Docker Engine for your platform using the [official Docker releases](http://docs.docker.com/engine/installation/), which can also be installed using:



```bash

wget -qO- https://get.docker.com/ | sh

```



Fedora and RHEL/CentOS users should try disabling selinux with `setenforce 0` and check if resolves the issue. If it does than there is not much that I can help you with. You can either stick with selinux disabled (not recommended by redhat) or switch to using ubuntu.



You may also set `DEBUG=true` to enable debugging of the entrypoint script, which could help you pin point any configuration issues.



If using the latest docker version and/or disabling selinux does not fix the issue then please file a issue request on the [issues](https://github.com/tiredofit/docker-gitlab/issues) page.



In your issue report please make sure you provide the following information:



- The host distribution and release version.

- Output of the `docker version` command

- Output of the `docker info` command

- The `docker run` command you used to run the image (mask out the sensitive bits).



## Prerequisites and Assumptions



Your docker host needs to have 1GB or more of available RAM to run GitLab. Please refer to the GitLab [hardware requirements](https://github.com/gitlabhq/gitlabhq/blob/master/doc/install/requirements.md#hardware-requirements) documentation for additional information.



## Installation



Automated builds of the image are available on [Docker hub](https://hub.docker.com/r/tiredofit/gitlab-ee)



```bash

docker pull docker.io/tiredofdit/gitlab-ee:latest

```

You can also pull the `latest` tag which is built from the repository *HEAD*



```bash

docker pull docker.io/tiredofdit/gitlab-ee:latest

```



Alternatively you can build the image locally.



```bash

docker build -t tiredofit/gitlab-ee

```



### Quick Start



The quickest way to get started is using [docker-compose](https://docs.docker.com/compose/).



```bash

wget https://raw.githubusercontent.com/tiredofit/gitlab-ee/master/examples/docker-compose.yml

```



Generate random strings that are at least `64` characters long for each of `GITLAB_SECRETS_OTP_KEY_BASE`, `GITLAB_SECRETS_DB_KEY_BASE`, and `GITLAB_SECRETS_SECRET_KEY_BASE`. These values are used for the following:



- `GITLAB_SECRETS_OTP_KEY_BASE` is used to encrypt 2FA secrets in the database. If you lose or rotate this secret, none of your users will be able to log in using 2FA.

- `GITLAB_SECRETS_DB_KEY_BASE` is used to encrypt CI secret variables, as well as import credentials, in the database. If you lose or rotate this secret, you will not be able to use existing CI secrets.

- `GITLAB_SECRETS_SECRET_KEY_BASE` is used for password reset links, and other 'standard' auth features. If you lose or rotate this secret, password reset tokens in emails will reset.



> **Tip**: You can generate a random string using `pwgen -Bsv1 64` and assign it as the value of `GITLAB_SECRETS_DB_KEY_BASE`.



Start GitLab using:



```bash

docker-compose up

```



Alternatively, you can manually launch the `gitlab` container and the supporting `postgresql` and `redis` containers by following this three step guide.



Step 1. Launch a postgresql container



```bash

docker run --name gitlab-postgresql -d \

    --env 'DB_NAME=gitlabhq_production' \

    --env 'DB_USER=gitlab' --env 'DB_PASS=password' \

    --env 'DB_EXTENSION=pg_trgm' \

    --volume /data/gitlab/postgresql:/var/lib/postgresql \

    tiredofit/postgresql:13-latest

```



Step 2. Launch a redis container



```bash

docker run --name gitlab-redis -d \

    --volume /data/gitlab/redis:/var/lib/redis \

    tiredofit/redis:latest

```



Step 3. Launch the gitlab container



```bash

docker run --name gitlab -d \

    --link gitlab-postgresql:postgresql --link gitlab-redis:redisio \

    --publish 10022:22 --publish 10080:80 \

    --env 'GITLAB_PORT=10080' --env 'GITLAB_SSH_PORT=10022' \

    --env 'GITLAB_SECRETS_DB_KEY_BASE=long-and-random-alpha-numeric-string' \

    --env 'GITLAB_SECRETS_SECRET_KEY_BASE=long-and-random-alpha-numeric-string' \

    --env 'GITLAB_SECRETS_OTP_KEY_BASE=long-and-random-alpha-numeric-string' \

    --volume /data/gitlab/gitlab:/home/git/data \

    tiredofit/gitlab-ee:latest

```



*Please refer to [Available Configuration Parameters](#available-configuration-parameters) to understand `GITLAB_PORT` and other configuration options*



__NOTE__: Please allow a couple of minutes for the GitLab application to start.



Point your browser to `http://localhost:10080` and set a password for the `root` user account.



You should now have the GitLab application up and ready for testing. If you want to use this image in production then please read on.



*The rest of the document will use the docker command line. You can quite simply adapt your configuration into a `docker-compose.yml` file if you wish to do so.*



## Configuration



## Data Store



GitLab is a code hosting software and as such you don't want to lose your code when the docker container is stopped/deleted. To avoid losing any data, you should mount a volume at,



* `/home/git/data`



Note that if you are using the `docker-compose` approach, this has already been done for you.



SELinux users are also required to change the security context of the mount point so that it plays nicely with selinux.



```bash

mkdir -p /data/gitlab/gitlab

sudo chcon -Rt svirt_sandbox_file_t /data/gitlab/gitlab

```



Volumes can be mounted in docker by specifying the `-v` option in the docker run command.



```bash

docker run --name gitlab -d \

    --volume /data/gitlab/gitlab:/home/git/data \

    tiredofit/gitlab-ee:latest

```



## Database



### PostgreSQL



#### External PostgreSQL Server



The image also supports using an external PostgreSQL Server. This is also controlled via environment variables.



```sql

CREATE ROLE gitlab with LOGIN CREATEDB PASSWORD 'password';

CREATE DATABASE gitlabhq_production;

GRANT ALL PRIVILEGES ON DATABASE gitlabhq_production to gitlab;

```



Additionally since GitLab `8.6.0` the `pg_trgm` extension should also be loaded for the `gitlabhq_production` database.



We are now ready to start the GitLab application.



*Assuming that the PostgreSQL server host is 192.168.1.100*



```bash

docker run --name gitlab -d \

    --env 'DB_ADAPTER=postgresql' --env 'DB_HOST=192.168.1.100' \

    --env 'DB_NAME=gitlabhq_production' \

    --env 'DB_USER=gitlab' --env 'DB_PASS=password' \

    --volume /data/gitlab/gitlab:/home/git/data \

    tiredofit/gitlab-ee:latest

```



#### Linking to PostgreSQL Container



You can link this image with a postgresql container for the database requirements. The alias of the postgresql server container should be set to **postgresql** while linking with the gitlab image.



If a postgresql container is linked, only the `DB_ADAPTER`, `DB_HOST` and `DB_PORT` settings are automatically retrieved using the linkage. You may still need to set other database connection parameters such as the `DB_NAME`, `DB_USER`, `DB_PASS` and so on.



To illustrate linking with a postgresql container, we will use the [tiredofit/postgresql](https://github.com/tiredofit/postgresql) image. When using postgresql image in production you should mount a volume for the postgresql data store. Please refer the [README](https://github.com/tiredofit/postgresql/blob/master/README.md) of postgresql for details.



First, lets pull the postgresql image from the docker index.



```bash

docker pull docker.io/tiredofdit/postgresql:13-latest

```



For data persistence lets create a store for the postgresql and start the container.



SELinux users are also required to change the security context of the mount point so that it plays nicely with selinux.



```bash

mkdir -p /data/gitlab/postgresql

sudo chcon -Rt svirt_sandbox_file_t /data/gitlab/postgresql

```



The run command looks like this.



```bash

docker run --name gitlab-postgresql -d \

    --env 'DB_NAME=gitlabhq_production' \

    --env 'DB_USER=gitlab' --env 'DB_PASS=password' \

    --env 'DB_EXTENSION=pg_trgm' \

    --volume /data/gitlab/postgresql:/var/lib/postgresql \

    tiredofit/postgresql:13-latest

```



The above command will create a database named `gitlabhq_production` and also create a user named `gitlab` with the password `password` with access to the `gitlabhq_production` database.



We are now ready to start the GitLab application.



```bash

docker run --name gitlab -d --link gitlab-postgresql:postgresql \

    --volume /data/gitlab/gitlab:/home/git/data \

    tiredofit/gitlab-ee:latest

```



Here the image will also automatically fetch the `DB_NAME`, `DB_USER` and `DB_PASS` variables from the postgresql container as they are specified in the `docker run` command for the postgresql container. This is made possible using the magic of docker links and works with the following images:



 - [postgres](https://hub.docker.com/_/postgres/)

 - [tiredofit/postgresql](https://hub.docker.com/r/tiredofit/postgresql/)



## Redis



GitLab uses the redis server for its key-value data store. The redis server connection details can be specified using environment variables.



### External Redis Server



The image can be configured to use an external redis server. The configuration should be specified using environment variables while starting the GitLab image.



*Assuming that the redis server host is 192.168.1.100*



```bash

docker run --name gitlab -it --rm \

    --env 'REDIS_HOST=192.168.1.100' --env 'REDIS_PORT=6379' \

    tiredofit/gitlab-ee:latest

```



### Linking to Redis Container



You can link this image with a redis container to satisfy gitlab's redis requirement. The alias of the redis server container should be set to **redisio** while linking with the gitlab image.



To illustrate linking with a redis container, we will use the [tiredofit/redis](https://github.com/tiredofit/redis) image. Please refer the [README](https://github.com/tiredofit/redis/blob/master/README.md) of redis for details.



First, lets pull the redis image from the docker index.



```bash

docker pull docker.io/tiredofdit/redis:latest

```



Lets start the redis container



```bash

docker run --name gitlab-redis -d \

    --volume /data/gitlab/redis:/var/lib/redis \

    tiredofit/redis:latest

```



We are now ready to start the GitLab application.



```bash

docker run --name gitlab -d --link gitlab-redis:redisio \

    tiredofit/gitlab-ee:latest

```



### Mail



The mail configuration should be specified using environment variables while starting the GitLab image. The configuration defaults to using gmail to send emails and requires the specification of a valid username and password to login to the gmail servers.



If you are using Gmail then all you need to do is:



```bash

docker run --name gitlab -d \

    --env '[email protected]' --env 'SMTP_PASS=PASSWORD' \

    --volume /data/gitlab/gitlab:/home/git/data \

    tiredofit/gitlab-ee:latest

```



Please refer the [Available Configuration Parameters](#available-configuration-parameters) section for the list of SMTP parameters that can be specified.



#### Reply by email



GitLab adds support for commenting on issues by replying to emails.



To enable this feature you need to provide IMAP configuration parameters that will allow GitLab to connect to your mail server and read mails. Additionally, you may need to specify `GITLAB_INCOMING_EMAIL_ADDRESS` if your incoming email address is not the same as the `IMAP_USER`.



If your email provider supports email [sub-addressing](https://en.wikipedia.org/wiki/Email_address#Sub-addressing) then you should add the `+%{key}` placeholder after the user part of the email address, eg. `GITLAB_INCOMING_EMAIL_ADDRESS=reply+%{key}@example.com`. Please read the [documentation on reply by email](http://doc.gitlab.com/ce/incoming_email/README.html) to understand the requirements for this feature.



If you are using Gmail then all you need to do is:



```bash

docker run --name gitlab -d \

    --env '[email protected]' --env 'IMAP_PASS=PASSWORD' \

    --env 'GITLAB_INCOMING_EMAIL_ADDRESS=USER+%{key}@gmail.com' \

    --volume /data/gitlab/gitlab:/home/git/data \

    tiredofit/gitlab-ee:latest

```



Please refer the [Available Configuration Parameters](#available-configuration-parameters) section for the list of IMAP parameters that can be specified.



### SSL



Access to the gitlab application can be secured using SSL so as to prevent unauthorized access to the data in your repositories. While a CA certified SSL certificate allows for verification of trust via the CA, a self signed certificate can also provide an equal level of trust verification as long as each client takes some additional steps to verify the identity of your website. I will provide instructions on achieving this towards the end of this section.



Jump to the [Using HTTPS with a load balancer](#using-https-with-a-load-balancer) section if you are using a load balancer such as hipache, haproxy or nginx.



To secure your application via SSL you basically need two things:

- **Private key (.key)**

- **SSL certificate (.crt)**



When using CA certified certificates, these files are provided to you by the CA. When using self-signed certificates you need to generate these files yourself. Skip to [Strengthening the server security](#strengthening-the-server-security) section if you are armed with CA certified SSL certificates.



#### Generation of a Self Signed Certificate



Generation of a self-signed SSL certificate involves a simple 3-step procedure:



**STEP 1**: Create the server private key



```bash

openssl genrsa -out gitlab.key 2048

```



**STEP 2**: Create the certificate signing request (CSR)



```bash

openssl req -new -key gitlab.key -out gitlab.csr

```



**STEP 3**: Sign the certificate using the private key and CSR



```bash

openssl x509 -req -days 3650 -in gitlab.csr -signkey gitlab.key -out gitlab.crt

```



Congratulations! You now have a self-signed SSL certificate valid for 10 years.



#### Strengthening the server security



This section provides you with instructions to [strengthen your server security](https://raymii.org/s/tutorials/Strong_SSL_Security_On_nginx.html). To achieve this we need to generate stronger DHE parameters.



```bash

openssl dhparam -out dhparam.pem 2048

```



#### Installation of the SSL Certificates



Out of the four files generated above, we need to install the `gitlab.key`, `gitlab.crt` and `dhparam.pem` files at the gitlab server. The CSR file is not needed, but do make sure you safely backup the file (in case you ever need it again).



The default path that the gitlab application is configured to look for the SSL certificates is at `/home/git/data/certs`, this can however be changed using the `SSL_KEY_PATH`, `SSL_CERTIFICATE_PATH` and `SSL_DHPARAM_PATH` configuration options.



If you remember from above, the `/home/git/data` path is the path of the [data store](#data-store), which means that we have to create a folder named `certs/` inside `/data/gitlab/gitlab/` and copy the files into it and as a measure of security we'll update the permission on the `gitlab.key` file to only be readable by the owner.



```bash

mkdir -p /data/gitlab/gitlab/certs

cp gitlab.key /data/gitlab/gitlab/certs/

cp gitlab.crt /data/gitlab/gitlab/certs/

cp dhparam.pem /data/gitlab/gitlab/certs/

chmod 400 /data/gitlab/gitlab/certs/gitlab.key

```



Great! we are now just one step away from having our application secured.



#### Enabling HTTPS support



HTTPS support can be enabled by setting the `GITLAB_HTTPS` option to `true`. Additionally, when using self-signed SSL certificates you need to the set `SSL_SELF_SIGNED` option to `true` as well. Assuming we are using self-signed certificates



```bash

docker run --name gitlab -d \

    --publish 10022:22 --publish 10080:80 --publish 10443:443 \

    --env 'GITLAB_SSH_PORT=10022' --env 'GITLAB_PORT=10443' \

    --env 'GITLAB_HTTPS=true' --env 'SSL_SELF_SIGNED=true' \

    --volume /data/gitlab/gitlab:/home/git/data \

    tiredofit/gitlab-ee:latest

```



In this configuration, any requests made over the plain http protocol will automatically be redirected to use the https protocol. However, this is not optimal when using a load balancer.



#### Configuring HSTS



HSTS if supported by the browsers makes sure that your users will only reach your sever via HTTPS. When the user comes for the first time it sees a header from the server which states for how long from now this site should only be reachable via HTTPS - that's the HSTS max-age value.



With `NGINX_HSTS_MAXAGE` you can configure that value. The default value is `31536000` seconds. If you want to disable a already sent HSTS MAXAGE value, set it to `0`.



```bash

docker run --name gitlab -d \

 --env 'GITLAB_HTTPS=true' --env 'SSL_SELF_SIGNED=true' \

 --env 'NGINX_HSTS_MAXAGE=2592000' \

 --volume /data/gitlab/gitlab:/home/git/data \

 tiredofit/gitlab-ee:latest

```



If you want to completely disable HSTS set `NGINX_HSTS_ENABLED` to `false`.



#### Using HTTPS with a load balancer



Load balancers like nginx/haproxy/hipache talk to backend applications over plain http and as such the installation of ssl keys and certificates are not required and should **NOT** be installed in the container. The SSL configuration has to instead be done at the load balancer.



However, when using a load balancer you **MUST** set `GITLAB_HTTPS` to `true`. Additionally you will need to set the `SSL_SELF_SIGNED` option to `true` if self signed SSL certificates are in use.



With this in place, you should configure the load balancer to support handling of https requests. But that is out of the scope of this document. Please refer to [Using SSL/HTTPS with HAProxy](http://seanmcgary.com/posts/using-sslhttps-with-haproxy) for information on the subject.



When using a load balancer, you probably want to make sure the load balancer performs the automatic http to https redirection. Information on this can also be found in the link above.



In summation, when using a load balancer, the docker command would look for the most part something like this:



```bash

docker run --name gitlab -d \

    --publish 10022:22 --publish 10080:80 \

    --env 'GITLAB_SSH_PORT=10022' --env 'GITLAB_PORT=443' \

    --env 'GITLAB_HTTPS=true' --env 'SSL_SELF_SIGNED=true' \

    --volume /data/gitlab/gitlab:/home/git/data \

    tiredofit/gitlab-ee:latest

```



Again, drop the `--env 'SSL_SELF_SIGNED=true'` option if you are using CA certified SSL certificates.



In case GitLab responds to any kind of POST request (login, OAUTH, changing settings etc.) with a 422 HTTP Error, consider adding this to your reverse proxy configuration:



`proxy_set_header X-Forwarded-Ssl on;` (nginx format)



#### Establishing trust with your server



This section deals will self-signed ssl certificates. If you are using CA certified certificates, your done.



This section is more of a client side configuration so as to add a level of confidence at the client to be 100 percent sure they are communicating with whom they think they.



This is simply done by adding the servers certificate into their list of trusted certificates. On ubuntu, this is done by copying the `gitlab.crt` file to `/usr/local/share/ca-certificates/` and executing `update-ca-certificates`.



Again, this is a client side configuration which means that everyone who is going to communicate with the server should perform this configuration on their machine. In short, distribute the `gitlab.crt` file among your developers and ask them to add it to their list of trusted ssl certificates. Failure to do so will result in errors that look like this:



```bash

git clone https://git.local.host/gitlab-ee.git

fatal: unable to access 'https://git.local.host/gitlab-ee.git': server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none

```



You can do the same at the web browser. Instructions for installing the root certificate for firefox can be found [here](http://portal.threatpulse.com/docs/sol/Content/03Solutions/ManagePolicy/SSL/ssl_firefox_cert_ta.htm). You will find similar options chrome, just make sure you install the certificate under the authorities tab of the certificate manager dialog.



There you have it, that's all there is to it.



#### Installing Trusted SSL Server Certificates



If your GitLab CI server is using self-signed SSL certificates then you should make sure the GitLab CI server certificate is trusted on the GitLab server for them to be able to talk to each other.



The default path image is configured to look for the trusted SSL certificates is at `/home/git/data/certs/ca.crt`, this can however be changed using the `SSL_CA_CERTIFICATES_PATH` configuration option.



Copy the `ca.crt` file into the certs directory on the [datastore](#data-store). The `ca.crt` file should contain the root certificates of all the servers you want to trust. With respect to GitLab CI, this will be the contents of the gitlab_ci.crt file as described in the [README](https://github.com/tiredofit/docker-gitlab-ci/blob/master/README.md#ssl) of the [docker-gitlab-ci](https://github.com/tiredofit/docker-gitlab-ci) container.



By default, our own server certificate [gitlab.crt](#generation-of-self-signed-certificate) is added to the trusted certificates list.



### Deploy to a subdirectory (relative url root)



By default GitLab expects that your application is running at the root (eg. /). This section explains how to run your application inside a directory.



Let's assume we want to deploy our application to '/git'. GitLab needs to know this directory to generate the appropriate routes. This can be specified using the `GITLAB_RELATIVE_URL_ROOT` configuration option like so:



```bash

docker run --name gitlab -it --rm \

    --env 'GITLAB_RELATIVE_URL_ROOT=/git' \

    --volume /data/gitlab/gitlab:/home/git/data \

    tiredofit/gitlab-ee:latest

```



GitLab will now be accessible at the `/git` path, e.g. `http://www.example.com/git`.



**Note**: *The `GITLAB_RELATIVE_URL_ROOT` parameter should always begin with a slash and* **SHOULD NOT** *have any trailing slashes.*



### OmniAuth Integration



GitLab leverages OmniAuth to allow users to sign in using Twitter, GitHub, and other popular services. Configuring OmniAuth does not prevent standard GitLab authentication or LDAP (if configured) from continuing to work. Users can choose to sign in using any of the configured mechanisms.



Refer to the GitLab [documentation](http://doc.gitlab.com/ce/integration/omniauth.html) for additional information.



#### CAS3



To enable the CAS OmniAuth provider you must register your application with your CAS instance. This requires the service URL GitLab will supply to CAS. It should be something like: https://git.example.com:443/users/auth/cas3/callback?url. By default handling for SLO is enabled, you only need to configure CAS for backchannel logout.



For example, if your cas server url is `https://sso.example.com`, then adding `--env 'OAUTH_CAS3_SERVER=https://sso.example.com'` to the docker run command enables support for CAS3 OAuth. Please refer to [Available Configuration Parameters](#available-configuration-parameters) for additional CAS3 configuration parameters.



#### Authentiq



To enable the Authentiq OmniAuth provider for passwordless authentication you must register an application with [Authentiq](https://www.authentiq.com/). Please refer to the GitLab [documentation](https://docs.gitlab.com/ce/administration/auth/authentiq.html) for the procedure to generate the client ID and secret key with Authentiq.



Once you have the API client id and client secret generated, configure them using the `OAUTH_AUTHENTIQ_CLIENT_ID` and `OAUTH_AUTHENTIQ_CLIENT_SECRET` environment variables respectively.



For example, if your API key is `xxx` and the API secret key is `yyy`, then adding `--env 'OAUTH_AUTHENTIQ_CLIENT_ID=xxx' --env 'OAUTH_AUTHENTIQ_CLIENT_SECRET=yyy'` to the docker run command enables support for Authentiq OAuth.



You may want to specify `OAUTH_AUTHENTIQ_REDIRECT_URI` as well. The OAuth scope can be altered as well with `OAUTH_AUTHENTIQ_SCOPE` (defaults to `'aq:name email~rs address aq:push'`).



#### Google



To enable the Google OAuth2 OmniAuth provider you must register your application with Google. Google will generate a client ID and secret key for you to use. Please refer to the GitLab [documentation](http://doc.gitlab.com/ce/integration/google.html) for the procedure to generate the client ID and secret key with google.



Once you have the client ID and secret keys generated, configure them using the `OAUTH_GOOGLE_API_KEY` and `OAUTH_GOOGLE_APP_SECRET` environment variables respectively.



For example, if your client ID is `xxx.apps.googleusercontent.com` and client secret key is `yyy`, then adding `--env 'OAUTH_GOOGLE_API_KEY=xxx.apps.googleusercontent.com' --env 'OAUTH_GOOGLE_APP_SECRET=yyy'` to the docker run command enables support for Google OAuth.



You can also restrict logins to a single domain by adding `--env "OAUTH_GOOGLE_RESTRICT_DOMAIN='example.com'"`.

#### SAML



GitLab can be configured to act as a SAML 2.0 Service Provider (SP). This allows GitLab to consume assertions from a SAML 2.0 Identity Provider (IdP) such as Microsoft ADFS to authenticate users. Please refer to the GitLab [documentation](http://doc.gitlab.com/ce/integration/saml.html).



The following parameters have to be configured to enable SAML OAuth support in this image: `OAUTH_SAML_ASSERTION_CONSUMER_SERVICE_URL`, `OAUTH_SAML_IDP_CERT_FINGERPRINT`, `OAUTH_SAML_IDP_SSO_TARGET_URL`, `OAUTH_SAML_ISSUER` and `OAUTH_SAML_NAME_IDENTIFIER_FORMAT`.



You can also override the default "Sign in with" button label with `OAUTH_SAML_LABEL`.



Please refer to [Available Configuration Parameters](#available-configuration-parameters) for the default configurations of these parameters.



#### Crowd

#### Microsoft Azure



To enable the Microsoft Azure OAuth2 OmniAuth provider you must register your application with Azure. Azure will generate a Client ID, Client secret and Tenant ID for you to use. Please refer to the GitLab [documentation](http://doc.gitlab.com/ce/integration/azure.html) for the procedure.



Once you have the Client ID, Client secret and Tenant ID generated, configure them using the `OAUTH_AZURE_API_KEY`, `OAUTH_AZURE_API_SECRET` and `OAUTH_AZURE_TENANT_ID` environment variables respectively.



For example, if your Client ID is `xxx`, the Client secret is `yyy` and the Tenant ID is `zzz`, then adding `--env 'OAUTH_AZURE_API_KEY=xxx' --env 'OAUTH_AZURE_API_SECRET=yyy' --env 'OAUTH_AZURE_TENANT_ID=zzz'` to the docker run command enables support for Microsoft Azure OAuth.



### External Issue Trackers



Since version `7.10.0` support for external issue trackers can be enabled in the "Service Templates" section of the settings panel.



If you are using the [docker-redmine](https://github.com/tiredofit/docker-redmine) image, you can *one up* the gitlab integration with redmine by adding `--volumes-from=gitlab` flag to the docker run command while starting the redmine container.



By using the above option the `/home/git/data/repositories` directory will be accessible by the redmine container and now you can add your git repository path to your redmine project. If, for example, in your gitlab server you have a project named `opensource/gitlab`, the bare repository will be accessible at `/home/git/data/repositories/opensource/gitlab.git` in the redmine container.



### Host UID / GID Mapping



Per default the container is configured to run gitlab as user and group `git` with `uid` and `gid` `1000`. The host possibly uses this ids for different purposes leading to unfavorable effects. From the host it appears as if the mounted data volumes are owned by the host's user/group `1000`.



Also the container processes seem to be executed as the host's user/group `1000`. The container can be configured to map the `uid` and `gid` of `git` to different ids on host by passing the environment variables `USERMAP_UID` and `USERMAP_GID`. The following command maps the ids to user and group `git` on the host.



```bash

docker run --name gitlab -it --rm [options] \

    --env "USERMAP_UID=$(id -u git)" --env "USERMAP_GID=$(id -g git)" \

    tiredofit/gitlab-ee:latest

```



When changing this mapping, all files and directories in the mounted data volume `/home/git/data` have to be re-owned by the new ids. This can be achieved automatically using the following command:



```bash

docker run --name gitlab -d [OPTIONS] \

    tiredofit/gitlab-ee:latest app:sanitize

```



### Piwik



If you want to monitor your gitlab instance with [Piwik](http://piwik.org/), there are two options to setup: `PIWIK_URL` and `PIWIK_SITE_ID`.

These options should contain something like:



- `PIWIK_URL=piwik.example.org`

- `PIWIK_SITE_ID=42`



### Available Configuration Parameters



*Please refer the docker run command options for the `--env-file` flag where you can specify all required environment variables in a single file. This will save you from writing a potentially long docker run command. Alternatively you can use docker-compose.*



Along with the Environment Variables from the [Base image](https://hub.docker.com/r/tiredofit/alpine), below is the complete list of available options that can be used to customize your installation.

## Maintenance



## Creating backups



GitLab defines a rake task to take a backup of your gitlab installation. The backup consists of all git repositories, uploaded files and as you might expect, the sql database.



Before taking a backup make sure the container is stopped and removed to avoid container name conflicts.



```bash

docker stop gitlab && docker rm gitlab

```



Execute the rake task to create a backup.



```bash

docker run --name gitlab -it -e MODE=RAKE -e RAKE_TASK=gitlab:backup:create --rm [OPTIONS] \

    tiredofit/gitlab-ee:latest

```



A backup will be created in the backups folder of the [Data Store](#data-store). You can change the location of the backups using the `GITLAB_BACKUP_DIR` configuration parameter.



*P.S. Backups can also be generated on a running instance using `docker exec` as described in the [Rake Tasks](#rake-tasks) section. However, to avoid undesired side-effects, I advice against running backup and restore operations on a running instance.*



## Restoring Backups



GitLab also defines a rake task to restore a backup.



Before performing a restore make sure the container is stopped and removed to avoid container name conflicts.



```bash

docker stop gitlab && docker rm gitlab

```



If this is a fresh database that you're doing the restore on, first

you need to prepare the database:



```bash

docker run --name gitlab -it -e MODE=RAKE -e RAKE_TASK=db:setup--rm [OPTIONS] \

    tiredofit/gitlab-ee:latest

```



Execute the rake task to restore a backup. Make sure you run the container in interactive mode `-it`.



```bash

docker run --name gitlab -it -e MODE=RAKE -e RAKE_TASK=gitlab:backup:restore --rm [OPTIONS] \

    tiredofit/gitlab-ee:latest

```



The list of all available backups will be displayed in reverse chronological order. Select the backup you want to restore and continue.



To avoid user interaction in the restore operation, specify the timestamp of the backup using the `BACKUP` argument to the rake task.



```bash

docker run --name gitlab -it -e MODE=RAKE -e RAKE_TASK=gitlab:backup:restore BACKUP=1417624827 --rm [OPTIONS] \

    tiredofit/gitlab-ee:latest

```



## Host Key Backups (ssh)



SSH keys are not backed up in the normal gitlab backup process. You

will need to backup the `ssh/` directory in the data volume by hand

and you will want to restore it prior to doing a gitlab restore.



## Automated Backups



The image can be configured to automatically take backups `daily`, `weekly` or `monthly` using the `GITLAB_BACKUP_SCHEDULE` configuration option.



Daily backups are created at `GITLAB_BACKUP_TIME` which defaults to `04:00` everyday. Weekly backups are created every Sunday at the same time as the daily backups. Monthly backups are created on the 1st of every month at the same time as the daily backups.



By default, when automated backups are enabled, backups are held for a period of 7 days. While when automated backups are disabled, the backups are held for an infinite period of time. This behavior can be configured via the `GITLAB_BACKUP_EXPIRY` option.



### Amazon Web Services (AWS) Remote Backups



The image can be configured to automatically upload the backups to an AWS S3 bucket. To enable automatic AWS backups first add `--env 'AWS_BACKUPS=true'` to the docker run command. In addition `AWS_BACKUP_REGION` and `AWS_BACKUP_BUCKET` must be properly configured to point to the desired AWS location. Finally an IAM user must be configured with appropriate access permission and their AWS keys exposed through `AWS_BACKUP_ACCESS_KEY_ID` and `AWS_BACKUP_SECRET_ACCESS_KEY`.



More details about the appropriate IAM user properties can found on [doc.gitlab.com](http://doc.gitlab.com/ce/raketasks/backup_restore.html#upload-backups-to-remote-cloud-storage)



For remote backup to selfhosted s3 compatible storage, use `AWS_BACKUP_ENDPOINT`.



AWS uploads are performed alongside normal backups, both through the appropriate `app:rake` command and when an automatic backup is performed.



### Google Cloud Storage (GCS) Remote Backups



The image can be configured to automatically upload the backups to an Google Cloud Storage bucket. To enable automatic GCS backups first add `--env 'GCS_BACKUPS=true'` to the docker run command. In addition `GCS_BACKUP_BUCKET` must be properly configured to point to the desired GCS location.

Finally a couple of `Interoperable storage access keys` user must be created and their keys exposed through `GCS_BACKUP_ACCESS_KEY_ID` and `GCS_BACKUP_SECRET_ACCESS_KEY`.



More details about the Cloud storage interoperability  properties can found on [cloud.google.com/storage](https://cloud.google.com/storage/docs/interoperability)



GCS uploads are performed alongside normal backups, both through the appropriate `app:rake` command and when an automatic backup is performed.



## Rake Tasks



The `app:rake` command allows you to run gitlab rake tasks. To run a rake task simply specify the task to be executed to the `app:rake` command. For example, if you want to gather information about GitLab and the system it runs on.



```bash

docker run --name gitlab -it -e MODE=RAKE -e RAKE_TASK=gitlab:env:info --rm [OPTIONS] \

    tiredofit/gitlab-ee:latest

```



You can also use `docker exec` to run raketasks on running gitlab instance. For example,



```bash

docker exec --user git -it gitlab bundle exec rake gitlab:env:info RAILS_ENV=production

```



Similarly, to import bare repositories into GitLab project instance



```bash

docker run --name gitlab -it -e MODE=RAKE -e RAKE_TASK=gitlab:import:repos --rm [OPTIONS] \

    tiredofit/gitlab-ee:latest

```



Or



```bash

docker exec -it gitlab sudo -HEu git bundle exec rake gitlab:import:repos RAILS_ENV=production

```



For a complete list of available rake tasks please refer https://github.com/gitlabhq/gitlabhq/tree/master/doc/raketasks or the help section of your gitlab installation.



*P.S. Please avoid running the rake tasks for backup and restore operations on a running gitlab instance.*



To use the `app:rake` command with `docker-compose` use the following command.



```bash

# For stopped instances

docker-compose run --rm gitlab -e MODE=RAKE -e RAKE_TASK=gitlab:env:info

docker-compose run --rm gitlab -e MODE=RAKE -e RAKE_TASK=gitlab:import:repos



# For running instances

docker-compose exec --user git gitlab bundle exec rake gitlab:env:info RAILS_ENV=production

docker-compose exec gitlab sudo -HEu git bundle exec rake gitlab:import:repos RAILS_ENV=production

```



## Import Repositories



Copy all the **bare** git repositories to the `repositories/` directory of the [data store](#data-store) and execute the `gitlab:import:repos` rake task like so:



```bash

docker run --name gitlab -it -e MODE=RAKE -e RAKE_TASK=gitlab:import:repos --rm [OPTIONS] \

    tiredofit/gitlab-ee:latest

```



Watch the logs and your repositories should be available into your new gitlab container.



See [Rake Tasks](#rake-tasks) for more information on executing rake tasks.

Usage when using `docker-compose` can also be found there.



## Upgrading



> **Important Notice**

>

GitLabHQ releases new versions on the 22nd of every month, bugfix releases immediately follow. I update this project almost immediately when a release is made (at least it has been the case so far). If you are using the image in production environments I recommend that you delay updates by a couple of days after the gitlab release, allowing some time for the dust to settle down.



To upgrade to newer gitlab releases, simply follow this 4 step upgrade procedure.



- **Step 1**: Update the docker image.



```bash

docker pull docker.io/tiredofdit/gitlab-ee:latest

```



- **Step 2**: Stop and remove the currently running image



```bash

docker stop gitlab

docker rm gitlab

```



- **Step 3**: Create a backup



```bash

docker run --name gitlab -it -e MODE=RAKE -e RAKE_TASK=gitlab:backup:create --rm [OPTIONS] tiredofit/gitlab:x.x.x

```



Replace `x.x.x` with the version you are upgrading from. For example, if you are upgrading from version `6.0.0`, set `x.x.x` to `6.0.0`



- **Step 4**: Start the image



```bash

docker run --name gitlab -d [OPTIONS] tiredofit/gitlab-ee:latest

```
