# Kartoza docker-geoserver



* A simple docker container that runs GeoServer influenced by this [docker recipe](https://github.com/eliotjordan/docker-geoserver/blob/master/Dockerfile).

* The image has environment variables that allow users to configure GeoServer based on [running-in-production](https://docs.geoserver.org/latest/en/user/production/index.html)

* The image uses [kartoza/postgis](https://github.com/kartoza/docker-postgis/) as a

 database backend. You can use any other PostgreSQL image

but adjust the environment variables accordingly.



## Getting the image



There are various ways to get the image onto your system:



   * Pulling from Dockerhub

   * Local build using docker-compose



### Pulling from Dockerhub



The preferred way (but using the most bandwidth for the initial image) is to

get our docker-trusted build like this:



``` shell

VERSION=2.25.2

docker pull kartoza/geoserver:$VERSION

```

**Note** Although the images are tagged and backed by unit tests

it is recommended to use tagged versions with dates i.e. 

`kartoza/geoserver:$VERSION--v2024.03.31`.The first date available

from [dockerhub](https://hub.docker.com/repository/docker/kartoza/geoserver/tags?page=1&ordering=last_updated)

It would be the first version for that series. Successive builds that fix [issues](https://github.com/kartoza/docker-geoserver/issues) 

tend to override the tagged images and also produce dated images.



### Building the image



### Local build using repository checkout



To build yourself with a local checkout using the docker-compose-build.yml:



1. Clone the GitHub repository:



   ``` shell

   git clone https://github.com/kartoza/docker-geoserver

   ```

2. Edit the [build arguments](https://github.com/kartoza/docker-geoserver/blob/master/.env) in the `.env` file:



3. Build the container and spin up the services

   ``` shell

   cd docker-geoserver

   docker-compose -f docker-compose-build.yml up -d geoserver-prod --build

   ```



### Building with a specific version of  Tomcat



To build using a specific tagged release of the tomcat image set the

`IMAGE_VERSION` build arg: 

See the [dockerhub tomcat](https://hub.docker.com/_/tomcat/)

for available tags.



```

VERSION=2.25.2

IMAGE_VERSION=9.0.91-jdk11-temurin-focal

docker build --build-arg IMAGE_VERSION=${IMAGE_VERSION} --build-arg GS_VERSION=${VERSION} -t kartoza/geoserver:${VERSION} .

```



For some recent builds, it is necessary to set the JAVA_PATH as well (e.g. Apache Tomcat/9.0.36)

```

docker build --build-arg IMAGE_VERSION=9.0.91-jdk11-temurin-focal --build-arg JAVA_HOME=/usr/local/openjdk-11/bin/java --build-arg GS_VERSION=2.25.2 -t kartoza/geoserver:2.25.2 .

```



**Note:** Please check the [GeoServer documentation](https://docs.geoserver.org/stable/en/user/production/index.html) 

to see which Tomcat versions are supported.



The current build uses the base image `tomcat:9.0.91-jdk11-temurin-focal` because of the dependency on

`libgdal-java`. The tomcat base images > focal will not

have the java bindings for the [GDAL plugin](https://osgeo-org.atlassian.net/browse/GEOT-7412?focusedCommentId=84733)

hence the container will not support the gdal plugin working if you build using base image > focal.



### Building on Windows



These instructions detail the recommended process for reliably building this on Windows.



Prerequisites - You will need to have this software preinstalled on the system being used to build the Geoserver image:



   * Docker Desktop with WSL2

   * [Java JDK](https://jdk.java.net/)

   * [Conda](https://conda.io/)

   * GDAL (Install with Conda)



Add the conda-forge channel to your conda installation:



```bash

conda config --add channels conda-forge

```



Now create a new conda environment with GDAL, installed from conda. Ensure that this environment is active when running

the docker build, e.g.



```bash

conda create -n geoserver-build -c conda-forge python gdal

conda activate geoserver-build

```



Modify the `.env` with the appropriate environment variables. It is recommended that short paths (without whitespace) 

are used with forward slashes to prevent errors. You can get the current Java command short path with PowerShell:



```bash

(New-Object -ComObject Scripting.FileSystemObject).GetFile((get-command java).Source).ShortPath

```



Running the above command should yield a path similar to `C:/PROGRA~1/Java/JDK-15~1.2/bin/java.exe`, which can be 

assigned to `JAVA_HOME` in the environment configuration file.



Then run the docker build commands. If you encounter issues, you may want to ensure that you try to build the image 

without the cache and then run docker up separately:



```bash

docker-compose -f docker-compose-build.yml build --force-rm --no-cache

docker-compose -f docker-compose-build.yml up -d

```



## Environment Variables

A full list of environment variables are specified in the [.env](https://github.com/kartoza/docker-geoserver/blob/develop/.env) file



### Default installed extensions



The image activates the [default_stable_extensions](https://github.com/kartoza/docker-geoserver/blob/develop/build_data/required_plugins.txt) listed below on container start:



* vectortiles-plugin

* wps-plugin

* libjpeg-turbo-plugin

* control-flow-plugin

* pyramid-plugin

* gdal-plugin

* monitor-plugin

* inspire-plugin

* csw-plugin



If you wish to exclude any of the default activated plugins you will need to set

```bash

ACTIVE_EXTENSIONS=${Default_extension} - skipped_default_extension

```



i.e. 

```

ACTIVE_EXTENSIONS=control-flow-plugin,csw-iso-plugin,csw-plugin,gdal-plugin,inspire-plugin,monitor-plugin,pyramid-plugin,vectortiles-plugin,wps-plugin

```

will skip activating libjpeg-turbo-plugin.



The variable `ACTIVE_EXTENSIONS` is used to specify a set of plugins to enable, if left empty or unset the following 

will be enabled : [list of default plugins](https://github.com/kartoza/docker-geoserver/blob/develop/build_data/required_plugins.txt)



####  Activate stable extensions during the contain startup



The environment variable `STABLE_EXTENSIONS` is used to activate extensions listed in

[stable_plugins](https://sourceforge.net/projects/geoserver/files/GeoServer/2.25.2/extensions/)



**Note:** The plugins listed in the url is of the format `geoserver-2.25.2-wps-plugin.zip`, but the env

variable expects the env to be of the format `wps-plugin`. Always consult the url to see which plugins 

are available. The text file [stable_plugins.txt](https://github.com/kartoza/docker-geoserver/blob/master/build_data/stable_plugins.txt)

contains a curated list of plugins but might be out of date in some cases.



Example



```

ie VERSION=2.25.2

docker run -d -p 8600:8080 --name geoserver -e STABLE_EXTENSIONS=charts-plugin,db2-plugin kartoza/geoserver:${VERSION}



```

You can pass any comma-separated extensions as defined in [stable_plugins](https://sourceforge.net/projects/geoserver/files/GeoServer/2.25.2/extensions/)



####  Activate community extensions during contain startup



The environment variable `COMMUNITY_EXTENSIONS` can be used to activate extensions listed in

[community_plugins](https://build.geoserver.org/geoserver/2.25.x/community-latest/)



**Note:** The plugins listed in the url is of the format `geoserver-2.25-SNAPSHOT-cog-http-plugin.zip `, but the env

variable expects the env to be of the format `cog-http-plugin`. Always consult the url to see which plugins 

are available. The text file [community_plugins.txt](https://github.com/kartoza/docker-geoserver/blob/master/build_data/stable_plugins.txt)

contains a curated list of community plugins but might be out of date in some cases.



Example



```

ie VERSION=2.25.2

docker run -d -p 8600:8080 --name geoserver -e COMMUNITY_EXTENSIONS=gwc-sqlite-plugin,ogr-datastore-plugin kartoza/geoserver:${VERSION}

```



The image ships with extension zip files pre-downloaded. You can pass an additional environment variable

`FORCE_DOWNLOAD_COMMUNITY_EXTENSIONS=true` to download the latest community extensions during the initialisation of the container.



**Note:** If you experience an issue running community extensions

please check upstream before reporting the issue here. If an extension is no longer available you can build the extensions

following the guidelines from [GeoServer develop guidelines](https://docs.geoserver.org/latest/en/developer/maven-guide/index.html#building-extensions)



### Using sample data



The image ships with sample data. This can be used to familiarize yourself with GeoServer. This is not activated by default. You can activate it using the environment variable `boolean SAMPLE_DATA`.



```

ie VERSION=2.25.2

docker run -d -p 8600:8080 --name geoserver -e SAMPLE_DATA=true kartoza/geoserver:${VERSION}

```



### Enable disk quota storage in PostgreSQL backend



GeoServer defaults to using HSQL datastore for configuring disk quota. You can alternatively use 

a PostgreSQL backend as a disk quota store. When using a PostgreSQL backend, you need to have a running instance of the database which can be connected to. 



If you want to test it locally with docker-compose postgres db you need to specify these env variables:

```bash

DB_BACKEND=POSTGRES               

HOST=db                          

POSTGRES_PORT=5432                

POSTGRES_DB=gwc                   

POSTGRES_USER=${POSTGRES_USER}    

POSTGRES_PASS=${POSTGRES_PASS}    

SSL_MODE=allow                    

POSTGRES_SCHEMA=public           

DISK_QUOTA_SIZE=5 

```



#### Using SSL and Default PostgreSQL SSL certificates (kartoza/postgis backend)



When the environment variable `FORCE_SSL=TRUE` is set for the database container you

will need to set `SSL_MODE=allow` in the GeoServer container.



#### Using SSL certificates signed by a certificate authority (kartoza/postgis backend)



When the environment variable `FORCE_SSL=TRUE` is set for the database container you

will need to set `SSL_MODE` to either `verify-full` or `verify-ca`

for the GeoServer container. You will also need to mount the SSL certificates

you have done in the DB.



In the GeoServer container, the certificates need to be mounted to the folder

specified by the certificate directory ${CERT_DIR}



```

SSL_CERT_FILE=/etc/certs/fullchain.pem

SSL_KEY_FILE=/etc/certs/privkey.pem

SSL_CA_FILE=/etc/certs/root.crt

```



### Activating JNDI PostgreSQL connector

When defining vector stores you can use the JNDI pooling. To activate this, adjust the following environment 

variable `POSTGRES_JNDI=TRUE`. By default, the environment the 

variable is set to `FALSE`. Additionally, you will need to 

define parameters to connect to an existing PostgreSQL database



```

POSTGRES_JNDI=TRUE

HOST=${POSTGRES_HOSTNAME}

POSTGRES_DB=${POSTGRES_DB}

POSTGRES_USER=${POSTGRES_USER}

POSTGRES_PASS=${POSTGRES_PASS}

```



When defining the parameters for the store in GeoServer you will need to set

`jndiReferenceName=java:comp/env/jdbc/postgres`



### Running under SSL

You can use the environment variables to specify whether you want to run the GeoServer under SSL.

Credits to [letsencrpt](https://github.com/AtomGraph/letsencrypt-tomcat) for the solution to run under SSL.



If you set the environment variable `SSL=true` but do not provide the pem files (`fullchain.pem` and `privkey.pem`)

the container will generate self-signed SSL certificates.



```

ie VERSION=2.25.2

docker run -it --name geoserver  -e PKCS12_PASSWORD=geoserver -e JKS_KEY_PASSWORD=geoserver -e JKS_STORE_PASSWORD=geoserver -e SSL=true -p 8443:8443 -p 8600:8080 kartoza/geoserver:${VERSION}

```



If you already have your perm files (`fullchain.pem` and `privkey.pem`) you can mount the directory containing your keys as:



```

ie VERSION=2.25.2

docker run -it --name geo -v /etc/certs:/etc/certs  -e PKCS12_PASSWORD=geoserver -e JKS_KEY_PASSWORD=geoserver -e JKS_STORE_PASSWORD=geoserver -e SSL=true -p 8443:8443 -p 8600:8080 kartoza/geoserver:${VERSION}



```



You can also use a `PFX` file with this image.

Rename your PFX file as certificate.pfx and then mount the folder containing

your pfx file. This will be converted to perm files.



**Note** When using PFX files make sure that the `ALIAS_KEY` you specify as

an environment variable matches the `ALIAS_KEY` that was used when generating

your `PFX` key.



A full list of SSL variables is provided in [SSL Settings](https://github.com/kartoza/docker-geoserver/blob/develop/.env)



### Proxy Base URL



For the server to report a full proxy base URL, you need to pass

the following env variable i.e.



```

HTTP_PROXY_NAME

HTTP_PROXY_PORT

```



If you are running GeoServer under SSL with reverse proxy i.e. nginx you will need

to set the following env variables



Example below:



```bash

HTTP_PROXY_NAME=foo.org

HTTP_SCHEME=https

```



This will prevent the login form from sending insecure http post requests as experienced

in [login issue](https://github.com/kartoza/docker-geoserver/issues/293)



For SSL-based connections, the env variables are:



```

HTTPS_PROXY_NAME

HTTPS_PROXY_PORT

HTTPS_SCHEME

```



### Removing Tomcat extras



To include Tomcat extras including docs, examples, and the manager web app, set the

`TOMCAT_EXTRAS` environment variable to `true`:



**Note:** If `TOMCAT_EXTRAS` is set to true then you should configure  `TOMCAT_PASSWORD`

to use a strong password otherwise a randomly generated password is used.



```

ie VERSION=2.25.2

docker run -it --name geoserver  -e TOMCAT_EXTRAS=true -p 8600:8080 kartoza/geoserver:${VERSION}

```



**Note:** If `TOMCAT_EXTRAS` is set to false, requests to the root webapp ("/") will return HTTP status code 404. 

To issue a redirect to the GeoServer webapp ("/geoserver/web") set `ROOT_WEBAPP_REDIRECT=true`



### Upgrading the image to use a specific version

If you are migrating your GeoServer instance, from a lower 

version to a higher and do not need to update your master 

password, you will need to set the variable `EXISTING_DATA_DIR`. 



You can set the  env variable `EXISTING_DATA_DIR` to any value i.e.

`EXISTING_DATA_DIR=foo` or `EXISTING_DATA_DIR=false` 

When the environment variable is set it will ensure that the password initialization is skipped

during the startup procedure.



### Installing extra fonts



If you have downloaded extra fonts you can mount the folder to the path

`/opt/fonts`. This will ensure that all the `.ttf` or `.otf` files are copied to the correct

path during initialisation. This is useful for styling layers i.e. labeling using specific fonts.



```

ie VERSION=2.25.2

docker run -v fonts:/opt/fonts -p 8080:8080 -t kartoza/geoserver:${VERSION}

```



#### Google Fonts

You can use the environment variable `GOOGLE_FONTS_NAMES` to activate fonts defined in [Google fonts](https://github.com/google/fonts.git)



i.e.



```bash

ie VERSION=2.25.2

docker run -e GOOGLE_FONTS_NAMES=actor,akronim -p 8080:8080 -t kartoza/geoserver:${VERSION}

```



### Other Environment variables supported



You can find a full list of environment variables in [Generic Env variables](https://github.com/kartoza/docker-geoserver/blob/develop/.env)



**Note** The list below is not exhaustive of all values available.

Always consult the `.env` file to check possible values. 



* GEOSERVER_DATA_DIR=`PATH`

* ENABLE_JSONP=`true or false`

* MAX_FILTER_RULES=`Any integer`

* OPTIMIZE_LINE_WIDTH=`false or true`

* FOOTPRINTS_DATA_DIR=`PATH`

* GEOWEBCACHE_CACHE_DIR=`PATH`

* GEOSERVER_ADMIN_PASSWORD=`password`

* GEOSERVER_ADMIN_USER=`username`

* GEOSERVER_FILEBROWSER_HIDEFS=`false or true`

* XFRAME_OPTIONS=`"true"` - Based on [Xframe-options](https://docs.geoserver.org/latest/en/user/production/config.html#x-frame-options-policy)

* INITIAL_MEMORY=`size`: Initial Memory that Java can allocate, default `2G`

* MAXIMUM_MEMORY=`size`: Maximum Memory that Java can allocate, default `4G`

* 



### Control flow properties



The control flow module manages requests in GeoServer. Instructions on

what each parameter means can be read from [documentation](http://docs.geoserver.org/latest/en/user/extensions/controlflow/index.html).



The following env variables can be set



```bash

REQUEST_TIMEOUT=60

PARALLEL_REQUEST=100

GETMAP=10

REQUEST_EXCEL=4

SINGLE_USER=6

GWC_REQUEST=16

WPS_REQUEST=1000/d;30s

```



### Changing GeoServer password and username



You can pass the environment variables to change it on runtime.

```

GEOSERVER_ADMIN_PASSWORD

GEOSERVER_ADMIN_USER

```



The username and password are reinitialized each time the container starts. If you do not pass the env variables

`GEOSERVER_ADMIN_PASSWORD` the container will generate a new password which is visible in the

startup logs.



**Note:** When upgrading the `GEOSERVER_ADMIN_PASSWORD` and `GEOSERVER_ADMIN_USER` you will

need to mount the volume `settings:/settings` so that the lock-files generated by the `update_password.sh` are

persistent during initialization. See the example in [docker-compose-build](https://github.com/kartoza/docker-geoserver/blob/master/docker-compose-build.yml)



```

docker run --name "geoserver" -e GEOSERVER_ADMIN_USER=kartoza  -e GEOSERVER_ADMIN_PASSWORD=myawesomegeoserver -p 8080:8080 -d -t kartoza/geoserver

```



**Note:** The docker-compose recipe uses the password `myawesomegeoserver`. It is highly

recommended not to run the container in production using these values.



#### Docker secrets



To avoid passing sensitive information in environment variables, `_FILE` can be appended to

some variables to read from files present in the container. This is particularly useful

in conjunction with Docker secrets, as passwords can be loaded from `/run/secrets/` e.g.:



* -e GEOSERVER_ADMIN_PASSWORD_FILE=/run/secrets/



For more information see [https://docs.docker.com/engine/swarm/secrets/](https://docs.docker.com/engine/swarm/secrets/).



Currently, the following environment variables

```

 GEOSERVER_ADMIN_USER

 GEOSERVER_ADMIN_PASSWORD

 S3_USERNAME

 S3_PASSWORD

 S3_SERVER_URL

 S3_ALIAS

 TOMCAT_USER

 TOMCAT_PASSWORD

 PKCS12_PASSWORD

 JKS_KEY_PASSWORD

 JKS_STORE_PASSWORD

 TOMCAT_USER

```

are supported.



### Changing GeoServer deployment context-root



You can pass the environment variable to change the context-root at runtime,

example:

```

GEOSERVER_CONTEXT_ROOT=my-geoserver

```



The example above will deploy Geoserver at https://host/my-geoserver instead of

the default location at https://host/geoserver.



It is also possible to do a nested context-root. [Apache Tomcat nested 

context-roots are specified via #](https://octopus.com/blog/defining-tomcat-context-paths#conclusion).

```

GEOSERVER_CONTEXT_ROOT=foo#my-geoserver

```

The example above will deploy Geoserver at https://host/foo/my-geoserver 

instead of the default location at https://host/geoserver.



## Mounting Configs



You can mount the config file to the path `/settings`. These configs will

be used in favour of the defaults that are available from the [Build data](https://github.com/kartoza/docker-geoserver/tree/master/build_data)

directory



The configs that can be mounted are

* cluster.properties

* controlflow.properties

* embedded-broker.properties

* geowebcache-diskquota-jdbc.xml

* s3.properties

* tomcat-users.xml

* web.xml - for tomcat cors

* epsg.properties - for custom GeoServer EPSG values

* server.xml - for tomcat configurations

* broker.xml

* users.xml - for Geoserver users.

* roles.xml - To define roles users should have in GeoServer

* logging.properties - Controls logging to sdtout parameters



Example

```

 docker run --name "geoserver" -e GEOSERVER_ADMIN_USER=kartoza  -v /data/controlflow.properties:/settings/controlflow.properties -p 8080:8080 -d -t kartoza/geoserver

```



**Note:** The files `users.xml` and `roles.xml` should be mounted together to prevent errors

during container start. Mounting these two files will overwrite `GEOSERVER_ADMIN_PASSWORD` and `GEOSERVER_ADMIN_USER`



### Running scripts on container startup.



You can run some bash script to correct some missing dependencies i.e. in 

community extension like [cluster issue](https://github.com/kartoza/docker-geoserver/issues/514)



```bash

-v ./run.sh:/docker-entrypoint-geoserver.d/run.sh

```



### CORS Support



The image ships with CORS support. If you however need to modify the web.xml you

can mount `web.xml` to `/settings/` directory.



## Clustering GeoServer



### JMS Clustering



GeoServer supports clustering using the JMS cluster plugin.



You can read more about how to set up clustering in [kartoza clustering](https://github.com/kartoza/docker-geoserver/blob/master/clustering/README.md)



### ActiveMQ-broker



You can use the `docker-compose-external.yml` in the clustering folder.



## Running the Image



### Run (automated using docker-compose)



We provide a sample ``docker-compose.yml`` file that illustrates

how you can establish a GeoServer + PostGIS.



If you are interested in the backups, add a section in the `docker-compose.yml`

following instructions from [docker-pg-backup](https://github.com/kartoza/docker-pg-backup/blob/master/docker-compose.yml#L23).



Start the services using:

``` shell

docker-compose up -d

```



**Note** The username and password are specified in the `.env` file. It is recommended

to change them into something more secure. If you do not pass the

env `GEOSERVER_ADMIN_PASSWORD` the container generates a 

random string which will be your password. This is visible from 

the startup logs.



Once all the services start, test by visiting the GeoServer landing

page in your browser: [http://localhost:8600/geoserver](http://localhost:8600/geoserver).



### Reverse Proxy using NGINX



You can also put Nginx in front of GeoServer to receive the http request and translate it to uwsgi.



A sample `docker-compose-nginx.yml` is provided for running GeoServer and Nginx



``` shell

docker-compose -f docker-compose-nginx.yml  up -d

```

Once the services are running GeoServer will be available from



http://localhost/geoserver/web/



## Kubernetes (Helm Charts)



You can run the image in Kubernetes following the [recipe](https://github.com/kartoza/charts/tree/develop/charts/geoserver)



## Contributing to the image

We welcome users who want to contribute to enriching this service. We follow

the git principles and all pull requests should be against the develop branch so that

we can test them and when we are happy we push them to the master branch.



### Upgrading GeoServer Versions

GeoServer releases and bug fixes are done frequently. We provide a helper script 

`upgrade_geoserver_version.sh` which can be run to update the 

respective files which mention the GeoServer version. To upgrade to

a new version involves:



1. Run the upgrade script that updates some env variables.

2. Update the [github workflows](https://github.com/kartoza/docker-geoserver/tree/develop/.github/workflows) files to.

match the specific versions.



#### Run upgrade helper script



```bash

/bin/bash upgrade_geoserver_version.sh ${GS_VERSION} ${GS_NEW_VERSION}

```

**Note:** The script will also push these changes to the current repo, and it is up to the individual running the script

to push the changes to his specific branch of choice and then complete the pull request



## Support
