Thanks for using!
# Docker image for ejabberd xmpp server
This is a multi-arch [ejabberd](https://docs.ejabberd.im/ "ejabberd") docker image, currently built for
* linux/amd64
* linux/386
* linux/arm64
* linux/arm/v7
* linux/arm/v6
and based on Alpine Linux. It contains a startup configuration script and an option for kubernetes to perform automatic clustering.
The image itself is now based upon the [official ejabberd docker image](https://github.com/processone/ejabberd/blob/master/.github/container/Dockerfile) since the recent improvements of that image. It only contains small differences, mainly to reduce the # of layers, and, of course, to include the configuration script into the running process.
**Please also look for breaking changes in the [release descriptions](https://github.com/sando38/docker-ejabberd-multiarch/releases)!**
[Docker Hub link](https://hub.docker.com/r/sando38/docker-ejabberd-multiarch)
There may be further architectures supported in future. If you need another, raise an issue on github.
## Usage
In the current setup, the image provides a default ejabberd configuration file, which will provide a running server at localhost. However, it is strongly advised to tune the configuration file. This may be achieved in two ways:
* using various environment variables like described below,
* providing/ mounting own configuration file(s)
To pull the image, just refer to the Docker Hub repository:
docker pull sando38/docker-ejabberd-multiarch
The image will run in ejabberd foreground mode, if started this way:
docker run --rm -d --name ejabberd -p 5222:5222 -p 5443:5443 sando38/docker-ejabberd-multiarch
The image can also run in an unprivileged mode:
```
docker run --rm -d \
--name ejabberd \
--user 9000:9000 \
--security-opt no-new-privileges \
--cap-drop=ALL \
--read-only \
-p 5222:5222 \
-p 5443:5443 \
sando38/docker-ejabberd-multiarch
```
Inspect the running container with
`docker logs < container name >`
## Kubernetes auto clustering
The image has experimental kubernetes auto clustering support. The variables `ERLANG_COOKIE` and `KUBERNETES_AUTO_CLUSTER` must be defined for that.
Furthermore, this feature needs a statefulset combined with a headless service to function. A `kustomize` configuration example is provided in this repository. A helm chart may follow in the near future.
The kustomize example is not ready to use and must be adjusted to your needs, i.e. PVCs for ejabberd nodes, TLS certificates mounted as generic secrets. A PVC for `HTTP Upload` and `HTTP File Server` should be considered as a `ReadWriteMany` type.
Furthermore, the kustomize example assumes a reverse proxy in front of ejabberd. The example provides traefik proxy services. This also needs to be adjusted to your needs.
## Tags
`XX-YY` represents the official ejabberd release, `-vX.Y.Z` is the version of the Docker image, which rises in number, e.g. due to bug fixes, enhancements, etc.
For CAPTCHA, please use the suffix `-captcha`.
| TAGS | Description | Additional notes |
| ------------ | ------------ | ------------ |
| `latest`, `22.05-v3.1.2` | [offical ejabberd release notes](https://www.process-one.net/blog/ejabberd-22-05/), changes see [image release notes](https://github.com/sando38/docker-ejabberd-multiarch/releases/tag/v3.1.2) | |
| `latest-captcha`, `22.05-v3.1.2-captcha` | like above | plus additional packages `bash ghostscript-fonts imagemagick` needed for CAPTCHA |
## Configure the image
This image provides a way to adjust the standard configuration file `ejabberd.yml` at initial startup. If the configuration file is not made persistent (e.g. via a mounted volume), the configuration file will be (re)created at every startup. The configuration file will not be configured, if one provides an own `ejabberd.yml` file and mounts it into the container.
**Mountpath:**
` -v /path/to/ejabberd.yml:/opt/ejabberd/conf/ejabberd.yml`
[Link to ejabberd.yml example file](https://github.com/processone/ejabberd/blob/master/ejabberd.yml.example "Link to ejabberd.yml example file")
## Volume mounts
It is advised to make some data persistent. Those can be mounted here:
```
volumes:
- /path/to/config-files:/opt/ejabberd/conf # for (custom) configuration files
- /path/to/database:/opt/ejabberd/database # mnesia database & acme client certificates
- /path/to/fileserver/docs:/opt/ejabberd/files # for HTTP fileserver functionality
- /path/to/cert-files:/opt/ejabberd/tls # for custom tls certicates
- /path/to/upload/files:/opt/ejabberd/upload # for HTTP upload functionality
```
NOTE: if you mount a docker volume for the configuration files, those will be persistent and the startup script is not going to be applied at next startup. Therefore, manual changes must occur within the docker volume and the respective configuration files.
TLS certificates must be owned by ejabberd user/ group `9000:9000` and should not have world readable access rights.
To trigger the startup script, at least the file `ejabberd.yml` must be deleted/ renamed from the docker volume.
## Parameters to configure ejabberd
If the default column is empty, then there is no default.
Parameters in **bold** can be adjusted according to [ejabberd docs](https://docs.ejabberd.im/admin/configuration/ "ejabberd docs"). The Parameters may have a slightly different naming.

This is especially important in conjunction with [mod_fail2ban](https://docs.ejabberd.im/admin/configuration/modules/#mod-fail2ban). | false |
| | | |
#### Client to Server connections (TLS)
For legacy TLS connections. This may be interesting also to map via port 443, either behind a layer4 load balancer or directly with e.g. an iptables rule, since ejabberd cannot listen to 443 (privileged ports) directly.

| | | |
#### STUN-TURN listener
ejabberd offers a STUN-TURN listener. In a docker environment, TURN service may be problematic, because docker is not handling large port ranges well, which would be required by the TURN feature. More information [here](https://docs.ejabberd.im/admin/configuration/listen/#ejabberd-stun-1).
Additinally, it is advised to also set SRV records for the XMPP domains in the domains' DNS server.
Please note: STUN-TURN listener does not support HAproxy Protocol as of now (ejabberd-v21-12).

### Core modules addressed by the startup script of this image
These is a list of modules addressed by the startup script. For some it may be advised to mount an own configuration script at the following path:
`-v /path/to/module/configuration/files:/opt/ejabberd/conf`
A general description of modules options can be found here: [Ejabberd docs](https://docs.ejabberd.im/admin/configuration/modules/).
Some modules will only be enabled if the respective listener is active (e.g. mod_bosh, mod_conversejs mod_http_api, etc.)
Some modules depend on other modules to be anabled. For example, mod_avatar depends on mod_pubsub, mod_vcard and mod_vcard_xupdate.

### Additional modules
Activation of additional core modules. No configuration file will be generated by the startup script, therefore, they must be mounted into the following path:
`-v /path/to/module/configuration/files:/opt/ejabberd/conf`
To activate the module `mod_http_upload_quota`, e.g. the parameter `ADDITIONAL_CORE_MODULE_1_NAME=mod_http_upload_quota` is set and the configfile `mod_http_upload_quota.yml` is mounted.
| Parameter | Description | Default |
| ------------ | ------------ | ------------ |
| ADDITIONAL_CORE_MODULE_1_NAME | If parameter is set, then module will be added to the configuration file. To make it function, a module configuration file must be mounted at the mentioned path above with the the following name: `$ADDITIONAL_CORE_MODULE_1_NAME.yml` , e.g. `mod_http_upload_quota.yml` | |
| ADDITIONAL_CORE_MODULE_2_NAME | If parameter is set, then module will be added to the configuration file. To make it function, a module configuration file must be mounted at the mentioned path above with the the following name: `$ADDITIONAL_CORE_MODULE_2_NAME.yml` , e.g. `mod_metrics.yml` | |
| ADDITIONAL_CORE_MODULE_3_NAME | If parameter is set, then module will be added to the configuration file. To make it function, a module configuration file must be mounted at the mentioned path above with the the following name: `$ADDITIONAL_CORE_MODULE_3_NAME.yml` , e.g. `mod_shared_roster_ldap.yml` | |
| | | |
Currently three additional modules (configurations) may be enabled. Practically, however, a configuration file can include more than one module, e.g. a configuration could look like this for an example config file `additional-modules.yml`:
```
modules:
mod_http_upload_quota:
max_days: 30
mod_metrics:
ip: 127.0.0.1
port: 11111
```
This would activate two modules with only using one parameter (e.g. `ADDITIONAL_CORE_MODULE_1_NAME=additional-modules`)
### Load new modules from ejabberd contributions
Furthermore, the startup script can load additional modules from [ejabberd contributions](https://github.com/processone/ejabberd-contrib). No configuration file will be generated by the startup script, therefore, they must be mounted into the following path:
`-v /path/to/module/configuration/files:/opt/ejabberd/conf`
To activate the ejabberd contributions module `mod_cron`, e.g. the parameter `INSTALL_ADDITIONAL_NON_CORE_MODULE_1_NAME=mod_cron` is set and the configfile `mod_cron.yml` is mounted.
NOTE: if you use/ mount a custom `ejabberd.yml`, the ejabberd contribution modules must not be referenced in the `ejabberd.yml`.
| Parameter | Description | Default |
| ------------ | ------------ | ------------ |
| INSTALL_ADDITIONAL_NON_CORE_MODULE_1_NAME | If parameter is set, then module will be added to the configuration file. To make it function, a module configuration file must be mounted at the mentioned path above with the the following name: `$INSTALL_ADDITIONAL_NON_CORE_MODULE_1_NAME.yml` , e.g. `mod_cron.yml` | |
| INSTALL_ADDITIONAL_NON_CORE_MODULE_2_NAME | If parameter is set, then module will be added to the configuration file. To make it function, a module configuration file must be mounted at the mentioned path above with the the following name: `$INSTALL_ADDITIONAL_NON_CORE_MODULE_2_NAME.yml` , e.g. `mod_default_contacts.yml` | |
| INSTALL_ADDITIONAL_NON_CORE_MODULE_3_NAME | If parameter is set, then module will be added to the configuration file. To make it function, a module configuration file must be mounted at the mentioned path above with the the following name: `$INSTALL_ADDITIONAL_NON_CORE_MODULE_3_NAME.yml` , e.g. `mod_default_rooms.yml` | |
| | | |
Currently three additional contributions modules can be added to the script.
