`ejabberd` Container Image
|
|
==========================
|
|
|
|
[ejabberd][home] is an open-source,
|
|
robust, scalable and extensible realtime platform built using [Erlang/OTP][erlang],
|
|
that includes [XMPP][xmpp] Server, [MQTT][mqtt] Broker and [SIP][sip] Service.

This document explains how to use the `ejabberd` container image available in
|
|
[ghcr.io/processone/ejabberd](https://github.com/processone/ejabberd/pkgs/container/ejabberd),
|
|
built using the files in `.github/container/`.
|
|
This image is based in Alpine 3.17, includes Erlang/OTP 25.3 and Elixir 1.14.4.
|
|
|
|
Alternatively, there is also the `ecs` container image available in
|
|
[docker.io/ejabberd/ecs](https://hub.docker.com/r/ejabberd/ecs/),
|
|
built using the
|
|
[docker-ejabberd/ecs](https://github.com/processone/docker-ejabberd/tree/master/ecs)
|
|
repository.
|
|
Check the [differences between `ejabberd` and `ecs` images](https://github.com/processone/docker-ejabberd/blob/master/ecs/HUB-README.md#alternative-image-in-github).
|
|

|
If you are using a Windows operating system, check the tutorials mentioned in
|
|
[ejabberd Docs > Docker Image](https://docs.ejabberd.im/admin/installation/#docker-image).
|
|
|
|
|
|
Start ejabberd
|
|
==============
|
|
|
|
## With default configuration
|
|
|
|
Start ejabberd in a new container:
|
|
|
|
```bash
|
|
docker run --name ejabberd -d -p 5222:5222 ghcr.io/processone/ejabberd
|
|
```
|
|
|
|
That runs the container as a daemon,
|
|
using ejabberd default configuration file and XMPP domain "localhost".
|
|
|
|
Stop the running container:
|
|
|
|
```bash
|
|
docker stop ejabberd
|
|
```
|
|
|
|
Restart the stopped ejabberd container:
|
|
|
|
```bash
|
|
docker restart ejabberd
|
|
```
|
|
|
|
|
|
## Start with Erlang console attached
|
|
|
|
Start ejabberd with an Erlang console attached using the `live` command:
|
|
|
|
```bash
|
|
docker run --name ejabberd -it -p 5222:5222 ghcr.io/processone/ejabberd live
|
|
```
|
|
|
|
That uses the default configuration file and XMPP domain "localhost".
|
|
|
|
|
|
## Start with your configuration and database
|
|
|
|
Pass a configuration file as a volume
|
|
and share the local directory to store database:
|
|
|
|
```bash
|
|
mkdir database
|
|
chown ejabberd database
|
|
|
|
cp ejabberd.yml.example ejabberd.yml
|
|
|
|
docker run --name ejabberd -it \
|
|
-v $(pwd)/ejabberd.yml:/opt/ejabberd/conf/ejabberd.yml \
|
|
-v $(pwd)/database:/opt/ejabberd/database \
|
|
-p 5222:5222 ghcr.io/processone/ejabberd live
|
|
```
|
|
|
|
Notice that ejabberd runs in the container with an account named `ejabberd`,
|
|
and the volumes you mount must grant proper rights to that account.
|
|
|
|
|
|
Next steps
|
|
==========
|
|
|
|
## Register the administrator account
|
|
|
|
The default ejabberd configuration does not grant admin privileges
|
|
to any account,
|
|
you may want to register a new account in ejabberd
|
|
and grant it admin rights.
|
|
|
|
Register an account using the `ejabberdctl` script:
|
|
|
|
```bash
|
|
docker exec -it ejabberd ejabberdctl register admin localhost passw0rd
|
|
```
|
|
|
|
Then edit conf/ejabberd.yml and add the ACL as explained in
|
|
[ejabberd Docs: Administration Account](https://docs.ejabberd.im/admin/installation/#administration-account)
|
|
|
|
|
|
## Check ejabberd log files
|
|
|
|
Check the content of the log files inside the container,
|
|
even if you do not put it on a shared persistent drive:
|
|
|
|
```bash
|
|
docker exec -it ejabberd tail -f logs/ejabberd.log
|
|
```
|
|
|
|
|
|
## Inspect the container files
|
|
|
|
The container uses Alpine Linux. Start a shell inside the container:
|
|
|
|
```bash
|
|
docker exec -it ejabberd sh
|
|
```
|
|
|
|
|
|
## Open ejabberd debug console
|
|
|
|
Open an interactive debug Erlang console attached to a running ejabberd in a running container:
|
|
|
|
```bash
|
|
docker exec -it ejabberd ejabberdctl debug
|
|
```
|
|
|
|
|
|
## CAPTCHA
|
|
|
|
ejabberd includes two example CAPTCHA scripts.
|
|
If you want to use any of them, first install some additional required libraries:
|
|
|
|
```bash
|
|
docker exec --user root ejabberd apk add imagemagick ghostscript-fonts bash
|
|
```
|
|
|
|
Now update your ejabberd configuration file, for example:
|
|
```bash
|
|
docker exec -it ejabberd vi conf/ejabberd.yml
|
|
```
|
|
|
|
and add this option:
|
|
```yaml
|
|
captcha_cmd: /opt/ejabberd-22.04/lib/captcha.sh
|
|
```
|
|
|
|
Finally, reload the configuration file or restart the container:
|
|
```bash
|
|
docker exec ejabberd ejabberdctl reload_config
|
|
```
|
|
|
|
If the CAPTCHA image is not visible, there may be a problem generating it
|
|
(the ejabberd log file may show some error message);
|
|
or the image URL may not be correctly detected by ejabberd,
|
|
in that case you can set the correct URL manually, for example:
|
|
```yaml
|
|
captcha_url: https://localhost:5443/captcha
|
|
```
|
|
|
|
For more details about CAPTCHA options, please check the
|
|
[CAPTCHA](https://docs.ejabberd.im/admin/configuration/basic/#captcha)
|
|
documentation section.

|
|
Advanced Container Configuration
|
|
================================
|
|
|
|
## Ports
|
|
|
|
This container image exposes the ports:
|
|
|
|
- `5222`: The default port for XMPP clients.
|
|
- `5269`: For XMPP federation. Only needed if you want to communicate with users on other servers.
|
|
- `5280`: For admin interface.
|
|
- `5443`: With encryption, used for admin interface, API, CAPTCHA, OAuth, Websockets and XMPP BOSH.
|
|
- `1883`: Used for MQTT
|
|
- `4369-4399`: EPMD and Erlang connectivity, used for `ejabberdctl` and clustering
|
|
- `5210`: Erlang connectivity when `ERL_DIST_PORT` is set, alternative to EPMD
|
|
|
|
|
|
## Volumes
|
|
|
|
ejabberd produces two types of data: log files and database spool files (Mnesia).
|
|
This is the kind of data you probably want to store on a persistent or local drive (at least the database).
|
|
|
|
The volumes you may want to map:
|
|
|
|
- `/opt/ejabberd/conf/`: Directory containing configuration and certificates
|
|
- `/opt/ejabberd/database/`: Directory containing Mnesia database.
|
|
You should back up or export the content of the directory to persistent storage
|
|
(host storage, local storage, any storage plugin)
|
|
- `/opt/ejabberd/logs/`: Directory containing log files
|
|
- `/opt/ejabberd/upload/`: Directory containing uploaded files. This should also be backed up.
|
|
|
|
All these files are owned by `ejabberd` user inside the container.
|
|
|
|
It's possible to install additional ejabberd modules using volumes,
|
|
[this comment](https://github.com/processone/docker-ejabberd/issues/81#issuecomment-1036115146)
|
|
explains how to install an additional module using docker-compose.
|
|
|
|
|
|
## Commands on start
|
|
|
|
The ejabberdctl script reads the `CTL_ON_CREATE` environment variable
|
|
the first time the container is started,
|
|
and reads `CTL_ON_START` every time the container is started.
|
|
Those variables can contain one ejabberdctl command,
|
|
or several commands separated with the blankspace and `;` characters.
|
|
|
|
Example usage (or check the [full example](#customized-example)):
|
|
```yaml
|
|
environment:
|
|
- CTL_ON_CREATE=register admin localhost asd
|
|
- CTL_ON_START=stats registeredusers ;
|
|
check_password admin localhost asd ;
|
|
status
|
|
```
|
|
|
|
|
|
## Clustering
|
|
|
|
When setting several containers to form a
|
|
[cluster of ejabberd nodes](https://docs.ejabberd.im/admin/guide/clustering/),
|
|
each one must have a different
|
|
[Erlang Node Name](https://docs.ejabberd.im/admin/guide/security/#erlang-node-name)
|
|
and the same
|
|
[Erlang Cookie](https://docs.ejabberd.im/admin/guide/security/#erlang-cookie).
|
|
|
|
For this you can either:
|
|
- edit `conf/ejabberdctl.cfg` and set variables `ERLANG_NODE` and `ERLANG_COOKIE`
|
|
- set the environment variables `ERLANG_NODE_ARG` and `ERLANG_COOKIE`
|
|
|
|
Example to connect a local `ejabberdctl` to a containerized ejabberd:
|
|
1. When creating the container, export port 5210, and set `ERLANG_COOKIE`:
|
|
```
|
|
docker run --name ejabberd -it \
|
|
-e ERLANG_COOKIE=`cat $HOME/.erlang.cookie` \
|
|
-p 5210:5210 -p 5222:5222 \
|
|
ghcr.io/processone/ejabberd
|
|
```
|
|
2. Set `ERL_DIST_PORT=5210` in ejabberdctl.cfg of container and local ejabberd
|
|
3. Restart the container
|
|
4. Now use `ejabberdctl` in your local ejabberd deployment
|
|
|
|
To connect using a local `ejabberd` script:
|
|
```
|
|
ERL_DIST_PORT=5210 _build/dev/rel/ejabberd/bin/ejabberd ping
|
|
```
|
|
|
|
Example using environment variables (see full example [docker-compose.yml](https://github.com/processone/docker-ejabberd/issues/64#issuecomment-887741332)):
|
|
```yaml
|
|
environment:
|
|
- ERLANG_NODE_ARG=ejabberd@node7
|
|
- ERLANG_COOKIE=dummycookie123
|
|
```
|
|
|
|
|
|
Build a Container Image
|
|
=======================
|
|
|
|
This container image includes ejabberd as a standalone OTP release built using Elixir.
|
|
That OTP release is configured with:
|
|
|
|
- `mix.exs`: Customize ejabberd release
|
|
- `vars.config`: ejabberd compilation configuration options
|
|
- `config/runtime.exs`: Customize ejabberd paths
|
|
- `ejabberd.yml.template`: ejabberd default config file
|
|
|
|
## Direct build
|
|
|
|
Build ejabberd Community Server container image from ejabberd master git repository:
|
|
|
|
```bash
|
|
docker buildx build \
|
|
-t personal/ejabberd \
|
|
-f .github/container/Dockerfile \
|
|
.
|
|
```
|
|
|
|
## Podman build
|
|
|
|
It's also possible to use podman instead of docker, just notice:
|
|
- `EXPOSE 4369-4399` port range is not supported, remove that in Dockerfile
|
|
- It mentions that `healthcheck` is not supported by the Open Container Initiative image format
|
|
- If you want to start with command `live`, add environment variable `EJABBERD_BYPASS_WARNINGS=true`
|
|
```bash
|
|
podman build \
|
|
-t ejabberd \
|
|
-f .github/container/Dockerfile \
|
|
.
|
|
|
|
podman run --name eja1 -d -p 5222:5222 localhost/ejabberd
|
|
|
|
podman exec eja1 ejabberdctl status
|
|
|
|
podman exec -it eja1 sh
|
|
|
|
podman stop eja1
|
|
```
|
|
|
|
## Package build for `arm64`
|
|
|
|
By default, `.github/container/Dockerfile` builds this container by directly compiling ejabberd,
|
|
it is a fast and direct method.
|
|
However, a problem with QEMU prevents building the container in QEMU using Erlang/OTP 25
|
|
for the `arm64` architecture.
|
|
|
|
Providing `--build-arg METHOD=package` is an alternate method to build the container
|
|
used by the Github Actions workflow that provides `amd64` and `arm64` container images.
|
|
It first builds an ejabberd binary package, and later installs it in the image.
|
|
That method avoids using QEMU, so it can build `arm64` container images, but is extremely
|
|
slow the first time it's used, and consequently not recommended for general use.
|
|
|
|
In this case, to build the ejabberd container image for arm64 architecture:
|
|
|
|
```bash
|
|
docker buildx build \
|
|
--build-arg METHOD=package \
|
|
--platform linux/arm64 \
|
|
-t personal/ejabberd:$VERSION \
|
|
-f .github/container/Dockerfile \
|
|
.
|
|
```
|
|
|
|
|
|
Composer Examples
|
|
=================
|
|
|
|
## Minimal Example
|
|
|
|
This is the barely minimal file to get a usable ejabberd.
|
|
Store it as `docker-compose.yml`:
|
|
|
|
```yaml
|
|
services:
|
|
main:
|
|
image: ghcr.io/processone/ejabberd
|
|
container_name: ejabberd
|
|
ports:
|
|
- "5222:5222"
|
|
- "5269:5269"
|
|
- "5280:5280"
|
|
- "5443:5443"
|
|
```
|
|
|
|
Create and start the container with the command:
|
|
```bash
|
|
docker-compose up
|
|
```
|
|
|
|
## Customized Example
|
|
|
|
This example shows the usage of several customizations:
|
|
it uses a local configuration file,
|
|
stores the mnesia database in a local path,
|
|
registers an account when it's created,
|
|
and checks the number of registered accounts every time it's started.
|
|
|
|
Download or copy the ejabberd configuration file:
|
|
```bash
|
|
wget https://raw.githubusercontent.com/processone/ejabberd/master/ejabberd.yml.example
|
|
mv ejabberd.yml.example ejabberd.yml
|
|
```
|
|
|
|
Create the database directory and allow the container access to it:
|
|
```bash
|
|
mkdir database
|
|
sudo chown 9000:9000 database
|
|
```
|
|
|
|
Now write this `docker-compose.yml` file:
|
|
```yaml
|
|
version: '3.7'
|
|
|
|
services:
|
|
|
|
main:
|
|
image: ghcr.io/processone/ejabberd
|
|
container_name: ejabberd
|
|
environment:
|
|
- CTL_ON_CREATE=register admin localhost asd
|
|
- CTL_ON_START=registered_users localhost ;
|
|
status
|
|
ports:
|
|
- "5222:5222"
|
|
- "5269:5269"
|
|
- "5280:5280"
|
|
- "5443:5443"
|
|
volumes:
|
|
- ./ejabberd.yml:/opt/ejabberd/conf/ejabberd.yml:ro
|
|
- ./database:/opt/ejabberd/database
|
|
```
|
|
|
|
## Clustering Example
|
|
|
|
In this example, the main container is created first.
|
|
Once it is fully started and healthy, a second container is created,
|
|
and once ejabberd is started in it, it joins the first one.
|
|
|
|
An account is registered in the first node when created,
|
|
and it should exist in the second node after join.
|
|
|
|
Notice that in this example the main container does not have access
|
|
to the exterior; the replica exports the ports and can be accessed.
|
|
|
|
```yaml
|
|
version: '3.7'
|
|
|
|
services:
|
|
|
|
main:
|
|
image: ghcr.io/processone/ejabberd
|
|
container_name: ejabberd
|
|
environment:
|
|
- ERLANG_NODE_ARG=ejabberd@main
|
|
- ERLANG_COOKIE=dummycookie123
|
|
- CTL_ON_CREATE=register admin localhost asd
|
|
|
|
replica:
|
|
image: ghcr.io/processone/ejabberd
|
|
container_name: replica
|
|
depends_on:
|
|
main:
|
|
condition: service_healthy
|
|
ports:
|
|
- "5222:5222"
|
|
- "5269:5269"
|
|
- "5280:5280"
|
|
- "5443:5443"
|
|
environment:
|
|
- ERLANG_NODE_ARG=ejabberd@replica
|
|
- ERLANG_COOKIE=dummycookie123
|
|
- CTL_ON_CREATE=join_cluster ejabberd@main
|
|
- CTL_ON_START=registered_users localhost ;
|
|
status
|
|
```
|
