ejabberd Container
|
|
==================
|
|
|
|
[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 images](https://github.com/processone/ejabberd/pkgs/container/ejabberd)
|
|
available in the GitHub Container Registry,
|
|
built using the files in `.github/container/`.
|
|
|
|
Alternatively, there are also
|
|
[ejabberd-ecs Docker images](https://hub.docker.com/r/ejabberd/ecs/)
|
|
available in Docker Hub,
|
|
built using the
|
|
[docker-ejabberd/ecs](https://github.com/processone/docker-ejabberd/tree/master/ecs)
|
|
repository.
|
|
|
|
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 the required options:
|
|
```
|
|
captcha_cmd: /opt/ejabberd-22.04/lib/ejabberd-22.04/priv/bin/captcha.sh
|
|
captcha_url: https://localhost:5443/captcha
|
|
```
|
|
|
|
Finally, reload the configuration file or restart the container:
|
|
```bash
|
|
docker exec ejabberd ejabberdctl reload_config
|
|
```
|
|
|
|
|
|
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
|
|
|
|
|
|
### 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 docker 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 (see full example [docker-compose.yml](https://github.com/processone/docker-ejabberd/issues/64#issuecomment-887741332)):
|
|
```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 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
|
|
```
|
|
|
|
|
|
Generating 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
|
|
|
|
Build ejabberd Community Server base image from ejabberd master on GitHub:
|
|
|
|
```bash
|
|
VERSION = master
|
|
docker build \
|
|
--build-arg VERSION=$(VERSION) \
|
|
-t personal/ejabberd:$(VERSION) \
|
|
.github/container
|
|
```
|
|
|
|
Build ejabberd Community Server base image for a given ejabberd version,
|
|
both for amd64 and arm64 architectures:
|
|
|
|
```bash
|
|
VERSION = 22.05
|
|
docker buildx build \
|
|
--platform=linux/amd64,linux/arm64
|
|
--build-arg VERSION=$(VERSION) \
|
|
-t personal/ejabberd:$(VERSION) \
|
|
.github/container
|
|
```
|
|
|
|
It's also possible to use podman instead of docker, just notice:
|
|
- `EXPOSE 4369-4399` port range is not supported, remove that in Dockerfile
|
|
- It mentions that `healthcheck` is not supported by the Open Container Initiative image format
|
|
- If you want to start with command `live`, add environment variable `EJABBERD_BYPASS_WARNINGS=true`
|
|
```bash
|
|
VERSION = master
|
|
podman build \
|
|
--build-arg VERSION=$(VERSION) \
|
|
-t ja:$(version) \
|
|
.github/container
|
|
```
