## ejabberd Community Edition - Base
This ejabberd Docker image allows you to run a single node ejabberd instance in a Docker container.
## Running ejabberd
### Default configuration for domain localhost
You can run ejabberd with the following command:
```bash
docker run -it -p 5222:5222 ejabberd/ecs
```
This command will use default configuration file and XMPP domain "localhost".
### Running ejabberd with your config file and database host directory
```bash
mkdir db
docker run --rm -it -v $(pwd)/db:/home/p1/db -p 5222:5222 ejabberd/ecs
```
## Docker configuration
### Files
Here are the important files you can replace by mounting persistent disk or local directory:
- /home/p1/cfg/ejabberd.yml: ejabberd configuration file.
### Ports
ejabberd base Docker image exposes the following port:
- 5222: This is the default XMPP port for clients.
- 5280: This is the port for admin interface, API, Websockets and XMPP BOSH.
- 5269: Optional. This is the port for XMPP federation. Only needed if you want
to communicate with users on other servers.
### Volumes
ejabberd produces two type of data: log files and database (Mnesia).
This is the kind of data you probably want to store on a persistent or local drive (at least the database).
Here are the volume you may want to map:
- /home/p1/log/: Directory containing log files
- /home/p1/db/: Directory containing Mnesia database. You should backup or
export the content of the directory to persistent storage (host storage, local storage, any storage plugin)
## Generating ejabberd release
### Configuration
Configuration of ejabberd release is customized with:
- rel/config.exs: Customize ejabberd release
- rel/dev.exs: ejabberd environment configuration for development release
- rel/docker.exs: ejabberd environment configuration for production Docker release
- ejabberd.yml: ejabberd default config file
Run the build script to generate ejabberd ecs base image from ejabberd master on Github:
```bash
./build.sh
```
### TODO
- Embed command-line tool for ejabberd API to be able to create admin user for ejabberd.
