This Docker images provides the [ejabberd](https://www.ejabberd.im/) as an development image
with the mDNS/ZeroConf stack on top. So you can enjoy the ejabberd service
while it is accessible by default as *ejabberd.local*.
**Heads up!** This image is dedicated to your development environment.
Do not run it on production!

## Requirements
* Host enabled Avahi daemon
* Host enabled mDNS NSS lookup
## Getting starting
You just need to run it like that, to get a working ejabberd service:
```bash
$ docker run --rm hausgold/ejabberd
```
The port 5280 is proxied by haproxy to port 80 to make *ejabberd.local*
directly accessible. So you can use the HTTP WebSockets
(*ejabberd.local/websocket*) and Admin panel (*ejabberd.local/admin*)
directly.
The admin user is **admin@MDNS_HOSTNAME**, so by default it is
`admin@ejabberd.local` with the password `defaultpw`.
## docker-compose usage example
```yaml
services:
ejabberd:
image: hausgold/ejabberd
environment:
# Mind the .local suffix
MDNS_HOSTNAME: ejabberd.test.local
```
## Host configs
Install the nss-mdns package, enable and start the avahi-daemon.service. Then,
edit the file /etc/nsswitch.conf and change the hosts line like this:
```bash
hosts: ... mdns4_minimal [NOTFOUND=return] resolve [!UNAVAIL=return] dns ...
```
## Configure a different mDNS hostname
The magic environment variable is *MDNS_HOSTNAME*. Just pass it like that to
your docker run command:
```bash
$ docker run --rm -e MDNS_HOSTNAME=something.else.local hausgold/ejabberd
```
This will result in *something.else.local*.
You can also configure multiple aliases (CNAME's) for your container by
passing the *MDNS_CNAMES* environment variable. It will register all the comma
separated domains as aliases for the container, next to the regular mDNS
hostname.
```bash
$ docker run --rm \
-e MDNS_HOSTNAME=something.else.local \
-e MDNS_CNAMES=nothing.else.local,special.local \
hausgold/ejabberd
```
This will result in *something.else.local*, *nothing.else.local* and
*special.local*.
## Other top level domains
By default *.local* is the default mDNS top level domain. This images does not
force you to use it. But if you do not use the default *.local* top level
domain, you need to [configure your host avahi][custom_mdns] to accept it.
