Introduction

Dockerfile to create a Docker container image for Openfire.

Openfire is a real time collaboration (RTC) server licensed under the Open Source Apache License. It uses the only widely adopted open protocol for instant messaging, XMPP (also called Jabber). Openfire is incredibly easy to setup and administer, but offers rock-solid security and performance.

This image will be updated from Openfire version 4.2.3 up to newer versions.

Getting started

Image Pull

docker pull credija/openfire:lts

Quickstart

Start Openfire using:

docker run --name openfire-credija -d --restart=always \
  --publish 9090:9090 --publish 5222:5222 --publish 7777:7777 \
  --publish 7070:7070 --publish 7443:7443 \
  --volume /opt/your-persistent-folder:/var/lib/openfire \
  -m 2GB \
  credija/openfire:lts \
  -XX:+UnlockExperimentalVMOptions \
  -XX:+UseCGroupMemoryLimitForHeap

Alternatively, you can use the sample docker-compose.yml file to start the container using Docker Compose

Point your browser to http://localhost:9090 and follow the setup procedure to complete the installation.

Persistence

For the Openfire to preserve its state across container shutdown and startup you should mount a volume at /var/lib/openfire.

The Quickstart command already mounts a volume for persistence.

SELinux users should update the security context of the host mountpoint so that it plays nicely with Docker:

mkdir -p /srv/docker/openfire
chcon -Rt svirt_sandbox_file_t /srv/docker/openfire

Java VM options

You may append options to the startup command to configure the JVM:

docker run --name openfire-credija -d --restart=always \
  --publish 9090:9090 --publish 5222:5222 --publish 7777:7777 --publish 7070:7070 --publish 7443:7443 \
  --volume /opt/your-persistent-folder:/var/lib/openfire \
  -m 2GB \
  credija/openfire:lts \
  -XX:+UnlockExperimentalVMOptions \
  -XX:+UseCGroupMemoryLimitForHeap

Logs

To access the Openfire logs, located at /var/log/openfire, you can use docker exec. For example, if you want to tail the logs:

docker exec -it openfire tail -f /var/log/openfire/info.log

Maintenance

Upgrading

To upgrade to newer releases:

Download the updated Docker image:

docker pull credija/openfire:{version}

Stop the currently running image:

docker stop openfire-credija

Remove the stopped container

docker rm -v openfire-credija

Start the updated image

docker run -name openfire-credija -d \
  [OPTIONS] \
  credija/openfire:{version}

Shell Access

For debugging and maintenance purposes you may want access the containers shell. If you are using Docker version 1.3.0 or higher you can access a running containers shell by starting bash using docker exec:

docker exec -it openfire-credija bash
