Docker

We offer three Docker images:

  • zotonic/zotonic-full contains both Zotonic and PostgreSQL. Use this to get started quickly if you want to build sites on Zotonic.
  • zotonic/zotonic contains only Zotonic. This image is most useful in production setups or when you’re using Docker Compose with a separate database container.
  • zotonic/zotonic-dev contains build tools and Erlang. Use this image for development work on Zotonic itself, where you’ll mount your Zotonic directory as a volume in the container.

To use any of the images, first download and install Docker.

Start a Zotonic image on your Docker machine:

# use a stable version:
$ docker run -d -p 8000:8000 zotonic/zotonic-full:0.17.0

# or a branch:
$ docker run -d -p 8000:8000 zotonic/zotonic-full:0.x

# or run the latest version from master:
$ docker run -d -p 8000:8000 zotonic/zotonic-full:latest

Mount a volume that contains your Zotonic sites:

$ docker run -d -v `pwd`/sites:/opt/zotonic/user/sites zotonic/zotonic-full

And mount a volume with your custom Zotonic modules:

$ docker run -d -v `pwd`/sites:/opt/zotonic/user/sites -v `pwd`/modules:/opt/zotonic/user/modules zotonic/zotonic-full

zotonic-dev

You can use the zotonic/zotonic-dev image when you’re doing development work on Zotonic. Start the container from your local Zotonic clone:

$ git clone https://github.com/zotonic/zotonic.git

To start the container, use Docker Compose:

$ docker-compose run --service-ports zotonic sh

This opens a shell prompt in the Zotonic container. A PostgreSQL container will be started automatically as well. In the Zotonic container, you can enter any command. So, to start Zotonic in debug mode:

$ bin/zotonic debug

The --service-ports flags exposes Zotonic’s port 8000 as your local port 80, so you can view the Zotonic status page at http://localhost.

You can also run other commands in the container, such as running the tests:

$ bin/zotonic runtests

Any changes you make in the Zotonic source files will be propagated to the container and automatically compiled.
