Docker

We offer the Docker image zotonic/zotonic-dev which contains build tools and Erlang.

It can be used for development work on Zotonic itself, where you’ll mount your Zotonic directory as a volume in the container.

To use this image, first download and install Docker.

zotonic-dev

You can use the zotonic/zotonic-dev image for doing development work on Zotonic and Zotonic sites.

Start the container from your local Zotonic clone:

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

Start the container:

$ cd zotonic
$ ./start-docker.sh

This uses Docker Compose to start the Zotonic container and a PostgreSQL container.

On first start Zotonic will be compiled and all dependencies are fetched. This can take quite some time if you are not running on Linux (Docker’s file i/o is quite inefficient on non-Linux platforms).

A shell prompt will appear after the build is complete. Now Zotonic can be started:

bash-4.4$ bin/zotonic debug

You can stop Zotonic (Erlang) by typing Ctrl+C twice.

The configuration, including the Zotonic status site password, can be found with:

bash-4.4$ bin/zotonic config

Zotonic’s port 8443 and 8000 are exposed as local ports. You can view the Zotonic status page at https://localhost:8443/. You can log in using the username wwwadmin and the password from the config.

Zotonic is running with a self-signed certificate. The certificate can be found in docker-data/etc-zotonic/security/self-signed/.

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.

You can stop the container using Ctrl+D at the Bash shell prompt.
