nickstenning/ckan repository overview

This image contains a vanilla configuration of CKAN. You can use this image as-is if you specify the location of a Postgres database and a Solr core on startup:

docker run -i -t -p 80 \
  -e DATABASE_URL=postgres://user:pass@hostname/db \
  -e SOLR_URL=http://hostname:8983/solr/ckan_default \
  nickstenning/ckan:2.2

This will run CKAN, connect to the database, and initialise it if need be. Configuring Solr will have to be done separately⁠. There are a couple of other environment variables you can use to customise the deployment, including GUNICORN_NUM_WORKERS and ERROR_EMAIL, which do what you might expect.

Alternatively, and perhaps more realistically you can use this image as a base for extension. If a configuration file is injected to /etc/ckan/default.ini, the image will use that and ignore the DATABASE_URL, SOLR_URL, and ERROR_EMAIL environment variables. (GUNICORN_NUM_WORKERS is still used.)

A minimal Dockerfile that use this image as a base might look something like this:

FROM nickstenning/ckan:2.2
ADD ./mycustomconfig.ini /etc/ckan/default.ini

Lastly, the CKAN file store is at /var/lib/ckan, and in a production environment you would almost certainly mount this data volume outside the running container:

docker run ... -v /mnt/storage:/var/lib/ckan ...
