CKAN is a powerful Data Management system used to power Open Data catalogues across the world, including many national portals. It has many publishing and curating features and offers a full API to access both the metadata and certain data formats.
Full documentation for CKAN can be found at http://docs.ckan.org.
This option requires Docker Compose to be installed.
Docker Compose will take care of running and linking the following services:
To run a CKAN instance with the FIWARE Labs extensions enabled, clone this repository and run:
er-compose up -d
After a few minutes you will be able to access the CKAN site at http://localhost:8000
NOTE: the oauth2
authorization extension is not enabled by default as it
requires further configuration. Edit the relevant settings on setup/production.ini
.
You may need to set the OAUTHLIB_INSECURE_TRANSPORT
env var if not serving CKAN under https,
check the documentation for details.
CKAN configuration can be modified via the setup/production.ini
file, which is
mounted as a volume on the CKAN image. Check the documentation for all the
available configuration options.
Additional extensions can be easily installed editing the main Dockerfile
.
If you require changes to the Solr schema, these can be made to
the solr/ckan/conf/schema.xml
file, which is also mounted as a volume on
the Solr image.
If you want to set up the Postgres and Solr servers separately you can run the image directly with the following command:
er run -p 8000:8000 -e CKAN_SQLALCHEMY_URL=postgresql://ckan_default:pass@localhost/ckan_default -e CKAN_SOLR_URL=http://localhost:8983 -e CKAN_SITE_URL=http://localhost:8000 fiware/ckan
You might want to use a .env
file to define all your environment variables and pass that
as a parameter:
er run -p 8000:8000 --env-file=.env fiware/ckan
If you look at the log outputted when running docker-compose up
you might see errors like
these:
gres_1 | WARNING: there is already a transaction in progress
_1 | IntegrityError: (IntegrityError) duplicate key value violates unique constraint "user_name_key"
These are caused by the different services starting at the same time and can be safely ignored as the CKAN application will wait until the Postgres service is ready to start.
Other messages that you might see are along these lines:
ING: Service "ckan" is using volume "/srv/app/production.ini" from the previous container.
This is an issue with Docker Compose which should be fixed on version 1.5.2.
Datapusher won't work when running under Docker Compose because currently there is no support for biridectional container linking. This will be addressed on future Compose versions as part of changes in Networking support (see this issue for details).
