Solr images for rapid CKAN development and testing

ckan-solr

Pre-configured Solr Docker images for CKAN.

Note: These images are not vulnerable to CVE-2021-44228 / Log4J2 as are built on top of patched upstream Solr images.

You can get a local Solr instance targeting a specific CKAN version by running the following command:

docker run --name ckan-solr -p 8983:8983 -d ckan/ckan-solr:2.9

The following versions are available as different image tags:

CKAN Version	Solr version	Docker tag	Legacy Docker tags	Notes
2.7	Solr 6	ckan/ckan-solr:2.7	ckan/ckan-solr-dev:2.7
2.8	Solr 6	ckan/ckan-solr:2.8	ckan/ckan-solr-dev:2.8
2.9	Solr 6	ckan/ckan-solr:2.9	ckan/ckan-solr-dev:2.9
2.9	Solr 8	ckan/ckan-solr:2.9-solr8		Requires at least CKAN 2.9.5
2.10	Solr 8	ckan/ckan-solr:2.10
master	Solr 8	ckan/ckan-solr:master		The master image is not automatically updated and might be out of date

All these images expose the CKAN Solr endpoint at http://localhost:8983/solr/ckan, so that's what you should set the value of solr_url in your ini file to.

Additionally, there is a multi image which contains cores for all CKAN Versions in the same Solr server:

docker run --name ckan-solr -p 8983:8983 -d ckan/ckan-solr:multi-solr6

This will expose the following Solr endpoints (based on Solr 6):

• http://localhost:8983/solr/ckan-2.6
• http://localhost:8983/solr/ckan-2.7
• http://localhost:8983/solr/ckan-2.8
• http://localhost:8983/solr/ckan-2.9

There is no multi image for Solr 8 yet.

Building the images

For Solr 6 based images (ie CKAN 2.6 to 2.9), go to the solr-6 directory and use the Makefile included:

# Default version in 2.9
make build
make build CKAN_VERSION=2.8
make build-multi

For the Solr 8 based image (ie CKAN 2.10), go to the solr-6 directory and use the Makefile included:

# Default version in 2.10
make build
make build CKAN_VERSION=2.9

Note that pre-CKAN 2.10 images use tags with a -solr8 suffix, ie ckan/ckan-solr:2.9-solr8

Use your own configuration files

If you want to play around with the solr config files you can copy them from the container to your local host and then run the container with a bind mount.

1. Run a container (eg multi):

   docker run --name ckan-solr -p 8983:8983 -d ckan/ckan-solr:multi
   

2. Copy the config file of the target core to your machine (eg ckan-2.9):

   docker cp ckan-solr:/opt/solr/server/solr/ckan-2.9/conf ./my_conf
   

3. Stop the container:

   docker stop ckan-solr
   

4. Run the container with a bind mount:

   docker run -p 8983:8983 --mount type=bind,source="$(pwd)"/my_conf,target=/opt/solr/server/solr/ckan-2.9/conf -d ckan/ckan-solr:multi
   

5. Edit your local files

6. Reload the core using the Solr admin page: http://localhost:8983/solr/#/~cores/
