[ckan-dev] Solr Docker Hub Image

[Mila Frerichs]

Hello,

I’m getting more into CKAN lately and was setting up CKAN using the cool Dockerfile. 
But unfortunately the solr image (https://registry.hub.docker.com/u/ckan/solr/) is not working properly since it has an old schema.xml.

It’s a relatively easy fix since only the docker image has to be rebuild and uploaded to the hub. 
There are a few open and closed issue about this: 
https://github.com/ckan/ckan/issues/2157
https://github.com/ckan/ckan/issues/2255

It would be great if someone could update the image so that the instructions are working again.

Are you guys interested in adding a docker-compose file? I would have one ready to create a PR.

Thanks.
