docker-compose up does not work

[dmfenton]

The way that you are specifying environmental variables in these lines is incorrect: https://github.com/ckan/ckan/blob/master/contrib/docker/my_init.d/50_configure#L36-L49

As a result the CKAN container cannot connect to the DB or SOLR

ckan | *** Running /etc/my_init.d/50_configure...
ckan | /etc/my_init.d/50_configure: 37: /etc/my_init.d/50_configure: DB_ENV_POSTGRES_USER: parameter not set
ckan | no DATABASE_URL specified and linked container called 'db' was not found
ckan | *** /etc/my_init.d/50_configure failed with status 1
ckan |
ckan | *** Killing all processes...
ckan exited with code 1

I added the ENV's for DATABASE_URL and SOLR_URL directly into docker-compose.yml and everything works.

version: '2'
services:
  ckan:
    container_name: ckan
    image: ckan/ckan:latest
    depends_on:
      - db
      - solr
    links:
       - db
       - solr
    ports:
       - "80:80"
    environment:
       DATABASE_URL: "postgresql://ckan:ckan@db:5432/ckan"
       SOLR_URL: "http://solr:8983/solr/ckan"
  db:
    container_name: db
    image: ckan/postgresql:latest
  solr:
    container_name: solr
    image: ckan/solr:latest

It's a know issue, im working improving the docker image of ckan, you can use the docker-cloud.yml in http://cloud.docker.com for now, or follow this legacy instructions http://docs.ckan.org/en/ckan-1.3.3/maintaining/installing/install-using-docker.html#installing-ckan

The actual image is not ready for production, CMD script and CKAN docker image needs to be full rewrite

[dmfenton]

Why not update the docker compose file until that work is done?

[deinok]

Because it docker-compose.yml should work without that ENV, they are in the postgres image, the link between the containers works well, but https://github.com/ckan/ckan/blob/master/contrib/docker/my_init.d/50_configure should handle that, but is going to be rewrited. I will rewrite it less than a week, on this sunday will be PR with the stability improvements and size reduced.

[dmfenton]

Any update on this?

[deinok]

I'm looking the documentation, for some reason, when using docker run -d -p 80:80 --link db:db --link solr:solr ckan/ckan but docker-compose dont detect the ENV of the links.
Also we are moving the base image to https://hub.docker.com/_/httpd/
I'm having problems to serve CKAN and its WSGI

[dmfenton]

That's because envs and links are deprecated. I'd recommend using the docker network feature instead. Then the containers can communicate via service name quite easily. I'm working on an implementation and will share when I finish.

If you do want to use the link feature, instead of looking for an env, you can still just use the container name as a URL e.g. solr or postgres

[rwillmer]

Any news on this?

[dmfenton]

@rwillmer I have a working implementation here: https://github.com/dmfenton/ckan-docker

[rwillmer]

thanks @dmfenton

[deinok]

@dmfenton Should be fixed, can you check it?

[3vivekb]

We have a pretty far along build https://github.com/vta/Open-Data-Portal

We decided to close old issues that are not actively worked on so that we can focus our effort and attention on issues affecting the current versions of CKAN.

If this issue is still affecting the version of CKAN you're working with now, please feel free to comment or reopen the issue.

If you do reopen this issue, please update it with new details. One reason it might not have been resolved in the past is that it wasn't clear how a contributor could address the issue.
