Is the CKAN container healthy and remains in that state for at least 5 minutes? The nginx container will not start until CKAN is deemed "healthy"

The Nginx container fails to start because the CKAN container never reports as healthy, which is due to the health check failure of the CKAN container.

The health check (wget http://localhost) fails because the IPv6 loopback address (::1) appears to be non-functional within the container. However, the IPv4 loopback address (127.0.0.1) operates correctly. This issue also affects the Datapusher container.

docker compose exec -it ckan wget -O /dev/null http://localhost:5000
Connecting to localhost:5000 ([::1]:5000)
wget: can't connect to remote host: Connection refused

docker compose exec -it ckan wget -O /dev/null http://127.0.0.1:5000
Connecting to 127.0.0.1:5000 (127.0.0.1:5000)
saving to '/dev/null'
null                 100% |*************************************************************************************************************************| 11617  0:00:00 ETA

This issue is related to this change in Docker: https://github.com/moby/moby/pull/47062, and it seems to primarily affect those running Docker version 26.

$ docker version
Client: Docker Engine - Community
 Version:           26.1.1

To work around this problem, you can disable IPv6 in the containers in the docker-compose.yml file:

ckan:
  [...]
  sysctls:
    - net.ipv6.conf.all.disable_ipv6=1
  [...]

datapusher:
  [...]
  sysctls:
    - net.ipv6.conf.all.disable_ipv6=1
  [...]
