docker 26 compatibility

When setting up with the latest docker 5:26.0.2-1~ubuntu.22.04~jammy the datapusher container fails and ckan is stuck on "starting"

Workaround: downgrade to 5:25.0.5-1~ubuntu.22.04~jammy

Note that (the old, unmaintained) https://github.com/okfn/docker-ckan/ doesn't suffer from this issue.

@kowh-ai looks like #136 resolves this issue. Maybe we should consider it for both the docker-compose files?

Somebody here ckan/ckan#8170 (comment) had similar issue in Docker 26.0.0 and did a quick fix by replacing health check condition by wget command from localhost to 0.0.0.0.

I able to replicate the problem and confirmed that the quick fix did work on Docker version 26.1.0 on top on focal and jammy ubuntu.
