healthcheck does not pass/return causing `docker compose up --wait` to wait forever

[tigerinus]

Use the docker-compose.yml suggested in README.md (or build a custom one - doesn't matter because it's an issue caused by container)

Then run docker compose up --wait in the path.

Expect: OpenHAB should be up and running in a healthy state

Actual: It waits forever...

Let's look at some other docker compose, like this one:

https://github.com/docker/awesome-compose/tree/master/wordpress-mysql

docker compose up --wait
[+] Running 2/2
 ⠿ Container wordpress-mysql-db-1         Healthy                                                   0.5s
 ⠿ Container wordpress-mysql-wordpress-1  Healthy                                                   0.5s

This is what's expected: The container should be in healthy state and --wait returns.

[wborn]

It'll stay in "starting" and becomes "healthy" after 5 minutes, see the HEALTHCHECK in the Dockerfile:

openhab-docker/debian/Dockerfile

Line 101 in 781ef91

HEALTHCHECK --interval=5m --timeout=5s --retries=3 CMD curl -f http://localhost:${OPENHAB_HTTP_PORT}/ || exit 1

That's because on slow SBCs startup can take several minutes and it would then endlessly restart the container during startup causing it never to become healthy.

You can reconfigure the healthcheck behavior in your compose file if you are using faster hardware, see:

https://docs.docker.com/compose/compose-file/#healthcheck
