[BUG] Docker Healthcheck broken since newest update

[saschabrockel]

Describe the bug
I'm running this health command curl --fail http://localhost:8080/api/health || exit 1 for the health check of the container. Since the newest update, it's not working anymore. I can do the exact same command in the container itself without problems.

I'm on master#5977f7c.

The container health logs say the following
OCI runtime exec failed: exec failed: unable to start container process: exec: "/bin/sh": stat /bin/sh: no such file or directory: unknown

Sorry but what is the fix? I cannot see it.

I'm using it like this:
--health-cmd="curl --fail http://localhost:8080/api/health || exit 1" --health-interval=1m --health-timeout=10s --health-retries=3

It is done as recommended. I don't think it has anything to do with this.

apologies, I referenced the wrong Issue. Here's the correct one - #601

Basically if you're using Docker-compose, you need to specify the shell array syntax.

I'm actually not sure if theres a way to do that when using the docker cli...

Let me re-open this issue.

looks like a known issue without any fix:

• Image from "scratch" has no shell, but passing the --health-cmd to docker run uses CMD-SHELL moby/moby#43843
• Image from "scratch" has no shell, but passing the --health-cmd to docker run uses CMD-SHELL docker/cli#3719

I considered baking the healthcheck into the docker build, however that will cause issues for users that change their default port.

Might still be worth it

Did that baking in already happen? I am unable to use Scrutiny now as I have put it on a different port. Changing the port back to 8080 seems to work, otherwise the web container says it's unhealthy. But is not really a good solution as it is a very common port which I do not want to dedicate to Scrutiny. I don't think that breaking the possibility to change ports is the way forward.

Okay no, my issue seems unrelated. But I still think creating issues for users who change the default port is not a good balanced decision compared to the advantages.
