Docker health check

[janreinhardt]

Could we please have a docker health check for the Arcane container itself?
Also, could Arcane please display the health state instead of just running/created for its managed containers?
Would be great!

Ok I just discovered the health status of running containers somewhat hidden in the ‚Status‘ column. I think it would be better if it was a label in the ‚State‘ column.

The internal API has a healthcheck endpoint at /api/health

To implement this as a healthcheck in docker compose:

    healthcheck:
      test: curl localhost:3552/api/health | grep \"status\":\"UP\"
      interval: 10s
      timeout: 5s
      retries: 3
      start_period: 15s

Working fine for me in 2.0.2

You're right. The curl command works via command line. I made the error of executing docker exec arcane which curl and saw this error late the other night, but I didn't read the error carefully.

OCI runtime exec failed: exec failed: unable to start container process: exec: "which": executable file not found in $PATH: unknown

As a result, I assumed that curl may have been excluded from v2. Regardless, my healthcheck fails for both Arcane and Arcane Agent. That's the reason that prompted me to execute which.

Do your containers show up healthy in the GUI? Mine used to before upgrading to v2.

You're right - arcane 2.x is missing grep. Not sure how to work around that, I think it would need to be reintroduced. Theres also no sed, awk, etc. Theres also no shell software so we cant use bash matching either.

@kmendell thoughts?

I knew I wasn't crazy. LOL. I thought I remembered the image including bash or sh. I already deleted my backup and didn't want to risk causing damage to v1 in case their with things that got migrated. I could open a new issue to report this.

I just reported the issue: #2927.
