Add Expected Log validation about container-structure-test HOT 3 OPEN

I've faced the same issue, and I agree that it would be nice to have built-in support for this use case in container-structure-test.

As a workaround, if available in the image, I've used the Linux timeout command to set a maximum duration for the command under test. It's a bit of a hack, but it works.

Something like that should do the trick:

command: "timeout"
args:
  - --preserve-status
  - 3s
  - docker-entrypoint.sh postgres

from container-structure-test.

Logging is typically done through stderr. The expectedError field in the command test should allow you to perform a regex match over the stderr output.

Command tests have to run to completion in order to capture its state of the test container that is created from the image. You will need to invoke your process (psql, it looks like?) in a way that runs to completion. Perhaps you can run the server process as a daemon/background process, get the PID then immediately send a kill -INT signal as part of your test?

Thanks! The log can be redirected somehow through the stderr.
However, I don't think I can run the server process in background through this tool. I was wondering if it could be possible leveraging the setup field but I see that the function delegates the process invocation to the ProcessCommand, which waits for the command to exit.
