Ignore certain exit codes in GitLab CI pipeline script

Question

I have a script in GitLab CI but one command sometimes ends with exit code 101 what is OK in my use case and I want to ignore it.

I would use true:

failing_script || true

But it will ignore all exit codes, so I will not be notified when there will be some other error.

I would need something like this:

failing_script || (true only if exit code 101)

Answer 1

This seems to be what you're looking for:

failing_script|| [ $? -eq 101 ]
