Bitbucket Pipeline execution showing success when is not supposed to do so

[dpalmisano]

Dear all,

I'm struggling a bit with an issue with Bitbucket Pipeline.

I have a pipeline that runs a Python script. This script basically starts a web server (using subprocess) and calls few HTTP endpoints exposed by this web app. In order to work properly, we need my_init running in our Docker container.

We artificially made the script to return a non-zero exit code but Bitbucket Pipeline still terminates the execution as a successful one.

We noticed that this behaviour happens only when my_init is running in our pipeline Docker container.

It seems that somehow, my_init prevents Bitbucket Pipeline to grab the correct exit code of the script.

This behaviour happens regardless my_init is started: we tried to start it as a step of the Pipeline, or within the Python script.

We tried to run an alternative python script that mimics the actual one, with the difference that my_init is not involved and the Pipeline execution definitely matches the return code of the script: failure when the script raises an exception, success when the script returns a zero code.

Any help will be really appreciated!

Thanks
