AWS 'eb deploy' always returns returncode 0

Question

I'm using 'eb deploy' in my continuous integration script. I'm having 2 problems with it:

• It always returns returncode 0, even if there is an error. This breaks my deploy pipeline, because there is no way to detect an error.

• It displays output only after command is finished.

Is there any way to make 'eb deploy' to work as any normal script and return proper error codes?

This is a know issue reported upstream here. You can fix it by using grep in a pretty straight forward way. Instead of:

eb deploy 

Use grep to get the success string. This will return a non-zero status (ie: failure) if it can't be found:

eb deploy | tee /dev/tty | grep "update completed successfully"

Note how I used tee to make sure that the output can still be seen on the continuous integration portal (in my case circleci).
