Build pod fails during build phase

[pranavek]

I have a ClusterStack that refers to Paketo Jammy Base Stack. Intermittently, the build init container is terminated with exit code 51. I can't figure out the root cause as the build container logs doesn't have any error logs, it just says signal: killed. How can I debug the issue? Any help in this regard is highly appreciated.

Logs from the build container - The build ran only for 12 milliseconds

Describe pod output - Terminated with Error 51

Kpack: 0.1.2.3
Paketo Jammy Build pod: docker.io/paketobuildpacks/build-jammy-base:0.1.86

The CNB spec says that /cnb/lifecycle/builder exits with code 51 if there's a Buildpack build error. What buildpacks are you using (i.e. what does the DETECT phase print out)?

The fact that it's intermittent makes me suspect that there's some network issues that's causing a buildpack to error out. It would be nice if we had a way to turn on debug logs but unfortunately that's not supported right now.
