Nit: Would be nice to have it configurable for downstream projects to adapt to their needs.

@HeavyWombat Shall I add it as another field for vulnerabilityScanOptions ? or Can I set it as an environment variable in some config or in the image-processing container ?

My initial feeling would be an environment variable.

Should be in config.go which reads from environment variables.

Again, thanks for the PR. I am generally speaking fine with it, but have a couple of detail questions.

In the message, should we say "check the BuildRun status, or see kubectl ..." ?
Can we put VulnerabilitiesFound
into a constant ? Would be nearby here:
BuildRunStatePodEvicted = "PodEvicted" |

I did that because it was easy to map it with the result from Trivy scan. I will create a different struct for trivy result.

I do not understand that check. Why do we need to check if the BuildRun exists ?

Because in my tests, I have already created the buildrun, otherwise I had to create a new function for running buildruns.
This condition is also present in validateBuildRunToSucceed
function.

Please add a comment, took me while to understand that img != nil
is the condition for a single image in a tar file.

This should be a number. The error returned by SetConfigFromEnv will cause the controller to panic and that's the desired behavior for invalid values.

Not really, just the vulnerabilities list. In case trivy command fails, it will print an error, but in that case exit code won't be 22.
