Nx reports success on Kaniko failure after credentials check

[tomaszkrzyzanowski]

While working on implementing nx-container on Bitbucket Pipelines with Kaniko engine (as it's only engine able to work in BB)

I discovered that when Kaniko will not find the right pair of credentials and fails the whole build, nx-container don't see any issue and reports success

Kaniko executor response while running manually from nx-kaniko image:

/workspace # executor --context /workspace --destination example/image:latest
error checking push permissions -- make sure you entered the correct tag name, and that you are authenticated correctly, and try again: checking push permission for "example/image:latest": POST https://index.docker.io/v2/example/image/blobs/uploads/: UNAUTHORIZED: authentication required; [map[Action:pull Class: Name:example/image Type:repository] map[Action:push Class: Name:example/image Type:repository]]
/workspace # echo $?
1
/workspace #

In CI last few lines of the successful build are:

to build the images, I have used command
npx nx affected --target=build-docker --base="origin/main" --head=HEAD --configuration=production --parallel=1
