Failing to build images in OpenShift 4

[mgencur]

Running the ci-operator against OpenShift 4 fails to build some images. The root, src and bin images are built correctly but the following image that is based on base and uses inputs from bin fails. It can't find the Dockerfile that the image is based on.
When using this ci-operator config. The build fails for all images with a similar error: error: open /tmp/build/inputs/openshift/ci-operator/knative-images/autoscaler/Dockerfile: no such file or directory
The Pod that is created for this image build creates init-container named "manage-dockerfile" and that one fails.
Note: Using the same version of ci-operator, and OKD 3.11, everything works fine.

error: open /tmp/build/inputs/openshift/ci-operator/knative-images/autoscaler/Dockerfile: no such file or directory

[petr-muller]

Interesting. I just run ci-operator --git-ref openshift/knative-serving@release-0.2 --config ci-operator/config/openshift/knative-serving/openshift-knative-serving-release-0.2__v4.0.yaml --target=[images] with the current ci-operator and fresh openshift/release master branch successfully.

Do you have a link to failing ci-operator run?

[mgencur]

I have my own OpenShift 4 cluster and KUBECONFIG pointing to it. Did you really run it against OpenShift 4? The OpenShift at https://api.ci.openshift.org is 3.11 and there it runs fine.

[petr-muller]

Oh, I misunderstood the report.

I believe nobody currently really runs ci-operator workloads on 4.0 cluster right now, and while we'll need to eventually investigate and fix this, I'm afraid it's not urgent enough for priority fix, sorry.
