No repository files or tests are named; start by reproducing the Source to Image submission on Kubernetes 1.20.10 with Kubesphere 3.1.1 and inspect the s2ibuilder webhook and pod events. Done means publishing the app without a Dockerfile completes without the webhook connection refusal or ImagePullBackOff errors.
