Reproduced with a unit test based on the Dockerfile and build config from https://github.com/openshift/builder/issues/129
Have fix in hand (one liner) ... just cleaning up / simplifying the unit test
Note to QE, we have a simplified reproducer: apiVersion: build.openshift.io/v1 kind: BuildConfig metadata: name: sample-build-docker-args-preset spec: source: dockerfile: |- FROM centos ARG foo=centos FROM $foo type: Dockerfile strategy: dockerStrategy: {} type: Docker which results in I0211 22:06:43.140914 1 builder.go:318] Starting Docker build from build config sample-build-docker-args-preset-17 ... F0211 22:06:43.209605 1 helpers.go:114] error: build error: error parsing name "$foo": error parsing image name "$foo": invalid reference format So at least the panic does not occur. Bug https://bugzilla.redhat.com/show_bug.cgi?id=1801875 has been opened against buildah so that we do not get F0211 22:06:43.209605 1 helpers.go:114] error: build error: error parsing name "$foo": error parsing image name "$foo": invalid reference format
Sorry one tweak to Ben's reproducer in #Comment 3 To get the panic, the dockerfile contents should just be ARG foo=centos FROM $foo The `FROM centos` was added to work around the panic in constructing a simple reproducer for https://bugzilla.redhat.com/show_bug.cgi?id=1801875
Thanks Gabe, I can reproduce the bug about Arg problem, and verified in 4.4.0-0.nightly-2020-02-13-192852 Steps: 1. Use bc to create build apiVersion: build.openshift.io/v1 kind: BuildConfig metadata: name: sample-build-docker-args-preset spec: source: dockerfile: |- ARG foo=ab FROM centos type: Dockerfile strategy: dockerStrategy: {} type: Docker 2. Using old cluster version,will have error http://pastebin.test.redhat.com/836101 3. Using the latest version, the error is fixed. [wewang@wangwen ~]$ oc get builds NAME TYPE FROM STATUS STARTED DURATION sample-build-docker-args-preset-1 Docker Dockerfile Complete 8 minutes ago 20s
FYI, About the following 2 scenarios still failed with "error: build error: error parsing name "$foo": error parsing image name "$foo": invalid reference format" in current latest cluster, will test them when https://bugzilla.redhat.com/show_bug.cgi?id=1801875 is fixed. Scenario 1: source: dockerfile: |- ARG foo=centos FROM $foo type: Dockerfile Scenario 2: dockerfile: |- FROM centos ARG foo=centos FROM $foo type: Dockerfile
Already had a bug to track about Comment 7: https://bugzilla.redhat.com/show_bug.cgi?id=1802202
