Update Containerfile.acm and Containerfile.mce to use the official ART golang builder (registry.redhat.io/openshift/golang-builder:golang-builder-v1.26-rhel9) instead of the deprecated internal builder (registry.ci.openshift.org/stolostron/builder:go1.26-linux). This change ensures compliance with the ACM-45311 deadline of October 15, 2026, when the old internal builder will no longer be maintained.

Can you change -mod=mod to -mod=readonly to fix a CodeRabbit comment. This way I don't have to create a new PR. Thanks!

Same for here, change -mod=mod to -mod=readonly .

@Randy424 Looks great! I just requested some minor changes. Thanks! |
Per Feng's recommendation to fix CodeRabbit comment: use -mod=readonly instead of -mod=mod in both Containerfile.acm and Containerfile.mce. Signed-off-by: Randy Bruno Piverger <21374229+Randy424@users.noreply.github.com>

ACM-45311 requires all repositories consuming golang builders to migrate to the official ART builder (
registry.redhat.io/openshift/golang-builder) by October 15, 2026.registry.ci.openshift.org/stolostron/builder:go1.26-linux(deprecated, internal-only)registry.redhat.io/openshift/golang-builder:golang-builder-v1.26-rhel9(official ART, public registry)The floating tag
golang-builder-v1.26-rhel9automatically tracks the latest Go 1.26 builder for RHEL 9, ensuring security updates and maintenance.Impact on PR stolostron#6842
PR stolostron#6842 introduces the Go-based backend but currently uses the deprecated internal builder. This change brings it into compliance with ACM-45311.
Testing
Local build verification recommended:
Konflux pipeline should verify multi-arch builds (x86_64, ppc64le, s390x, arm64) with the new builder.
Deadline
October 15, 2026 — No extensions available per ART announcement.
