fix(operators): cross-compile the operator image for the target arch#30
Merged
Conversation
The Dockerfile declared ARG TARGETARCH=amd64 with a default value, which shadows the per-platform value buildx auto-populates during a multi-arch build. So the release's linux/arm64 image got an amd64 manager binary: the manifest claimed arm64, but the bytes were amd64, and the operator CrashLooped on Graviton nodes with "exec /manager: exec format error". Declare TARGETOS/TARGETARCH without defaults (the canonical buildx pattern) so buildx populates them per-platform and Go cross-compiles correctly. Plain docker build without --platform leaves them empty and builds natively; an explicit --build-arg still forces a specific arch. Bumps the chart to 0.1.1 for the corrected release.
