The db_server Dockerfile is a thin repack of the multi-arch mysql:8.4 base (two COPYs and a chmod), but the kaniko step only builds the Cloud Build host platform, so every published gcr.io tag is amd64-only. That leaves arm64 consumers of the sigstore/helm-charts trillian chart unable to run the log storage at all. Switch just this image to a buildx multi-platform build using Cloud Build's documented recipe: install binfmt handlers, create a docker-container builder, and build/push both platforms in one step. The QEMU emulation only covers the chmod layer; the Go images are untouched. The kaniko registry cache flags are dropped for this step since the build is two COPY layers on a pulled base.

We deploy trillian on arm64 Kubernetes nodes through the sigstore/helm-charts trillian chart, which pins
gcr.io/trillian-opensource-ci/db_server. Every published tag of that image (checked through v1.8.0) is a single-manifest amd64 image, so the MySQL pod cannot run on arm64 hosts and the whole log stack is held to amd64. Downstream we worked around it by overriding the chart's image (chainguard-dev/mono#62571), but the image itself is the right place to fix this.The Dockerfile is already multi-arch-ready: it is a thin repack of the multi-arch
mysql:8.4base, two COPYs and a chmod. The amd64-only output comes from the build, since kaniko builds only the Cloud Build host platform. This switches just the db_server step to Cloud Build's documented multi-platform recipe: install binfmt handlers, create adocker-containerbuildx builder, and build/pushlinux/amd64,linux/arm64in one step. QEMU emulation only covers the chmod layer; the Go-binary images are untouched. The kaniko registry cache flags are dropped for this one step, since the build is two COPY layers on a pulled base.
