Multiarch Images that include arm64

[DWSR]

CRDB supports arm64 (among other archs) so the operator should as well. This is relevant to anyone running e.g. Graviton (AWS), Tau (GCP) or Ampere (OCI) instances.

I have also just run into this issue. arm64 is becoming very common.

Support for ARM64 is critical for our workloads as the CPU architecture represents a 40% cost per transaction savings. Is there any contribution I can assist with to progress this effort?

I don't know bazel enough to make a PR but if you want to get an arm64 build out of the repo you can do:

GOOS=linux GOARCH=arm64 go build -o cockroach-operator -v cmd/cockroach-operator/*.go

At any particular commit.

That gave me:

cockroach-operator: ELF 64-bit LSB executable, ARM aarch64, version 1 (SYSV), statically linked, Go BuildID=NiSUAYgI0rbcdPA7PYjc/UFkJjm-xuVoYR4fPsmMj/uMfJt6MBxBsHXmbnuZ9r/oydO3GqKyb2LA7yOqW9U, with debug_info, not stripped

Then you can copy the binary into a docker container.

Obviously not official nor supported but I set up a mutli-arch build pipeline for cockroach-operator using those principles: https://github.com/jrcichra/cockroach-operator-multiarch

It's working on my oracle cloud k8s cluster.
