Support the same platforms with cert-manager

[anagno]

Hello and thank you for the nice project,

I would like to use the plugin in a raspberry pi kubernetes cluster, but the official images are only available for amd64. Is it possible to add builds for arm64 ? Probably it makes sense to support the same platforms as cert-manager.

I think the necessary changes for supporting the new builds are minimum. The only thing that has to change is the platforms in the build step

It should be changed to platforms: linux/amd64,linux/arm/v7,linux/arm64,linux/ppc64le,linux/s390x

Does it make sense to support more platforms?

Kind regards, Vasileios

I built it on a RPi4 in arm64 with docker buildx build --target=image --platform=linux/arm64 --output=type=docker,name=bwolf/cert-manager-webhook-gandi:0.2.0 --tag=cert-manager-webhook-gandi:0.2.0 --build-arg=GO_VERSION=1.17 . and issued a staging wildcard certificate with letsencrypt, so it looks definitely possible.

Supporting the request as it takes way too long to build on a RPi4 (~600sec)

Kubernetes: v1.22.7+k3s1 Cert-manager: v1.7.1

It builds correctly on arm64 architecture. Just need to remove the hardcoded amd64 achitecture in the Makefile

sed 's/amd64/${ARCH}/' Makefile -i
