Automagic support for arm64 deployments

[sdlarsen]

The image for the default-backend defaults to k8s.gcr.io/defaultbackend-amd64 in the helm chart, which naturally fails when deploying on arm64. It would be nice to have it point to a manifest with all supported architectures (at least amd64/arm64)

Thanks I'll have a look on the options out there. In the mean time you can try simply not to enable the default backend, haproxy ingress will make haproxy to expose a simple 404 page itself if the default backend isn't configured. Other than that since v0.14 you can also create your own 404 page, maybe you want to give this a try.

Thanks @jcmoraisjr, disabling the default-backend didn't work out for me at first glance anyway (something with not getting any certs from cert-manager). I'll just keep it on x86_64 for now...
