Allow Educates to run on GKE on arm64 nodes properly

[jorgemoralespou]

Is your feature request related to a problem? Please describe.

It seems as GKE adds a taint to GKE nodes to prevent arm64 workloads to be placed in them (https://cloud.google.com/kubernetes-engine/docs/how-to/prepare-arm-workloads-for-deployment).

Describe the solution you'd like

Investigate a way to either:

• Remove the taint
• Add tolerations to Educates workloads (via CLI and terraform install)

Describe alternatives you've considered

No response

Additional information

It seems that adding this snippet to Educates workloads known to run on arm64 will solve the problem:

  affinity:
    nodeAffinity:
      requiredDuringSchedulingIgnoredDuringExecution:
        nodeSelectorTerms:
        - matchExpressions:
          - key: kubernetes.io/arch
            operator: In
            values:
            - arm64
            - amd64

But still we would need to solve the problem of making Educates workshops work as well.

Another option is to use a kyverno policy
