ArangoDeployment spec.architecture silently ignores additional architectures

[ddelange]

Hi :wave:

it would be cool if specifying multiple architectures in an ArangoDeployment spec.architecture would result in multiple nodeAffinity entries on the pod specs:

in the original implementation there was an error "Only one architecture type is supported currently", but that seems to have disappeared before/during/after merging that PR.

only the first architecture specified here is respected, however. the rest is ignored (only one nodeAffinity is added to the pods). maybe the error should not have gone 🤔 ref https://github.com/arangodb/arangodb-docker/issues/110#issuecomment-1273629942
