beta.kubernetes.io/arch label has been deprecated #723

Closed thedemoncat closed 3 years ago

thedemoncat commented 3 years ago

Can`t deploy openfaas in kubernates cluster: 0/1 nodes are available: 1 node(s) didn't match node selector.

Expected Behaviour

Openfaas is successfully deployed with arkade install openfaas --load-balancer

Current Behaviour

After starting openfaas, the pods do not start, because they do not find the required node label

Hi @TheDemonCat PRs are welcome, however we have not encountered such issues with Kubernetes on Raspberry Pi.

Alex

thedemoncat commented 3 years ago

This is not a Raspberry PI. These are the Yandex cloud provider servers. The problem is that you have an outdated API on the chart.

alexellis commented 3 years ago

What CPU architecture are they then? I have personally tested on armhf, arm64 and Intel with no scheduling issues?

PRs are welcome like I said.

thedemoncat commented 3 years ago

arm64. As for the PR, I understood. But unfortunately I will not do it in the near future. I have temporarily switched to other tasks for now. But I think I'll be back a little later

LucasRoesler commented 3 years ago

@alexellis @thedemoncat and @Waterdrips i think we can safely close this now that all of our images are multi-arch and we have removed the tolerations from the chart, see https://github.com/openfaas/faas-netes/pull/782

If you're happy then go ahead and /close
