Unable to install onto Kubernetes 1.18.3

[coder36]

I'm unable to install deis onto a fresh kubernetes cluster.

helm  install hephy/workflow --namespace deis --generate-name

Error: unable to build kubernetes objects from release manifest: [unable to recognize "": no matches for kind "DaemonSet" in version "extensions/v1beta1", unable to recognize "": no matches for kind "Deployment" in version "extensions/v1beta1"]

Versions:

kubectl --kubeconfig version

Any ideas ?

Thanks for the report! We are still supporting it, but for the time being if you want to use a supported version of Kubernetes (>= v1.16.x) then you need to enable some deprecated API versions

You can use a version earlier than 1.16 if that's an option for you, or you can... sec let me find the hint you give to kubelet when it starts with --runtime-config for K8s >v1.16.x and Workflow

--runtime-config=extensions/v1beta1/daemonsets=true,extensions/v1beta1/deployments=true,extensions/v1beta1/replicasets=true

This is not ideal, we have a lot of PRs to merge and test to make sure this is addressed, and the next version of Hephy Workflow v2.22 will resolve this permanently.

This has been fixed in the latest version of Hephy Workflow v2.22.1
