When running linkerd upgrade --from-manifests the following error occurs:
linkerd upgrade --from-manifests install.yaml > install-new.yaml
× Failed to parse Kubernetes objects from manifest install.yaml: no kind "APIService" is registered for version "apiregistration.k8s.io/v1" in scheme "pkg/runtime/scheme.go:101"This is a known issue with a workaround.
The workaround is to export the secret/linkerd-identity-issuer and configmap/linkerd-config resources to a separate manifest file, then use the generated file as an argument to linkerd upgrade --from-manifests:
kubectl -n linkerd get \
secret/linkerd-identity-issuer \
configmap/linkerd-config \
-oyaml > linkerd-manifests.yaml
then:
linkerd upgrade --from-manifests linkerd-manifests.yaml
