Hello,
Linkerd says the cluster version is too old, is there a quick fix with kind:
$ linkerd check --pre Linkerd core checks =================== kubernetes-api -------------- √ can initialize the client √ can query the Kubernetes API kubernetes-version ------------------ × is running the minimum Kubernetes API version Kubernetes is on version [1.18.2], but version [1.21.0] or more recent is required see https://linkerd.io/2.12/checks/#k8s-version for hints √ is running the minimum kubectl version pre-kubernetes-setup -------------------- √ control plane namespace does not already exist √ can create non-namespaced resources √ can create ServiceAccounts √ can create Services √ can create Deployments √ can create CronJobs √ can create ConfigMaps √ can create Secrets √ can read Secrets √ can read extension-apiserver-authentication configmap √ no clock skew detected linkerd-version --------------- √ can determine the latest version √ cli is up-to-date Status check results are ×
Kind version is 0.8.1:
$ kind version kind v0.8.1 go1.14.2 linux/amd64

After the pre-checks, the step
linkerd install --crds | kubectl apply -f -
is needed:linkerd install --crds | kubectl apply -f - linkerd install | kubectl apply -f - linkerd check linkerd viz install | kubectl apply -f - kubectl -n linkerd-viz get pods linkerd viz check linkerd dashboard

The
tap
command has changed too:Command "tap" is deprecated, use instead 'linkerd viz tap [flags] (RESOURCE)'
