Docker Desktop for Windows cannot enable kubernetes with error x509: certificate signed by unknown authority

Question

I am trying to enable kubernetes for Docker Desktop. Kubernetes is however failing to start.

My log file shows:

cannot get lease for master node: Get "https://kubernetes.docker.internal:6443/apis/coordination.k8s.io/v1/namespaces/kube-node-lease/leases/docker-desktop": x509: certificate signed by unknown authority: Get "https://kubernetes.docker.internal:6443/apis/coordination.k8s.io/v1/namespaces/kube-node-lease/leases/docker-desktop": x509: certificate signed by unknown authority

I have NO_PROXY env var set already, and my hosts file has 127.0.0.1 kubernetes.docker.internal at the end, as was suggested here

I appreciate any help

Answer 1

Below work around can help you resolve your issue.

You can solve this by

• Open ~.kube\config in a text editor
• Replace https://kubernetes.docker.internal:6443 to https://localhost:6443
• Try connecting again

From this issue

• Reset Docker to factory settings
• Quit Docker
• Set the KUBECONFIG environment variable to %USERPROFILE%.kube\config
• Restart Docker and enable Kubernetes (still took a few minutes to start)
