Docker Windows 的桌面无法启用 kube.netes 并出现错误 x509：未知授权机构签署的证书

Question

I am trying to enable kube.netes for Docker Desktop. Kube.netes 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 kube.netes.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://kube.netes.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 Kube.netes (still took a few minutes to start)

My solution:

1. delete $HOME/.kube/config
2. Restart Docker Desktop
3. notice the $HOME/.kube/config is back and your kubectl should work

I have multiple config* files in .kube directory - these stay intact
