What happened?
After I restart the OS I get the error below when running any kubectl command.
Unable to connect to the server: tls: failed to verify certificate: x509: certificate is valid for 127.0.0.1, ::1, 127.0.1.1, 10.96.0.1, not 192.168.2.10
To fix it I had to run
sudo k0s stop
sudo k0s install controller --single --force
sudo k0s start
again then kubectl works again.
This is my /etc/k0s/k0s.config file.
apiVersion: k0s.k0sproject.io/v1beta1
kind: ClusterConfig
metadata:
name: k0s
spec:
api:
address: 192.168.2.10
k0sApiPort: 9443
port: 6443
sans:
- 192.168.2.10
telemetry:
enabled: false
After the system I rebooted and kubectl throws tls error and I ran sudo k0s kubeconfig admin I saw that the sever cluster address is 127.0.0.1 instead of 192.168.2.10. Also, I don’t know where the 10.96.0.1 IP in the error message comes from.
Steps to reproduce
- Install k0s using confit above
- Generate kubeconfig file
- Reboot system
Expected behavior
K0s should retain the api.address from the installation config.
Actual behavior
K0s reverted the api address to 127.0.0.1 after system reboot instead of retaining the custom 192.168.2.10 api address.
