Merge Kubernetes Configs in Windows Machine¶
Ensure that kubectl is installed in Windows machine (Kubectl in Windows machine.md).
Next job is to fetch all configs from different clusters.
We can use scp to get that file in our workstation.
# Example
scp [email protected]:/home/hyperoot/k3s.yaml $HOME/.kube/k3s.yaml
Note: if you are using k3s, then the config will be placed at /etc/rancher/k3s/k3s.yaml. Make sure to move it to home directory and change ownership to current user instead of sudo chown hyperoot:hyperoot k3s.yaml
Once we have all the configs ready, we need to set KUBECONFIG to the PowerShell environment.
$env:KUBECONFIG = "$HOME/.kube/k3s.yaml;$HOME/.kube/another_config.yaml"
Now we can merge all these configs into one.
kubectl config view --merge --flatten > merged-config
A new file named merged-config will be created. Of course, we need to rename it to config as kubectl look for this by default. If you have an old config file, then take a backup before renaming the merged file.
Verify all the clusters using the following
kubectl config get-clusters
To switch clusters, refer to Change context in kubectl.md
