Merge Kubernetes Configs in Windows Machine¶
Ensure that kubectl is installed in Windows machine (../Technology/kubectl in Windows machine).
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 ../Technology/Change context in kubectl
