I read this post about how to share kube config.
It says that kubectl config view --flatten --minify is the way to get kube config file.
But when it comes to use this config file, I am confused.
For example, if the output is saved as config-yuta, do I always specify the config file like this? kubectl --kubeconfig=config-yuta cluster-info
I feel too troublesome to specify --kubeconfig=xxx always. I just want to switch the context and do like kubectl cluster-info without specifying a certain file when I have multiple clusters.
Should I merge ~/.kube/config with the output?
If so, how can I do it correctly?
You can set multiple clusters in the same kubeconfig file, see this doc
Another solution to use multiple kubeconfig files is to set the environment variable KUBECONFIG
export KUBECONFIG=<path to config-yuta>And finally it's also possible to merge the file config-yuta with the default kubeconfig with this command:
KUBECONFIG=~/.kube/config:<path to config-yuta> kubectl config view --flatten > ~/.kube/config
