Resource Configuration
We can easily get the configs declared declaratively in yaml format.
If you create it imperatively & do not document it then it would be hard to redeploy if something goes wrong.
Hence we query the
kube-apiserver
and save all resources configs for all objects created on serverkubectl get all -A -o yaml > back.yaml
We use tools like velero (ARK) that covers every resources excluded by above commands
