Batch run commands against clusters

[richardcase]

Do you think it would be a good idea to enable batch running of kubectl commands against a list of clusters?

Something like this:

kconnect run --alias cluster1,cluster2 --commands-file commands.txt --output json

And the file could contain:

kubectl get pods -A

@ramnar @rajarajanpsj @seankelly001 - what do you think?

[seankelly001]

Think this is a great idea, would make kconnect very powerful!

1 option could be to use a yaml file and run it like so:
kconnect run -f run.yaml --password mypassword123

apiVersion: kconnect.fidelity.github.com/v1alpha1
kind: RunConfig
metadata:
name: run
spec:
alias:
- cluster-1
- cluster-2
commands:
- kubectl exec mypod -- somecommand
- kubectl logs mypod

I like the idea of using a declarative config for this. Thats a lot better.

[ramnar]

Both are really nice approaches to solve the problem.First one is easy to use for single command and second one for multiple commands. I will be happy to contribute to this feature, whichever approach we finalize on.

[ramnar]

I was thinking about it. As yaml is a one time configuration, second approach looks great

[richardcase]

Lets go with the yaml approach then. That would be great if you wanted to contribute this @ramnar . Let me know if you need any help getting started.
