Kubectl Action

I archived this repository because I think there are now more appropriate options like helm and argocd

This action allows you to deploy to a kubernetes cluster.

Alternatives:

• steebchen/kubectl

Inputs

kubeconfig

Base64 encoded .kube/config file, to generate use:

cat .kube/config | base64

Outputs

output

kubectl commands output
