Secrets

KUBE_CONFIG_DATA – required: A base64-encoded kubeconfig file with credentials for Kubernetes to access the cluster. You can get it by running the following command:

cat $HOME/.kube/config | base64

Make sure that your $HOME/.kube/config doesn't contain a AWS_PROFILE, i.e. remove the following section if it exists before doing the base64 encoding:

env:
- name: AWS_PROFILE
    value: github-actions
