Authentication

This repo includes a kubeconfig, which is configured for the test cluster. It will authenticate users through OIDC.

Prerequisites

For the OIDC flow to work, you will need to have kubelogin installed. Summarizing the installation instructions here:

# Homebrew (macOS and Linux)
brew install int128/kubelogin/kubelogin

# Krew (macOS, Linux, Windows and ARM)
kubectl krew install oidc-login

# Chocolatey (Windows)
choco install kubelogin

Access Cluster

export KUBECONFIG=$(pwd)/environments/test/kube.conf"

kubectl get nodes
kubectl get pods --all-namespaces

Enjoy!
