sikalabs-kubernetes-oidc-login

What is sikalabs-kubernetes-oidc-login ?

sikalabs-kubernetes-oidc-login is a simple command-line tool that performs OIDC login and outputs Kubernetes ExecCredential for kubectl. It allows users to authenticate with an OIDC provider and obtain the necessary credentials to access Kubernetes clusters.

This project has been heavily inspired by int128/kubelogin.
