About Kubernetes Authentication
Too Long; Didn't Read Kubernetes uses authentication, Authorization and Admission to enforce security access and permissions. There are 3 steps that are taken in the authentication process. The first thing in Authentication is Identity, Identity and Identity Identity Identity. The two minimal methods required are - Service account tokens for service accounts and at least one other method of user authentication. The API server reads bearer tokens from a file when given the option "Bearer" on the command line. The token list cannot be changed without restarting the API server, and the token list can't be changed.
