A tool to automate Kubernetes user creation using the native Go client

Kubernetes Automatic User Creator

The purpose of this tool is to automate the process of generating Certificate Signing Request, sending it to the API server, approving and downloading the certificate. The program generates the necessary Kube Config file that contains the user certificate and key. This file can then be handed to the user to use for authentication. The program uses the current Kube Config file, either ~/.kube/config or the one defined in the KUBECONFIG environment variable.

Usage:

./k8suser --username myuser --email myuseremail --cluster clusername --country US --city IL --organization acmecorp --orgUnit DevOps --province Chicago

The command-line option can be explained as follows: --outdir: The directory where you want the generated KUBECONFIG to be placed (defaults to the current working diectory) --username: The name used for authentication (Required)

--email: The user's email (Required)

--cluser: The name of the cluster (Required). The program uses this name to extract the relevent information from the Kube Config file
