AWS EKS kubectl config updater

The AWS EKS update-kubeconfig command does a terrible job in updating your kubectl configuration file when your using the same cluster for multiple roles and namespaces like we do for access authorization. This script will update your kubectl config file for use with AWS EKS per role/namespace.

Requirements

You need at least Python 3.

Install

To install the script, use the following command:

wget -qO - https://raw.githubusercontent.com/xip-online-applications/kubectl-updater-aws/master/install.sh | bash

Usage

Use the command in the following way:

kubectl-updater-aws -c <cluster_name>

It supports the following arguments:

Argument	Shortcut	Required	Description	Default
--cluster	-c	✓	The cluster name to use
--role-arn	-r		The role ARN to assume
--config-file	-f		The kubectl config file to use	~/.kube/config
--namespace	-n		The namespace to authenticate with
--aws-profile	-p		The AWS profile to use

Examples

Connect with role and namespace:

kubectl-updater-aws -c test -r arn:aws:iam::123456789:role/test-application-role -n test-application-namespace

Connect with namespace only:

kubectl-updater-aws -c prod -n prod-namespace
