aws eks update-kubeconfig --name EKS_cluster

It is giving me this error

aws: error: argument operation: Invalid choice, valid choices are:

From the docs of creating a kubeconfig for Amazon EKS here

Ensure that you have version 1.16.156 or later of the AWS CLI installed.

Clearly this is because of older version(1.15.58) of CLI. Upgrading the CLI should solve this issue.

Also now the CLI has got version 2 which you can install from here

Your version of the AWS-CLI needs to be updated. At the very least you need to be running AWS-CLI version 1.16.156 as mentioned in the AWS Docs.

Amazon EKS uses the aws eks get-token command, available in version 1.16.156 or later of the AWS CLI or the AWS IAM Authenticator for Kubernetes with kubectl for cluster authentication.

You'll also need to make sure you have AWS IAM Authenticator installed in order to authenticate using roles.

Download the Amazon EKS-vended aws-iam-authenticator binary from Amazon S3. To download the ARM version, change amd64 to arm64 before running the command. curl -o aws-iam-authenticator https://amazon-eks.s3.us-west-2.amazonaws.com/1.17.7/2020-07-08/bin/linux/amd64/aws-iam-authenticator

Apply execute permissions to the binary. chmod +x ./aws-iam-authenticator

Copy the binary to a folder in your $PATH. We recommend creating a $HOME/bin/aws-iam-authenticator and ensuring that $HOME/bin comes first in your $PATH. mkdir -p $HOME/bin && cp ./aws-iam-authenticator $HOME/bin/aws-iam-authenticator && export PATH=$PATH:$HOME/bin

Add $HOME/bin to your PATH environment variable. echo 'export PATH=$PATH:$HOME/bin' >> ~/.bashrc

Test that the aws-iam-authenticator binary works. aws-iam-authenticator help
