# Run a container with the AWS CLI on a specific node:
kubectl run -it debug --image amazon/aws-cli --command bash --overrides='{ "apiVersion": "apps/v1beta1", "spec": { "template": { "spec": { "nodeSelector": { "kubernetes.io/hostname": "<node-name>" } } } } }'

# Configure KIAM role:
kubectl run -it debug --image amazon/aws-cli --overrides='{"spec": {"template": {"metadata": {"annotations": {"iam.amazonaws.com/role": "my-cool-role"}}}}}' -- bash

I came across this from Google. Here's a quick oneliner for testing if your service account (& IAM role) for your IRSA setup works

$ kubectl run --rm -it debug --image amazon/aws-cli --command bash --overrides='{ "spec": { "serviceAccount": "my-cool-service-account" }  }'
