Timeout for Kubectl exec
You have a typo, try:
kubectl exec -it pod_name bash --request-timeout=0 -n testSee kubectl official documentation about request-timeout
--request-timeout string The length of time to wait before giving up on a single server request. Non-zero values should contain a corresponding time unit (e.g. 1s, 2m, 3h). A value of zero means don't timeout requests. (default "0")Note that "0" is already the default.
