Accordingly with the kubectl help documentation for the logs
command, the container name is a flag and not an argument:
`
Usage:
kubectl logs [-f] [-p] (POD | TYPE/NAME) [-c CONTAINER] [options]
`
The use of an argument instead of a flag is to keep compatible
with legacy systems, but it is not recommended as it can be removed
at any time.
