kubectl run "$name" -it --rm --image="$image" --labels="$labels" --restart=Never --overrides="$overrides" "$@"

Good and simple workaround solution until kubectl provides the ability (which will most likely be never...) to run kubernetes pod manifests interactively.

However, beware as this does not take into account:

• volumes
• env vars
• command override
• args

A lot of parsing is still needed to actually correctly convert a usual pod manifest into a kubectl run command.
