exec-scoped runs the specified command (e.g. a script) against an instance, after
first setting the environment variables that the selected services expect — for
example DOCKER_HOST for docker, or KUBECONFIG for kubernetes. This makes it
possible to point an existing script or tool at a Namespace instance’s Docker or
Kubernetes endpoint without manually exporting those variables yourself.
Which services get wired up is controlled with --service. The corresponding
environment variables are only set for the lifetime of the child process that
exec-scoped starts; they aren’t exported into your interactive shell.

list to set up environment variables for more than one service at once — for

before running <cmd...>.
