Manage runtime environments. A runtime environment pairs a base container image with an optional setup script. Like container-image, every command identifies its target with --owner and --name flags rather than a positional argument.

list

get

Shows an environment, including its setup script. --owner and --name are both required.

create

--owner and --name are required. Supply the base image with --image, or omit it in a terminal to pick from a searchable list.

modify

--owner and --name identify the environment; pass at least one of the remaining options.

test

Provisions a throwaway container from the environment, streams the setup script’s logs, and reports whether the container came up. Use it to check a setup script before an agent depends on it.
--image and -i, --interactive cannot be combined. --interactive needs a terminal and is rejected in machine-readable mode, so in a script or CI job pass --image explicitly. On modify, --setup and --clear-setup are likewise mutually exclusive.
