-NAME
-----
-container-shell - Manage systemd-nspawn containers (shell)
-
-
-SYNOPSIS
---------
-*container-shell*
-
-
-DESCRIPTION
------------
-compute-tools provides the system integration for managing containers using systemd-nspawn.
-
-
-COMMANDS
---------
-All container commands are available, see container(1). Additionally, the following commands are specific to container-shell:
-
-*about:*::
-	shows introduction (manpage).
-
-*help:*::
-	shows available commands within the container-shell.
-
-*help COMMAND:*::
-	shows help (manpage) for a specific container command.
-
-*logout*, *exit:*::
-	exits container-shell.
-
-USAGE
------
-Although the container-shell can be started from a running system like any other program, the main intend is to use the
-container-shell via SSH. That way otherwise unprivileged users have possibility to manage containers without
-needing a regular shell login on the container server.
-
-For usage over SSH a unprivileged user should be created:
-
-  sudo adduser --gecos "compute-tools,,," \
-	--home /var/lib/open-infrastructure/container-shell \
-	--shell /usr/bin/container-shell
-
-The container-shell can then be allowed for specific SSH keys via /var/lib/open-infrastructure/container-shell/.ssh/authorized_keys like so:
-
-  command="/usr/bin/container-shell",no-port-forwarding,no-X11-forwarding,no-agent-forwarding,no-pty ssh-ed25519 [...]
-
-
-RESTRICTED SHELL
-----------------
-The container-shell by default grants any user that has access to it to use all available container commands.
-
-Through two corresponding environment variables users can be allowed or disallowed to use specific container commands.
-In connection with SSH this makes it possible to grant certain SSH keys (and by that, users) privileges to operate container
-servers without having to give them root access, a login shell at all and prevents them from doing things they are not trusted to do.
-
-Example (blacklisting): In order to allow all commands except for removing and stopping containers, the following variable can be used:
-
-  command="CONTAINER_COMMANDS_DISABLE='remove stop' /usr/bin/container-shell",no-port-forwarding,no-X11-forwarding,no-agent-forwarding,no-pty ssh-rsa [...]
-
-Example (whitelisting): The other way around works too. To disallow all commands except for listing containers and showing the compute-tools version, the following variable can be used:
-
-  command="CONTAINER_COMMANDS_ENABLE='list version' /usr/bin/container-shell",no-port-forwarding,no-X11-forwarding,no-agent-forwarding,no-pty ssh-rsa [...]
