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 [...] - - -SEE ALSO --------- -machinectl(1), -systemd-nspawn(1). - - -HOMEPAGE --------- -More information about compute-tools and the Open Infrastructure project can be found on the homepage at https://open-infrastructure.net. - - -CONTACT -------- -Bug reports, feature requests, help, patches, support and everything else -are welcome on the Open Infrastructure Software Mailing List <software@lists.open-infrastructure.net>. - -Debian specific bugs can also be reported in the Debian Bug Tracking System at https://bugs.debian.org. - - -AUTHORS -------- -compute-tools were written by Daniel Baumann <daniel.baumann@open-infrastructure.net> and others. |
