That -way otherwise unprivileged users have possibility to manage containers without -needing a regular shell login on the container server. -.sp -For usage over SSH a unprivileged user should be created: -.nf - -.in +2 -sudo adduser \-\-gecos "compute\-tools,,," \e -.in +2 -\-\-home /var/lib/open\-infrastructure/container\-shell \e -\-\-shell /usr/bin/container\-shell -.in -2 -.in -2 -.fi -.sp -.sp -The container\-shell can then be allowed for specific SSH keys via -/var/lib/compute\-tools/container\-shell/.ssh/authorized_keys like so: -.nf - -.in +2 -command="/usr/bin/container\-shell",no\-port\-forwarding,no\-X11\-forwarding,\e -.in +2 -no\-agent\-forwarding,no\-pty ssh\-ed25519 [...] -.in -2 -.in -2 -.fi -.sp -.SS Restricted shell -.sp -The container\-shell by default grants any user that has access to it to use all available container commands. -.sp -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. -.SS Example (blacklisting) -.sp -In order to allow all commands except for removing and stopping containers, the -following variable can be used: -.nf - -.in +2 -command="CONTAINER_COMMANDS_DISABLE=\(aqremove stop\(aq \e -.in +2 -/usr/bin/container\-shell",no\-port\-forwarding,no\-X11\-forwarding,\e -no\-agent\-forwarding,no\-pty ssh\-ed25519 [...] -.in -2 -.in -2 -.fi -.sp -.SS Example (whitelisting) -.sp -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: -.nf - -.in +2 -command="CONTAINER_COMMANDS_ENABLE=\(aqlist version\(aq \e -.in +2 -/usr/bin/container\-shell",no\-port\-forwarding,no\-X11\-forwarding,\e -no\-agent\-forwarding,no\-pty ssh\-ed25519 [...] -.in -2 -.in -2 -.fi -.sp -.SH COMMANDS -.sp -All container commands are available, see container(1). Additionally, the -following commands are specific to container\-shell: -.INDENT 0.0 -.TP -.B about: -Shows introduction (manpage). -.TP -.B help: -Shows available commands within the container\-shell. -.TP -.B help COMMAND: -Shows help (manpage) for a specific container command. -.TP -.B logout, exit: -Exits container\-shell. -.UNINDENT -.SH SEE ALSO -.nf -compute\-tools(7), -container(1). -.fi -.sp -.SH HOMEPAGE -.sp -More information about compute\-tools and the Open Infrastructure project can be -found on the homepage (\fI\%https://open\-infrastructure.net\fP). -.SH CONTACT -.sp -Bug reports, feature requests, help, patches, support and everything else are -welcome on the Open Infrastructure Software Mailing List -<\fI\%software@lists.open\-infrastructure.net\fP>. -.sp -Debian specific bugs can also be reported in the Debian Bug Tracking System -(\fI\%https://bugs.debian.org\fP). -.SH AUTHORS -.sp -compute\-tools were written by Daniel Baumann -<\fI\%daniel.baumann@open\-infrastructure.net\fP> and others. -. |
