589 | pct - Tool to manage Linux Containers (LXC) on Proxmox VE | |
590 | ||
591 | =head1 SYNOPSIS | |
592 | ||
593 | =include synopsis | |
594 | ||
595 | =head1 DESCRIPTION | |
596 | ||
597 | pct is a tool to manages Linux Containers (LXC). You can create | |
598 | and destroy containers, and control execution | |
599 | (start/stop/suspend/resume). Besides that, you can use pct to set | |
600 | parameters in the associated config file, like network configuration or | |
601 | memory. | |
602 | ||
603 | =head1 EXAMPLES | |
604 | ||
605 | Create a container based on a Debian template | |
606 | (provided you downloaded the template via the webgui before) | |
607 | ||
608 | pct create 100 /var/lib/vz/template/cache/debian-8.0-standard_8.0-1_amd64.tar.gz | |
609 | ||
610 | Start a container | |
611 | ||
612 | pct start 100 | |
613 | ||
614 | Start a login session via getty | |
615 | ||
616 | pct console 100 | |
617 | ||
618 | Enter the lxc namespace and run a shell as root user | |
619 | ||
620 | pct enter 100 | |
621 | ||
622 | Display the configuration | |
623 | ||
624 | pct config 100 | |
625 | ||
626 | Add a network interface called eth0, bridged to the host bridge vmbr0, | |
627 | set the address and gateway, while it's running | |
628 | ||
629 | pct set 100 -net0 name=eth0,bridge=vmbr0,ip=192.168.15.147/24,gw=192.168.15.1 | |
630 | ||
631 | Reduce the memory of the container to 512MB | |
632 | ||
633 | pct set -memory 512 100 | |
