Proxmox Container Toolkit

=========================

|
|
'pct' is a tool to manages Linux Containers (LXC). You can create and
|
||
|
|
destroy containers, and control execution
|
||
|
|
(start/stop/suspend/resume). Besides that, you can use pct to set
|
||
|
|
parameters in the associated config file, like network configuration
|
||
|
|
or memory.

CLI Usage Examples
|
||
|
|
------------------
|
||
|
|
|
||
|
|
Create a container based on a Debian template (provided you downloaded
|
||
|
|
the template via the webgui before)
|
||
|
|
|
||
|
|
pct create 100 /var/lib/vz/template/cache/debian-8.0-standard_8.0-1_amd64.tar.gz
|
||
|
|
|
||
|
|
Start container 100
|
||
|
|
|
||
|
|
pct start 100
|
||
|
|
|
||
|
|
Start a login session via getty
|
||
|
|
|
||
|
|
pct console 100
|
||
|
|
|
||
|
|
Enter the LXC namespace and run a shell as root user
|
||
|
|
|
||
|
|
pct enter 100
|
||
|
|
|
||
|
|
Display the configuration
|
||
|
|
|
||
|
|
pct config 100
|
||
|
|
|
||
|
|
Add a network interface called eth0, bridged to the host bridge vmbr0,
|
||
|
|
set the address and gateway, while it's running
|
||
|
|
|
||
|
|
pct set 100 -net0 name=eth0,bridge=vmbr0,ip=192.168.15.147/24,gw=192.168.15.1
|
||
|
|
|
||
|
|
Reduce the memory of the container to 512MB
|
||
|
|
|
||
|
|
pct set -memory 512 100

Container Advantages
|
||
|
|
--------------------
|
||
|
|
|
||
|
|
- Simple, and fully integrated into {pve}. Setup looks similar to a normal
|
||
|
|
VM setup.
|
||
|
|
|
||
|
|
* Storage (ZFS, LVM, NFS, Ceph, ...)
|
||
|
|
|
||
|
|
* Network
|
||
|
|
|
||
|
|
* Authentification
|
||
|
|
|
||
|
|
* Cluster
|
||
|
|
|
||
|
|
- Fast: minimal overhead, as fast as bare metal
|
||
|
|
|
||
|
|
- High density (perfect for idle workloads)
|
||
|
|
|
||
|
|
- REST API
|
||
|
|
|
||
|
|
- Direct hardware access
|
||
|

Technology Overview
|
||
|
|
-------------------
|
||
|
|
|
||
|
|
- Integrated into {pve} graphical user interface (GUI)
|
||
|
|
|
||
|
|
- LXC (https://linuxcontainers.org/)
|
||
|
|
|
||
|
|
- cgmanager for cgroup management
|
||
|
|
|
||
|
|
- lxcfs to provive containerized /proc file system
|
||
|
|
|
||
|
|
- apparmor
|
||
|
|
|
||
|
|
- CRIU: for live migration (planned)
|
||
|
|
|
||
|
|
- We use latest available kernels (4.2.X)
|
||
|
|
|
||
|
|
- image based deployment (templates)
|
||
|
|
|
||
|
|
- Container setup from host (Network, DNS, Storage, ...)
