| 27 | 'pct' is a tool to manages Linux Containers (LXC). You can create and | |
| 28 | destroy containers, and control execution | |
| 29 | (start/stop/suspend/resume). Besides that, you can use pct to set | |
| 30 | parameters in the associated config file, like network configuration | |
| 31 | or memory. | |
| 32 | ||
| 33 | CLI Usage Examples | |
| 34 | ------------------ | |
| 35 | ||
| 36 | Create a container based on a Debian template (provided you downloaded | |
| 37 | the template via the webgui before) | |
| 38 | ||
| 39 | pct create 100 /var/lib/vz/template/cache/debian-8.0-standard_8.0-1_amd64.tar.gz | |
| 40 | ||
| 41 | Start container 100 | |
| 42 | ||
| 43 | pct start 100 | |
| 44 | ||
| 45 | Start a login session via getty | |
| 46 | ||
| 47 | pct console 100 | |
| 48 | ||
| 49 | Enter the LXC namespace and run a shell as root user | |
| 50 | ||
| 51 | pct enter 100 | |
| 52 | ||
| 53 | Display the configuration | |
| 54 | ||
| 55 | pct config 100 | |
| 56 | ||
| 57 | Add a network interface called eth0, bridged to the host bridge vmbr0, | |
| 58 | set the address and gateway, while it's running | |
| 59 | ||
| 60 | pct set 100 -net0 name=eth0,bridge=vmbr0,ip=192.168.15.147/24,gw=192.168.15.1 | |
| 61 | ||
| 62 | Reduce the memory of the container to 512MB | |
| 63 | ||
| 64 | pct set -memory 512 100 | |
| 65 | ||
| 66 | Files | |

| 71 | Configuration file for the container <vmid> | |
| 72 | ||
| 73 | ||
| 74 | Container Advantages | |
| 75 | -------------------- | |
| 76 | ||
| 77 | - Simple, and fully integrated into {pve}. Setup looks similar to a normal | |
| 78 | VM setup. | |
| 79 | ||
| 80 | * Storage (ZFS, LVM, NFS, Ceph, ...) | |
| 81 | ||
| 82 | * Network | |
| 83 | ||
| 84 | * Authentification | |
| 85 | ||
| 86 | * Cluster | |
| 87 | ||
| 88 | - Fast: minimal overhead, as fast as bare metal | |
| 89 | ||
| 90 | - High density (perfect for idle workloads) | |
| 91 | ||
| 92 | - REST API | |
| 93 | ||
| 94 | - Direct hardware access | |
| 95 | ||
| 96 | ||
| 97 | Technology Overview | |
| 98 | ------------------- | |
| 99 | ||
| 100 | - Integrated into {pve} graphical user interface (GUI) | |
| 101 | ||
| 102 | - LXC (https://linuxcontainers.org/) | |
| 103 | ||
| 104 | - cgmanager for cgroup management | |
| 105 | ||
| 106 | - lxcfs to provive containerized /proc file system | |
| 107 | ||
| 108 | - apparmor | |
| 109 | ||
| 110 | - CRIU: for live migration (planned) | |
| 111 | ||
| 112 | - We use latest available kernels (4.2.X) | |
| 113 | ||
| 114 | - image based deployment (templates) | |
| 115 | ||
| 116 | - Container setup from host (Network, DNS, Storage, ...) | |
