| 26 | 'pct' is a tool to manages Linux Containers (LXC). You can create and |
| 27 | destroy containers, and control execution |
| 28 | (start/stop/suspend/resume). Besides that, you can use pct to set |
| 29 | parameters in the associated config file, like network configuration |
| 30 | or memory. |
| 31 | |
| 32 | CLI Usage Examples |
| 33 | ------------------ |
| 34 | |
| 35 | Create a container based on a Debian template (provided you downloaded |
| 36 | the template via the webgui before) |
| 37 | |
| 38 | pct create 100 /var/lib/vz/template/cache/debian-8.0-standard_8.0-1_amd64.tar.gz |
| 39 | |
| 40 | Start container 100 |
| 41 | |
| 42 | pct start 100 |
| 43 | |
| 44 | Start a login session via getty |
| 45 | |
| 46 | pct console 100 |
| 47 | |
| 48 | Enter the LXC namespace and run a shell as root user |
| 49 | |
| 50 | pct enter 100 |
| 51 | |
| 52 | Display the configuration |
| 53 | |
| 54 | pct config 100 |
| 55 | |
| 56 | Add a network interface called eth0, bridged to the host bridge vmbr0, |
| 57 | set the address and gateway, while it's running |
| 58 | |
| 59 | pct set 100 -net0 name=eth0,bridge=vmbr0,ip=192.168.15.147/24,gw=192.168.15.1 |
| 60 | |
| 61 | Reduce the memory of the container to 512MB |
| 62 | |
| 63 | pct set -memory 512 100 |
| 64 | |

| 70 | Configuration file for the container <vmid> |
| 71 | |
| 72 | |
| 73 | Container Advantages |
| 74 | -------------------- |
| 75 | |
| 76 | - Simple, and fully integrated into {pve}. Setup looks similar to a normal |
| 77 | VM setup. |
| 78 | |
| 79 | * Storage (ZFS, LVM, NFS, Ceph, ...) |
| 80 | |
| 81 | * Network |
| 82 | |
| 83 | * Authentification |
| 84 | |
| 85 | * Cluster |
| 86 | |
| 87 | - Fast: minimal overhead, as fast as bare metal |
| 88 | |
| 89 | - High density (perfect for idle workloads) |
| 90 | |
| 91 | - REST API |
| 92 | |
| 93 | - Direct hardware access |
| 94 | |
| 95 | |
| 96 | Technology Overview |
| 97 | ------------------- |
| 98 | |
| 99 | - Integrated into {pve} graphical user interface (GUI) |
| 100 | |
| 101 | - LXC (https://linuxcontainers.org/) |
| 102 | |
| 103 | - cgmanager for cgroup management |
| 104 | |
| 105 | - lxcfs to provive containerized /proc file system |
| 106 | |
| 107 | - apparmor |
| 108 | |
| 109 | - CRIU: for live migration (planned) |
| 110 | |
| 111 | - We use latest available kernels (4.2.X) |
| 112 | |
| 113 | - image based deployment (templates) |
| 114 | |
| 115 | - Container setup from host (Network, DNS, Storage, ...) |
