## Container Creation

- Create a new container:
  ```
  pct create <vmid> <ostemplate> [OPTIONS]
  ```
  - `<vmid>`: The ID of the new container (integer).
  - `<ostemplate>`: The path or name of the OS template to use for the container.

- Example:
  ```
  pct create 101 /var/lib/vz/template/cache/openwrt-rootfs.tar.xz --unprivileged 1 --arch amd64 --ostype unmanaged --hostname openwrt-0 --storage local-lvm --net0 name=eth0,bridge=vmbr0,firewall=1 --net1 name=eth1,bridge=vmbr1,firewall=1
  ```

## Container Management

- Start a container: `pct start <vmid>`
- Stop a container: `pct stop <vmid>`
- Restart a container: `pct restart <vmid>`
- Shutdown a container: `pct shutdown <vmid>`
- Destroy a container: `pct destroy <vmid>`
- Clone a container: `pct clone <vmid> <newvmid>`
- Migrate a container: `pct migrate <vmid> <target-node>`
- Resize a container's disk: `pct resize <vmid> <disk> <size>`

## Container Configuration

- Update container configuration: `pct config <vmid> [OPTIONS]`
- Set container description: `pct set <vmid> --description <text>`
- Set container memory: `pct set <vmid> --memory <size>`
- Set container CPU cores: `pct set <vmid> --cores <number>`
- Set container boot order: `pct set <vmid> --boot <order>`
- Add a network device: `pct set <vmid> --net<N> name=<name>,bridge=<bridge>,firewall=<1|0>`
- Add a mount point: `pct set <vmid> --mp<N> <volume>`

## Container Snapshots

- Create a snapshot: `pct snapshot <vmid> <snapname>`
- List snapshots: `pct listsnapshot <vmid>`
- Restore a snapshot: `pct rollback <vmid> <snapname>`
- Delete a snapshot: `pct delsnapshot <vmid> <snapname>`

## Container Backup and Restore

- Backup a container: `vzdump <vmid> --mode snapshot --compress gzip --storage <storage>`
- Restore a container: `pct restore <vmid> <backup-file>`

## Container Monitoring

- Show container status: `pct status <vmid>`
- Show container resource usage: `pct top <vmid>`
- Show container logs: `pct log <vmid>`

## Common Options

- `--unprivileged 1`: Run the container as an unprivileged user.
- `--arch <arch>`: Set the container architecture (e.g., amd64, i386).
- `--ostype <type>`: Set the OS type (e.g., debian, ubuntu, unmanaged).
- `--hostname <name>`: Set the container hostname.
- `--storage <storage>`: Set the storage for the container.
- `--net<N>`: Configure network devices for the container.
- `--cpu <cpu>`: Set the CPU type for the container.
- `--memory <size>`: Set the memory size for the container.
- `--swap <size>`: Set the swap size for the container.
- `--rootfs <volume>`: Set the root filesystem for the container.

This cheatsheet covers the essential commands and options for creating and managing LXC containers in Proxmox using the `pct` command. It includes examples of container creation, management, configuration, snapshots, backup/restore, and monitoring.

Remember to replace `<vmid>`, `<ostemplate>`, and other placeholders with actual values when using the commands. Adjust the options and parameters according to your specific requirements and environment.
