Requirements

• LXD
• LVM / BTRFS / ZFS as container storage backend
• Python 3.4+
• Python packages described in requirements.txt

Installation

1. Configure your pool (we are using LVM) and linux bridge for your containers by running lxd init
2. Create a container, it will be your base container for the LXC pool
3. Install openssh-server inside the container and configure users
4. (Optional) Create a snapshot (ready-only snapshot as a base container is better) of your container
5. Change the source field in config/container.json to your container name (or snapshot name). Check https://lxd.readthedocs.io/en/latest/instances/ for more informations on LXD instance configuration
6. Copy config/container_ssh.json.example to config/container_ssh.json and configure it. This file describe informations used to connect to LXD containers via SSH.
7. Configure config/server.json - It describe SSH Server behaviors
8. Generate private RSA key and save it as private.pem
9. Run sshproxy.py

Installation details (Debian 10)

LXD installation

$ lxc snapshot debian-base snap

$ lxc exec debian-base /bin/bash
$ apt update && apt install openssh-server -y
$ passwd root
$ adduser debian
