Installing LXD (Linux container hypervisor) on Ubuntu 20.04 LTS using the apt package manager is a simple process and can be done by following these steps:
- First, update the package list by running the command:
sudo apt update
- Next, you need to install the LXD package and its dependencies by running the command:
sudo apt install lxd
- After the installation is complete, you need to initialize the LXD configuration by running the command:
sudo lxd init
- The
lxd initcommand will guide you through a series of prompts to configure various settings, such as storage pool, network interface, and IP address allocation. You can use the default values, or you can customize them according to your needs. - Once the initialization is complete, you can start creating and managing containers by using the
lxccommand. For example, to create a new container, you can run the command:
sudo lxc launch ubuntu:20.04 mycontainer
- You can check the list of existing containers by running the command:
sudo lxc list
- And you can check the status of a specific container by running the command:
sudo lxc info mycontainer
- To access the shell of a container, you can run the command:
sudo lxc exec mycontainer -- /bin/bash
After installation, it is good to know that, LXD uses AppArmor and SELinux to provide security isolation between containers. Also, make sure you have enough storage and memory to run the containers.
