How to Install LXC on Elementary OS Latest

LXC is a lightweight Linux container that allows you to run multiple isolated Linux systems on a single host. In this tutorial, we will guide you through the process of installing LXC on Elementary OS Latest.

Prerequisites

Before we begin, make sure that your system is up to date by running the following command:

sudo apt update && sudo apt upgrade

Step 1: Install LXC

Run the following command to install LXC:

sudo apt install lxc

This command will install LXC and all its dependencies on your system.

Step 2: Verify the Installation

After the installation is complete, you can verify the installation by running the following command:

sudo lxc-ls --version

This command will display the version of LXC installed on your system.

Step 3: Create a Container

To create a container, first, we need to create a configuration file. Run the following command to create a configuration file named "my-container.conf":

sudo nano /etc/lxc/my-container.conf

Now copy and paste the following code into the configuration file and save it:

# Distribution configuration
lxc.include = /usr/share/lxc/config/common.conf
lxc.arch = linux64

# Container specific configuration
lxc.rootfs.path = dir:/var/lib/lxc/my-container/rootfs
lxc.uts.name = my-container
lxc.network.type = veth
lxc.network.link = lxcbr0
lxc.network.flags = up

This configuration file will create a container named "my-container", using the Arch Linux distribution and connecting it to a virtual Ethernet interface.

After creating the configuration file, run the following command to create the container:

sudo lxc-create -n my-container -f /etc/lxc/my-container.conf -t download -- --dist archlinux --release current --arch amd64

This command will download the Arch Linux distribution and install it in the container.

Step 4: Start the Container

To start the container, run the following command:

sudo lxc-start -n my-container -d

This command will start the container in a detached mode.

Step 5: Connect to the Container

To connect to the container, run the following command:

sudo lxc-attach -n my-container

This command will log you into the container.

Conclusion

In this tutorial, we have successfully installed LXC on Elementary OS Latest and created a container using Arch Linux distribution. You can now create multiple containers and run isolated Linux systems on your host.
