LXC (Linux Containers)

LXC (Linux Containers) is a lightweight virtualization technology that allows running multiple isolated Linux systems (containers) on a single host. LXC is a userspace interface for the Linux kernel’s cgroups and namespaces, providing an operating system-level virtualization solution.

Unlike traditional virtualization, which involves running separate virtual machines, LXC containers share the host’s kernel but provide isolated environments for running applications, making them faster and more efficient.

Basic Structure of LXC

LXC provides a set of tools to create, manage, and operate containers. It allows you to:

• Create containers from prebuilt images

• Manage their lifecycle (start, stop, restart, delete)

• Configure networking, file systems, and resource limits

• Provide isolation for processes and file systems

Main LXC Commands and Subcommands

Here are the key LXC commands and their associated subcommands:

1. lxc-create

This command is used to create a new container from a specified template.

Syntax

lxc-create -n <container_name> -t <template>

• -n <container_name>: Specifies the name of the container.

• -t
