Linux Containers (LXC) is a virtualization technology that allows multiple isolated Linux systems to run on a single host. It uses resource isolation features, such as cgroups and namespaces, to provide a lightweight virtualization solution. LXC also provides a rich set of tools and APIs for managing and configuring containers, contributing to its popularity as a containerization technology. By combining the advantages of LXC with the power of Docker, users can achieve a fully-fledged containerization experience in Linux systems.
LXC is a lightweight virtualization technology that uses resource isolation features of the Linux kernel to provide an isolated environment for applications. In LXC, images are manually built by creating a root filesystem and installing the necessary packages and configurations. Those containers are tied to the host system, may not be easily portable, and may require more technical expertise to configure and manage. LXC also provides some security features but may not be as robust as Docker.
Install LXC
ataker@htb[/htb]$ sudo apt-get install lxc lxc-utils -yOnce LXC is installed, we can start creating and managing containers on the Linux host. It is worth noting that LXC requires the Linux kernel to support the necessary features for containerization. Most modern Linux kernels have built-in support for containerization, but some older kernels may require additional configuration or patching to enable support for LXC.
Creating an LXC Container
To create a new LXC container, we can use the lxc-create command followed by the container’s name and the template to use. For example, to create a new Ubuntu container named linuxcontainer, we can use the following command:
ataker@htb[/htb]$ sudo lxc-create -n linuxcontainer -t ubuntu
