LXC is an operating-system-level virtualization method for running multiple isolated Linux systems on a control host using a single Linux kernel.

Install

sudo apt install -y lxc lxc-templates

check the LXC using the following command:

lxc-checkconfig

Create LXC Container

LXC comes with lots of ready-made templates. List them with

ls /usr/share/lxc/templates/

create your first container

sudo lxc-create --template download --name u1
lxc-create -n new-container -t ubuntu

This will interactively ask for a container root filesystem type to download – in particular the distribution, release, and architecture. To create the container non-interactively, you can specify these values on the command line:

sudo lxc-create -t download -n u1 -- --dist ubuntu --release DISTRO-SHORT-CODENAME --arch amd64
# or
sudo lxc-create -t download -n u1 -- -d ubuntu -r DISTRO-SHORT-CODENAME -a amd64

List containers:

lxc-ls

Start Container

lxc-start -n new-container -d

take a console of the container

lxc-console -n new-container

get the details of the running container

lxc-info -n new-container

start and stop the container

lxc-start -n new-container
lxc-stop -n new-container

Pause and Unpause the container

lxc-freeze -n new-container
lxc-unfreeze -n new-container

You can also take a snapshot of the container

# First stop the container
lxc-stop -n new-container

# take a snapshot of the container
lxc-snapshot -n new-container

# see the location of the snapshot
lxc-snapshot -L -n new-container

# You can restore the snapshot using
lxc-snapshot -r snap0 -n new-container

to delete the container

lxc-stop -n new-container
lxc-destroy -n new-container
