Introduction
LXC (Linux Containers) is an operating system level virtualization method for running several isolated Linux systems (containers) on a host running a linux operating system. The containers use the kernel of the host operating system and hence lxc does not have to virtualize the entire hardware of the host. Containers are relatively low on resource requirement and a singe host has the ability to run a very dense container environment, running several containers as opposed to a conventional KVM based virtualization. More information is available on here.
Preparing lxc Host
- ssh from local machine to the lxc host
ssh kedar@172.16.149.176
- Ensure infrabase1 (host server) is updated with latest patches and updates
sudo apt update && sudo apt upgrade -y
- Remove unwanted software
sudo apt autoremove
- Restart the host server
sudo init 6
Installing lxc
- Install lxc using the ubuntu repositories
sudo apt install lxc
