Linux Containers (LXC) are managed by LXD as if they were Virtual Machines, allowing them to take\u00a0<\/span>snapshots<\/span><\/strong>, have\u00a0<\/span>distinct IPs<\/span><\/strong>, and the content\u00a0<\/span>data is not lost when the container is shutdown<\/span><\/strong>.<\/span><\/p>\n

Containers can be managed using profiles to define network and other configuration parameters such as limiting the maximum amount of CPU or RAM used by a single instance.<\/span><\/p>\n

It is worth mentioning that since Canonical took full control of the LXD project, the community created a fork called Incus<\/strong> [Link<\/a>]. This fork has removed many of Canonical’s ecosystem-specific components from the code. Incus is the adopted fork of the LinuxContainers.org<\/strong> [Link<\/a>].<\/p>\n

Internally, the containers can communicate using\u00a0<\/span>containerName.lxd<\/span><\/strong>\u00a0because there is a domain name service set up by default.<\/span><\/p>\n

LXD vs Docker<\/span><\/p>\n

While LXD is a system container type that contains a whole operating system functionality, Docker is an application container type that usually only runs single applications and abstracts storage, network, logs… from the user.<\/span><\/p>\n

INSTALLATION<\/strong><\/p>\n

The second command line (optional) enables the Web-UI.<\/p>\n

sudo snap install lxd\r\nsudo snap set lxd ui.enable=true\r\nsudo systemctl reload snap.lxd.daemon.service\r\nsudo usermod -aG lxd yourUserName\r\nsudo lxd init<\/pre>\n
Note:<\/span><\/strong>\u00a0it is not necessary but is recommended to add your user to the lxd group to allow manipulating the containers without using sudo every time. It might require logging out and back in again to apply to the new group.<\/span><\/p>\n
WEB-UI SETUP<\/strong><\/p>\n
The Web-UI is only available from the version LXD 5.14<\/strong> or newer. Navigate to https:\/\/127.0.0.1:8443\/<\/strong> from the the local machine or add the network address if from a remote:<\/p>\n
