LXD is a system container and virtual machine manager.
It offers a simple CLI and REST API to manage local or remote instances, uses an image based workflow and support for a variety of advanced features.
Images are available for all Ubuntu releases and architectures as well as for a wide number of other Linux distributions. Existing integrations with many deployment and operation tools, makes it work just like a public cloud, except everything is under your control.
LXD containers are lightweight, secure by default and a great alternative to virtual machines when running Linux on Linux.
LXD virtual machines are modern and secure, using UEFI and secure-boot by default and a great choice when a different kernel or operating system is needed.
With clustering, up to 50 LXD servers can be easily joined and managed together with the same tools and APIs and without needing any external dependencies.
Supported configuration options for the snap (snap set lxd [<key>=<value>...]):
lxd init on initial startFor system-wide configuration of the CLI, place your configuration in /var/snap/lxd/common/global-conf/ (config.yml and servercerts)
Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap is available for CentOS 7.6+, and Red Hat Enterprise Linux 7.6+, from the Extra Packages for Enterprise Linux (EPEL) repository. The EPEL repository can be added to your system with the following command:
sudo yum install epel-release
Snap can now be installed as follows:
sudo yum install snapd
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install lxd, simply use the following command:
sudo snap install lxd
Browse and find snaps from the convenience of your desktop using the snap store snap.
