LXD provides mirroring for linux distributions, supports multiple storage backends and network types, and is known as the Next Generation Container and Virtual Machine Manager, providing an immersive experience for running linux systems in containers or as virtual machines. It enables users to manage containers and virtual machines in a variety of ways, including lxc clients or command lines, REST apis, and even third-party integrations.

LXD is an image-based image suitable for linux distributions. Provide REST apis and lxc command tools to interact with containers and provide support for various storage backends, storage volumes, and storage pools. Network management is achieved by creating bridging networks and cross-host tunnels. Advanced control of resources such as CPU, RAM, disk usage, block I/O, and kernel. Flexible and scalable, you can deploy containers on servers and configure a cluster that can aggregate thousands of containers on individual nodes.

LXD is different from LXC, which is the operating system virtualization technology left behind by linux containers, with powerful apis and other senses that allow users to seamlessly create and manage containers/virtual machines in a single server. LXC consists of templates, tool languages, and library bindings. Create and manage LXC containers on the linux distribution of RHEL. Update the package before setting SElinux to permissive mode:

$ sudo dnf update

Set tolerance mode:

$ sudo sed -i 's/^SELINUX=.*/SELINUX=permissive/g' /etc/selinux/config

To restart the server:

$ sudo reboot

Confirm the SElinux status:

$ getenforce

To install the EPEL repository:

$ sudo yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm

perhaps

$ sudo yum install epel-release

Switch to the root user:

$ su -

Add parameters:

$ grubby --args="user_namespace.enable=1" --update-kernel="$(grubby --default-kernel)"

$ grubby --args="namespace.unpriv_enable=1" --update-kernel="$(grubby --default-kernel)"

$ echo "user.max_user_namespaces=3883" | sudo tee -a /etc/sysctl.d/99-userns.conf

Continue enabling Snap. Installing LXD in RHEL8 can be done directly with the snap package:

$ sudo dnf install snapd

To install the snapd daemon or service and other Python dependencies:

sudo dnf install snapd

Continue to enable the main snap communication socket after installation:

$ sudo systemctl enable --now snapd.socket

Create a symbolic link from /var/lib/snapd/snap to /snap to enable classic support.

$ sudo ln -s /var/lib/snapd/snap /snap

Restart system update Capture path:

$ sudo reboot

Install LXD:

$ sudo snap install —-classic lxd

To install the LTS version:

$sudo snap install lxd --channel=4.0/stable

If you do not want to switch to sudo user to execute lxc directly, you can add the current user to the lxd group:

$ sudo usermod -aG lxd $USER

Verify that the addition of the user is complete by listing all the groups to which the user belongs:

$ groups tecmint

Run newgrp (change the current group ID during the login session, setting the current group ID to named group lxd) :

$ newgrp lxd

After creating and managing LXD container money, use the command to initialize the LXD environment:

$ lxc init

You can set the environment or apply the default Settings.
