Explanation

The explanatory guides in this section discuss the concepts used in LXD and help you understand how things fit together.

Important concepts

LXD’s core concepts include its relationship with LXC and the instance types it supports: system containers and virtual machines.

• lxd and lxc
• Containers and VMs

Entities in LXD

LXD uses several distinct entity types, including images, storage pools, networks, and projects. To learn how to use them, refer to the How-to guides.

• Local and remote images
• Storage pools, volumes, and buckets
• Networking setups
• The LXD Dqlite database
• lxc show and info

Access management

LXD supports multiple methods for authenticating remote API clients and provides fine-grained authorization controls. Projects can also be used to scope and restrict access.

• Remote API authentication
• Remote API authorization
• Instances grouping with projects

Production setup

For scalable, reliable, and secure LXD deployments, these guides help you understand the key concepts around clustering, performance tuning, and security.

• Clusters
• Replicators
• Performance tuning
• Security
• Privilege delegation using BPF Token
