Creating LXD Container Profiles

A benefit of containers is the ability to create mass amounts of them in a short amount of time. LXD makes ensuring these containers all share the expected container-level instance configurations through the use of container profiles. In this hands-on lab, we will create a profile to use when deploying on a certain storage pool.

    Add a New Device to the New Profile

    Add a new device for containers deployed using the dbs profile:

    lxc profile device add dbs dbs disk path=/dbs source=/dbs
    
  3. Challenge

    Change Instance Settings

    Set the instance boot values using the CLI:

    lxc profile set dbs boot.autostart.priority 99
    lxc profile set dbs boot.stop.priority 1
    lxc profile set dbs snapshots.schedule "0 0 * * *"
    

    Confirm the changes:

    lxc profile show dbs
    
  4. Challenge

    Use Profile with Instances

    Create a test image:

    lxc launch alpine test -p dbs
    

    Then assign it to the existing db01 container; remove any additional profiles:

    lxc profile add db01 dbs
    lxc profile remove db01 default
