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.

Challenge

Create a New Profile
Create new storage pool based on the default profile by copying the profile:
```
lxc profile copy default dbs
```
Challenge

Update the Storage Pool
Edit the file so the appropriate storage pool is used when a container is deployed:
```
lxc profile edit dbs
```
```
config: {}
description: Default LXD profile
devices:
  eth0:
    name: eth0
    nictype: bridged
    parent: lxdbr0
    type: nic
  root:
    path: /
    pool: dbs
    type: disk
name: dbs
used_by: []
```
We can then continue by adding the other configurations into this file directly, or save and exit and set them via the CLI.

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

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
```
