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

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
```

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
```
