Run cloud-init locally with LXD (original) (raw)

LXD offers a streamlined user experience for using Linux system containers.
Create your configuration¶
In this example we will create a file called user-data.yaml containing a basic cloud-init configuration:
$ cat >user-data.yaml <<EOF #cloud-config password: password chpasswd: expire: False ssh_pwauth: True EOF
Initialize a container¶
With LXD, the following command initializes a container with the user data file we just created:
$ lxc init ubuntu-daily:jammy test-container $ lxc config set test-container user.user-data - < user-data.yaml $ lxc start test-container
To avoid the extra commands this can also be done at launch:
$ lxc launch ubuntu-daily:jammy test-container --config=user.user-data="$(cat user-data.yaml)"
Finally, a profile can be set up with the specific data if you need to launch this multiple times:
$ lxc profile create dev-user-data $ lxc profile set dev-user-data user.user-data - < cloud-init-config.yaml $ lxc launch ubuntu-daily:jammy test-container -p default -p dev-user-data
LXD configuration types¶
The above examples all show how to pass user data. To pass other types of configuration data use the configuration options specified below:
| Data | Configuration option |
|---|---|
| user-data | cloud-init.user-data |
| vendor-data | cloud-init.vendor-data |
| network config | cloud-init.network-config |
See the LXD Instance Configuration docs for more info about configuration values or the LXD Custom Network Configuration document for more about custom network config and using LXD with cloud-init.
