Automatic Registration of Clients Created by Terraform

Registering by leveraging cloud-init is the preferred way of automatic registering of the newly created virtual machines. This solution avoids configuring an SSH connection to the host. It can also be used regardless of the tool used for client creation.

User can pass the set of user data when deploying the image with Terraform, in order to automatically register the machine to SUSE Manager. user_data is run only once at bootstrap, and only the first time the machine is started.

Before using cloud-init to register clients, the user must configure:

This command will download the bootstrap script and register the new machine when it is created. It should be added to the cloud-init configuration:

The second solution for automatic registering of the newly created virtual machines uses Terraform’s remote-exec provisioner.

remote-exec provisioner interacts with the newly created machines. It opens an SSH connection and can run commands on that machine.

The remaining requirements are the same as when using cloud-init based client registration

This command will download the bootstrap script and register the new machine when it is created. It should be defined as the remote command to run:
