Cleura Cloud Launch Pad (OpenTofu)

Prerequisites

You’ll need the tofu command from OpenTofu available on your system.

There are multiple ways to install OpenTofu on your system. Please refer to the installation instructions for details.

Configuration

In order to build your Launch Pad, you need an OpenTofu configuration.

Your OpenTofu configuration is in the .tf files contained in the tf subdirectory of your checkout. Do not modify these files.

Variables

The configuration supports multiple variables, where all but one have a reasonable default value.

You set the variables for your Launch Pad in the file vars.tfvars. Specifically, you need to set the variable ssh_public_key to your public SSH key:

ssh_public_key = "ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIL/Gftxrp74jLZJAxmM5ei6Vvq9lHv18DDWws1O9hckX john.doe@example.com"

Be sure to replace the value with your SSH public key.

Environment variables

To build your Launch Pad, you need to set OS_* environment variables as described in the Accessing the OpenStack API section in Cleura Docs.

Initialising the provider

The OpenTofu configuration relies on the openstack provider, which you must initialise before applying the configuration for the first time.

You do this with the following command:

tofu init

Provider initialisation should take no more than a few seconds.

Building your Launch Pad

Once you have installed the prerequisite packages, populated your vars.tfvars file, set the correct OS_* environment variables, and initialised the provider, you can build your Launch Pad with the following command:

tofu apply -var-file="vars.tfvars"

Building your Launch Pad should take just a few minutes.

Accessing your Pad Ramp

Once tofu apply has completed, you can use the tofu state show command to show your Pad Ramp’s public (“floating”) IP address:

$ tofu state show openstack_networking_floatingip_v2.floating_ip 
# openstack_networking_floatingip_v2.floating_ip:
resource "openstack_networking_floatingip_v2" "floating_ip" {
    address   = "192.0.2.146"
    [...]
}

You can then use the ssh command to test connectivity:

$ ssh cleura@192.0.2.146
[...]
Please login as the user "ubuntu" rather than the user "cleura".

The correct login name will differ based on the base operating system image. You can then reconnect using the correct username:

$ ssh ubuntu@192.0.2.146
Welcome to Ubuntu 24.04.4 LTS (GNU/Linux 6.8.0-101-generic x86_64)
[...]
