About

This module provisions a custom server on OpenStack.

It offers a streamlined process for:

• Instantiating an OpenStack VM with specified flavors and image sources.
• Assigning a network port and server group to the VM.
• Setting up SSH access through specified key pairs.
• Optionally installing dependencies via cloud-init.
• Extending cloud-init with custom configurations for advanced setup.

Usage

Input Variables

• name: Name to give to the VM. Used for identification within OpenStack.
• network_port: Network port to assign to the VM. Should be of type openstack_networking_port_v2.
• cephfs_network_port: CephFS network port to assign to the node. Should be of type openstack_networking_port_v2 or null if not used.
• server_group: Server group to assign to the VM. Should be of type openstack_compute_servergroup_v2.
• image_source: Source of the VM's image. Provide either an image_id (for image-based VMs) or a volume_id (for volume-based VMs), but not both. The object structure is:
  • image_id: String ID of the image to use.
  • volume_id: String ID of the volume to use.
• flavor_id: ID of the VM flavor. Specifies the compute, memory, and storage capacity of the VM.
• keypair_name: Name of the keypair used for SSH access to the VM.
• install_dependencies: Boolean flag to determine whether to install all dependencies in cloud-init. Defaults to true.
• cloud_init_configurations: List of additional cloud-init configurations. Each entry should include:
  • filename: A unique and descriptive filename for the cloud-init part.
  • content: The content of the cloud-init configuration.

Example of a Custom Cloud-Init Part

If you want to perform custom operations during the VM setup, like installing additional software, you can use the cloud_init_configurations variable. For example, to install and configure cephadm:

cloud_init_configurations = [
  {
    filename = "cephadm.cfg"
    content  = <<-EOF
      #cloud-config
      runcmd:
        - apt-get update
        - apt-get install -y cephadm
        - cephadm init
      EOF
  }
]
