terraform-openstack-learninglab

Build your learning lab on OpenStack

This module will spawn instances, create users and optionnaly set up a OCFS2 drive.

⚠️ Shared drive details

Requirements

• A ceph volume type supporting multiattach
• An OS image featuring OCFS2 services and kernel modules

Usage

To avoid any data loss, the Cinder volume lifecyle is set to prevent_destroy. It means that you won't be able to apply a plan that results in a volume destruction. To tear down the infrastructure, remove the volume from state first :

terraform state rm openstack_blockstorage_volume_v3.ocfs2[0]
terraform destroy

Orphaned volume can be later manually destroyed or reused in future infrastructure via volume_id variable.
