Notes

• The configuration is intentionally kept quite static. Please create no PRs to make the configuration more flexible/dynamic.
• The OSISM documentation uses hostnames, examples, addresses etc. from OSISM Testbed.
• The third volume (/dev/sdd) is not enabled for Ceph by default. This is to test the scaling of Ceph.
• The manager is used as pull through cache for Docker images and Ubuntu packages. This reduces the amount of traffic consumed.

Supported releases

The following stable Ceph and OpenStack releases are supported.

The deployment of Ceph is based on ceph-ansible.

• Ceph Quincy (default)
• Ceph Reef
• Ceph Squid

The deployment of OpenStack is based on kolla-ansible.

• OpenStack 2023.1
• OpenStack 2023.2
• OpenStack 2024.1 (default)

The deployment of Kubernetes is based on k3s-ansible.

• Kubernetes v1.30 (default)
