Ceph deployment for Dimension Data's MCP

Terraform configuration and Ansible playbooks to deploy Ceph in MCP 2.0.

If you have questions, requests, or would like to contribute, please please create an issue because we'd love to hear from you :-)

Getting started

1. python ansible/patch-ceph.py
2. Customise terraform/main.tf and *.yml in ansible/ceph/group_vars as required
3. Run curl https://api.ipify.org, and add the resulting IP address to terraform/terraform.tfvars as client_ip (create this file if it does not already exist)
4. cd terraform
5. terraform apply
6. terraform refresh
7. cd ../ansible/ceph
8. ansible-playbook ../playbooks/01_ansible_bootstrap.yml
9. ansible all -m ping
10. ansible-playbook ../playbooks/02_server_init.yml
11. ansible-playbook ceph.yml

Notes

• To ensure a new (from-scratch) cluster deployment, before you start ensure that the ansible/ceph/fetch directory is not already present.
• Additional roles can be added to the monitor or OSD nodes by customising the roles key under ddcloud_server in terraform/mon_nodes.tf and / or terraform/osd_nodes.tf.
  For a list of valid roles, see ansible/ceph/ceph.yml.
