Motivation:

Deploy a ceph cluster with terraform backends and provisioning with config management tools.

Currently we support following terraform backends:

• libvirt terraform-plugin. (https://github.com/dmacvicar/terraform-provider-libvirt)

Currently we support following provisioning tools:

• saltstack.
• ansible.

Install:

You need to install terraform https://www.terraform.io/ and https://github.com/dmacvicar/terraform-provider-libvirt.

For the config management you will need to have saltstack or ansible installed on the machine executing the states/playbook.

Examples:

Have a look at examples

Design-Architecture:

For explanation, remarks about the current Architecture design, have a look here architecture

Deploy:

Take an example.tf file and run terraform apply

Deployment will focus on libvirt-kvm. ceph-open-terrarium will use https://github.com/dmacvicar/terraform-provider-libvirt for deploying via terraform and cloudinit.

( Due to the modular nature of terraform, we might add terraform for cloud or other providers but for the first releases is out of scope.)

Config Management:

The saltstack way:

Follow instruction here: https://github.com/MalloZup/ceph-open-terrarium/tree/master/salt

The ansible way:

Once you have the IPs adress of the virtual hosts, you can use ansible. For ansible, have a look at upstream doc https://github.com/ceph/ceph-ansible

Opensource distros avaible

You can use following OS-images. Note: We are providing the OS-images, feel free to fix/expand the terraform files and relative modules.

Requirements: For adding an OS on the table we need a cloud-image avaible upstream.
