AlviStack

Gitlab pipeline status GitHub tag GitHub license Ansible Collection

Ansible collection for deploying Ceph.

This Ansible collection provides Ansible playbooks and roles for the deployment and configuration of an Ceph environment.

Requirements

This collection require Ansible community package 4.10 or higher.

This collection was designed for:

  • Ubuntu 20.04, 22.04, 24.04
  • AlmaLinux 8, 9
  • openSUSE Leap 15.5, 15.6, Tumbleweed
  • Debian 11, 12, Testing
  • Fedora 39, 40, Rawhide
  • CentOS 7, 8 Stream, 9 Stream
  • RHEL 7, 8, 9

Quick Start

Bootstrap Ansible and Roles

Start by cloning the repository, checkout the corresponding branch, and init with git submodule, then install Ansible (see https://software.opensuse.org/download/package?package=ansible&project=home%3Aalvistack):

# GIT checkout development branch
mkdir -p /opt/ansible-collection-ceph
cd /opt/ansible-collection-ceph
git init
git remote add upstream https://github.com/alvistack/ansible-collection-ceph.git
git fetch --all --prune
git checkout upstream/develop -- .
git submodule sync --recursive
git submodule update --init --recursive

# Bootstrap Ansible
echo 'deb http://downloadcontent.opensuse.org/repositories/home:/alvistack/xUbuntu_24.04/ /' | tee /etc/apt/sources.list.d/home:alvistack.list
curl -fsSL https://downloadcontent.opensuse.org/repositories/home:alvistack/xUbuntu_24.04/Release.key | gpg --dearmor | tee /etc/apt/trusted.gpg.d/home_alvistack.gpg > /dev/null
apt update
apt install ansible

# Confirm the version of Ansible
ansible --version

AIO

All-in-one (AIO) build is a great way to perform an Ceph build for:

  • A development environment
  • An overview of how all the Ceph services fit together
  • A simple lab deployment

Simply execule our default Molecule test case and it will deploy all default components into your localhost:

# Run Molecule test case
molecule test -s default

# Confirm the version and status of Ceph
ceph --version
ceph --status
ceph health detail

Production

In order to avoid Single Point of Failure, at least 3 instances for Ceph is recommended.

This deployment will setup the follow components:

  • Ceph
    • Ceph Monitor Daemon
    • Ceph Manager Daemon
    • Ceph Object Storage Daemon
    • Ceph Metadata Server
    • Ceph Object Gateway

Start by copying the default inventory for customization:

# Copy default inventory
mkdir -p /etc/ansible
rsync -av /opt/ansible-collection-ceph/inventory/default/ /etc/ansible

You should update the following files as per your production environment:

  • /etc/ansible/hosts
    • Update with your inventory hostnames and IPs
  • /etc/ansible/group_vars/all/*.yml
    • Update *_release and *_version if you hope to pin the deployment into any legacy supported version

Once update now run the playbooks:

# Run playbooks
cd /opt/ansible-collection-ceph
ansible-playbook playbooks/converge.yml

# Confirm the version and status of Ceph
ceph --version
ceph --status
ceph health detail

Molecule

You could also run our Molecule test cases if you have Vagrant and Libvirt installed, e.g.

# Run Molecule on Ubuntu 24.04
molecule converge -s ubuntu-24.04

Please refer to .gitlab-ci.yml for more information on running Molecule.
