DebOps

DebOps is an open-source infrastructure-as-code project that provides a comprehensive set of Ansible roles and playbooks. It is designed to manage data center environments specifically running on Debian or Ubuntu hosts. The software allows administrators to configure servers in a controlled manner using Ansible inventory groups, ensuring that system states remain consistent across the entire infrastructure.

Deployment occurs via an Ansible Controller host, which can be set up using a Docker container, a Vagrant virtual machine, or by installing the DebOps Python package. Users manage their infrastructure by creating dedicated project directories and running playbooks against hosts connected via SSH. This approach allows for the management of a single host or the coordination of complex, multi-node clusters.

Key features

• General-purpose Ansible roles for Debian and Ubuntu hosts
• Support for various SQL and NoSQL databases
• Configuration for multiple web servers and programming languages
• Deployment of virtualization environments using KVM, libvirt, Docker, or LXC
• High customization through Ansible inventory variables
• Management of services on single hosts or distributed clusters
• Integration with Ansible Galaxy as a collection
• Project initialization tools via the debops project init command

The architecture relies on Ansible to push configurations to remote nodes. It emphasizes security by disabling password authentication in favor of SSH keys, which is the recommended method for connecting to managed hosts. The system is designed for sysadmins who need to maintain consistent configurations across multiple environments while keeping the core playbook code shared. It supports a wide array of specialized data center applications and provides a structured way to scale from a single server to a full cluster. Because the firewall is configured by the software, out-of-band console access is recommended for initial troubleshooting.

DebOps serves as a comprehensive toolkit for the automated provisioning and management of Debian-based server infrastructure.
