Centurion is a subscription-based deployment tool designed for Docker that facilitates the management of containerized applications across a fleet of hosts. It streamlines the deployment process by taking containers from a Docker registry and running them with the necessary environment variables, volume mappings, and port configurations. The tool supports rolling deployments, making it easy to update applications on Docker servers without downtime. Designed for a variety of users, from small businesses to enterprises, Centurion is built with community input and has an active maintainer team.

The deployment process in Centurion is divided into two main stages: the build process, which ships containers to the registry, and the deployment process, where Centurion transfers these containers from the registry to the Docker fleet. It integrates seamlessly with Docker's command-line tools, ensuring compatibility with various registries. With online support and comprehensive documentation, Centurion also offers an API for further integration with services like AlertOps and WebLOAD, enhancing its functionality in IT environments.
