## What it is
Centurion is a Ruby-based CLI deployment tool that ships Docker containers from a registry to a fleet of hosts with environment, volume, and port configuration. It supports rolling deployments out of the box but is now archived and unmaintained.

## Use cases
- deploy docker containers to multiple hosts
- rolling deployments for dockerized apps
- ship containers from a registry to a server fleet
- manage environment variables and port mappings across docker hosts
- automate docker fleet deployments from ci

## When to choose
- you maintain an existing Centurion-based deployment setup
- you need a simple registry-to-hosts deployer and accept unmaintained software

## When to avoid
- starting a new deployment pipeline (project is archived)
- you need bug fixes, security patches, or new features
- you want Kubernetes or modern orchestrator-based deployments
