Centurion vs dockersh: What are the differences?

Centurion: A mass deployment tool for Docker fleets. A deployment tool for Docker, made by New Relic. Takes containers from a Docker registry and runs them on a fleet of hosts with the correct environment variables, host volume mappings, and port mappings. Supports rolling deployments out of the box, and makes it easy to ship applications to Docker servers. New Relic is using it to run their production infrastructure; dockersh: A shell which places users into individual docker containers. dockersh is designed to be used as a login shell on machines with multiple interactive users. When a user invokes dockersh, it will bring up a Docker container (if not already running), and then spawn a new interactive shell in the container's namespace.

Centurion and dockersh can be categorized as "Container" tools.

Centurion and dockersh are both open source tools. It seems that Centurion with 1.72K GitHub stars and 111 forks on GitHub has more adoption than dockersh with 1.28K GitHub stars and 76 GitHub forks.
