Centurion vs Dumb-init: 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; Dumb-init: A minimal init system for Linux containers, by Yelp. dumb-init runs as PID 1, acting like a simple init system. It launches a single process and then proxies all received signals to a session rooted at that child process. Since your actual process is no longer PID 1, when it receives signals from dumb-init, the default signal handlers will be applied, and your process will behave as you would expect. If your process dies, dumb-init will also die, taking care to clean up any other processes that might still remain.
Centurion and Dumb-init belong to "Container Tools" category of the tech stack.
Centurion and Dumb-init are both open source tools. It seems that Dumb-init with 3.83K GitHub stars and 212 forks on GitHub has more adoption than Centurion with 1.72K GitHub stars and 111 GitHub forks.
