Docker Compose vs Dumb-init: What are the differences?
Developers describe Docker Compose as "Define and run multi-container applications with Docker". With Compose, you define a multi-container application in a single file, then spin your application up in a single command which does everything that needs to be done to get it running. On the other hand, Dumb-init is detailed as "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.
Docker Compose and Dumb-init belong to "Container Tools" category of the tech stack.
Docker Compose and Dumb-init are both open source tools. It seems that Docker Compose with 16.6K GitHub stars and 2.56K forks on GitHub has more adoption than Dumb-init with 3.83K GitHub stars and 212 GitHub forks.
