Dumb-init vs Helios: What are the differences?
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; Helios: Docker container orchestration platform, by Spotify. Helios is a Docker orchestration platform for deploying and managing containers across an entire fleet of servers. Helios provides a HTTP API as well as a command-line client to interact with servers running your containers.
Dumb-init and Helios can be categorized as "Container" tools.
Dumb-init and Helios are both open source tools. It seems that Dumb-init with 3.83K GitHub stars and 212 forks on GitHub has more adoption than Helios with 2K GitHub stars and 229 GitHub forks.
