Clair vs Dumb-init: What are the differences?
Developers describe Clair as "Open Source Vulnerability Analysis for your Containers". Clair is a container vulnerability analysis service by CoreOS. It provides the list of vulnerabilities that threaten each container and can sends notifications whenever new vulnerabilities that affect existing containers are released. 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.
Clair and Dumb-init belong to "Container Tools" category of the tech stack.
Clair and Dumb-init are both open source tools. Clair with 5.41K GitHub stars and 696 forks on GitHub appears to be more popular than Dumb-init with 3.83K GitHub stars and 212 GitHub forks.
