Dumb-init vs DevSpace for Kubernetes: What are the differences?
Developers describe Dumb-init 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. On the other hand, DevSpace for Kubernetes is detailed as "The Fastest Developer Tool for Kubernetes". It is an open-source developer tool for Kubernetes that lets you develop and deploy cloud-native software faster. It is a client-only CLI tool that runs on your machine and works with any Kubernetes cluster. You can use it to automate image building and deployments, to develop software directly inside Kubernetes and to streamline workflows across your team as well as across dev, staging and production.
Dumb-init and DevSpace for Kubernetes can be categorized as "Container" tools.
Dumb-init is an open source tool with 4.25K GitHub stars and 240 GitHub forks. Here's a link to Dumb-init's open source repository on GitHub.
