Dumb-init vs DevSpace Cloud: What are the differences?
What is 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.
What is DevSpace Cloud? Secure Multi-Tenancy and On-Demand Namespace Provisioning for Kubernetes. It lets IT teams create an internal Kubernetes offering that enables their developer teams to create isolated namespaces in shared development clusters. The goal is to allow engineers to get access to Kubernetes in a self-service fashion. It restricts developers to their own namespaces allowing secure cluster sharing while handling all the admistrative overhead such as the management of the kube-context on an engineers machine.
Dumb-init and DevSpace Cloud can be categorized as "Container" tools.
