Dumb-init vs kubeadm-aws: 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, kubeadm-aws is detailed as "Low-cost Kubernetes clusters on Amazon Web Services". Bash and Terraform code which provisions affordable single master Kubernetes cluster on AWS. You can run a 1 master, 1 worker cluster for somewhere around $6 a month.
Dumb-init and kubeadm-aws can be primarily classified as "Container" tools.
Dumb-init and kubeadm-aws are both open source tools. Dumb-init with 3.84K GitHub stars and 212 forks on GitHub appears to be more popular than kubeadm-aws with 893 GitHub stars and 49 GitHub forks.
