## What is a Container { #what-is-a-container }

Containers (mainly Linux containers) are a very **lightweight** way to package applications including all their dependencies and necessary files while keeping them isolated from other containers (other applications or components) in the same system.

  // If a key hashes to 0x89abcdef the mask reduces it to 0x89abcdef & 0x7f == 0x6f. We'll call this

  kubeadm: added preflight check for `losetup` on Linux nodes. It's required by kubelet for keeping a block device opened. ([#129450](https://github.com/kubernetes/kubernetes/pull/129450), [@carlory](https://github.com/carlory)) [SIG Cluster Lifecycle]
