CPU Management in Docker 1.13
Resource management for containers is a huge requirement for production users. Being able to run multiple containers on a single host and ensure that one container does not starve the others in terms of cpu, memory, io, or networking in an efficient way is why I like working with containers.

Docker containerd integration
In an effort to make Docker Engine smaller, better, faster, stronger, we looked for components of the current engine that we can break out into separate projects and improve along the way. One of those components is the Docker runtime for managing containers. With standalone runtimes like runc, we need a clean integration point for adding…
