r/docker is a subreddit with 323k members. The most common kinds of discussions are solution requests and ideas, and the community frequently discusses docker, docker container, container, docker network, and database, and they frequently recommend/review monitoring tool, hosting, and vpn solution.
Docker is an open-source project to easily create lightweight, portable, self-sufficient containers from any application. The same container that a developer builds and tests on a laptop can run at scale, in production, on VMs, bare metal, OpenStack clusters, public clouds and more.
