Docker for Devs and Security Professionals

Docker, and the containers it makes possible, has revolutionized the software industry and in a few years, their popularity as a tool and platform has skyrocketed and Docker containers have become a massively popular technology. In this blog post, I will walk you through the basic components, architecture, and basic commands of docker.

The Docker technology uses the Linux kernel and features of the kernel, like Cgroups and namespaces, to segregate processes so they can run independently.

Container images become containers at runtime and in the case of Docker containers — images become containers when they run on Docker Engine.

It aims to be an alternative to the official Docker CLI when it is needed to repeatedly execute commands on existing containers and images, and as a tool to monitor Docker containers from a terminal.
