It’s the secret sauce that has made Docker internet-famous with developers. This opinionated approach to containers keeps the CLI friendly and easy to use for beginners. It can do this in a single, short command. Each container gets its own networking and resource limits and can’t see anything else on the host operating system. Easy app runningĭocker runs each container in an isolated file system. The container image standard is a major improvement compared to previous packaging systems (like apt, yum, msi, npm, maven, etc.) that don’t contain application dependencies. This is now considered the modern way to package server apps. The app tarball(s) and metadata are known together as a container image. Docker ensures these tarballs are identical on every machine they run on using cryptographic hashing.

Easy app packagingĭocker takes your application and all of its software dependencies – minus the OS kernel and hardware drivers – and bundles them in a set of tarballs (similar to zip files). Docker’s three key innovationsĭocker invented three processes for containerized applications that we previously couldn’t do easily in a single command-line and server daemon: 1. Millions of people use it every month, and I recommend it. Docker Desktop is the easiest way to run Docker and Kubernetes on your local machine for dev and testing server apps. Note that Docker also makes Docker Desktop, a bundle of products for Windows and Mac. This is what people are usually talking about when they say “Docker,” and what I’ll refer to by default in this article. In this post, we’ll focus on the original project, now called Docker Engine. They now make a line of products with Docker in the name. Soon after Docker’s release, the founders scrapped Dotcloud and created Docker Inc. What’s Docker Engine got to do with Docker? The team that created Docker took complex tools and wrapped them in a command-line interface (CLI) that mere mortals could understand.

Yet, there wasn’t an easy-to-use tool that focused on the full application lifecycle until Docker. The concept of containerized applications – using containers to isolate many apps from each other on a single server – has existed for decades. The more I understood about its features, the more I wanted to use Docker everywhere. When it hit 1.0 in 2014, I gave it a try. In 2013, Solomon Hykes, CEO of Dotcloud, announced the Docker open source project. What about serverless, and how are containers related?.Does everyone need both Docker and Kubernetes?.Is “Docker Engine” different from Docker?.What are these tools, and why are they important?.In this post, I’ll address questions like the following: There’s a lot to unpack in those statements.

It knows how to manage containers across many operating system hosts, which in turn, run their own container runtime. Kubernetes (K8s) is an open-source “container orchestration platform” (AKA orchestrator).Docker Engine is a “container runtime.” It knows how to run and manage containers on a single operating system host.
Versus isn’t the right question, though, because using these tools isn’t an either-or equation. Like me, the tech world is enamored with container tooling, of which Docker and Kubernetes are the two top brands. As a Docker Captain and a Udemy instructor to 300,000 Docker and Kubernetes students, the Kubernetes vs.
