How does docker and kubernetes work together software#

You can think of this as a snapshot of your application, ready to be brought to life at any time. Dockerfiles define a build process, which, when fed to the ‘docker build’ command, will produce an immutable docker image. With Docker, you create a special file called a Dockerfile. It’s an open source collection of tools that help you “Build, Ship, and Run any App, Anywhere”.

This all sounds really nice, but how do you actually build a container? Build and Deploy Containers with Dockerĭocker helps you create and deploy software within containers. And while some may not yet be building microservices, traditional monoliths can be containerized and reap some of the aforementioned benefits. While the industry pushes towards building microservice architectures, containers help facilitate quick elasticity and separate of concerns. The above characteristics make containers an awesome tool and essential building block in modern cloud architecture. a virtual machine will improve startup time significantly. For this reason, bundling your application in a container vs. You can think of running a container like running a virtual machine, without the overhead of spinning up an entire operating system. All of your application’s code, libraries, and dependencies are packed together in the container as an immutable artifact. There are no unexpected errors when you move it to a new machine, or between environments. What makes them special is that when you run a container, you know exactly how it will run - it’s predictable, repeatable and immutable. Containers - A Quick IntroĪt their core, containers are a way of packaging software. Let’s take a look to see how they both fit into the world of linux containers, and how you can use them when architecting your own applications. Understanding both Docker and Kubernetes is essential if you want to build and run a modern cloud infrastructure. If you look a little closer, you’ll find that the technologies operate at different layers of the stack, and can event be used together.
