When you use the basic run command, Docker automatically generates a container name with a string of randomly selected numbers and letters. Although Docker still supports docker run, it recommends getting use to the new syntax. Accordingly, run is now a subcommand of docker container and to use it you must type docker container run.

Master the most in-demand Kubernetes skillsĪ Cloud Guru makes it easy (and awesome) to level up your cloud career - whether you’re new to cloud or a seasoned pro. It includes lessons that will walk you through the process of installing containerd and using it in your Kubernetes cluster.

If you are interested in learning how to use containerd alongside Kubernetes, check out my new course, Introduction to Kubernetes. You can also continue to use Docker registries to store and manage your images. You can continue to use Docker to build your images, as well as to run containers locally for development purposes, or in your continuous integration (CI) stack. Other than that, nothing is really changing. Starting now, you may want to start building any new nodes so that they use a non-Docker container runtime as well. Instead, use another container runtime, such as containerd or CRI-O.īefore upgrading to a Kubernetes version removes support for Docker (which is currently estimated to release in late 2021), you will need to modify (or replace) existing Kubernetes nodes so that they use a supported container runtime other than Docker. Moving forward, you can simply eliminate Docker as a middle-man in your Kubernetes environment. If you are currently using Docker as a container runtime in your Kubernetes environment, you will need to make some changes.

Looking to get certified on K8s? Read our blueprint for the Kubernetes certification journey.Ĭontainerd and CRI-O: Docker Alternatives This means that Docker will remain a powerful contender when it comes to managing the images once they are built.Īll in all, Docker will continue to be a useful tool on your development workflows and continuous integration (CI) systems, even if you don’t need it to run your containers underneath Kubernetes in production. Kubernetes will also continue to be able to pull from Docker registries (such as Docker hub). Kubernetes can still run containers built using Docker’s Open Container Initiative (OCI) image format, meaning you can still use Dockerfiles and build your container images using Docker. Now, however, there are plenty of runtimes available that implement the CRI, and it no longer makes sense for Kubernetes to maintain special support for Docker.Īlthough Docker is not needed as a container runtime in Kubernetes, it still has a role to play in the Kubernetes ecosystem, and in your workflow.ĭocker is still going strong as a tool for developing and building container images, as well as running them locally. In the past, there weren’t as many good options for container runtimes, and Kubernetes implemented the Docker shim, an additional layer to serve as an interface between Kubernetes and Docker. This is essentially a standard way of communicating between Kubernetes and the container runtime, and any runtime that supports this standard automatically works with Kubernetes.ĭocker does not implement the Container Runtime Interface (CRI). Kubernetes works with all container runtimes that implement a standard known as the Container Runtime Interface (CRI). Kubernetes has supported using Docker a container runtime up to this point, so why are they choosing to stop supporting it? You will still be able to use Docker in other ways that are relevant to Kubernetes (more on that in a moment), but you will not be able to use Docker as the container runtime underneath Kubernetes. However, this will no longer be an option in the future. Up to now, a fairly popular option was to use Docker as the container runtime.

You can actually choose from a variety of options when it comes to what software you want to use as your container runtime when running Kubernetes. The container runtime runs containers on a host, and Kubernetes tells the container runtime on each host what to do.
