For DevOps engineers, keeping up to date with all the tools surrounding new technologies is more important than ever. Two essential tools today are Kubernetes<\/strong> and Docker<\/strong>, both of which may seem the same at first glance, both allow you to do similar things like running containers, however both work on different layers of the Cloud infrastructure. In this blog post, we will try to clarify both terms.<\/span><\/p>\n

What is a container?<\/b><\/h2>\n

Let’s start with a brief definition of what exactly a container is. Containers are a form of operating system virtualisation. A single container can be used to run anything from a small microservice or software process to a larger application.<\/span><\/p>\n

A container is like a compact box that contains all the dependencies of an application in one place. This not only allows an application to run quickly on a system, but also makes it portable, easy to transfer from one environment to another.<\/span><\/p>\n

Unlike virtual machines, containers only provide virtualization for the operating system layer and necessary dependencies, making them lighter and more portable, with a significantly lower system load. They can be easily transferred from one environment to another and operate consistently at all times by containing everything necessary for the application to function.<\/span><\/p>\n

What is Docker?<\/b><\/h2>\n

Docker<\/strong> is an open source containerisation platform launched by Docker Inc. in 2013, i.e. Docker<\/strong> is a technology used to create and run software containers. In essence Docker<\/strong> is a system that allows to build, transfer, deploy and run containers with the applications inside in a very simple and reliable way, guaranteeing a scalable deployment in an efficient way regardless of the host operating system.<\/span><\/p>\n

Docker<\/strong> streamlines the creation of containers with tools such as dockerfiles, and streamlines the code-like definition of containerised applications through docker-compose. These tools are used to create a development lifecycle, from defining what goes inside a container, to establishing its environment and access to resources. <\/span>It also helps developers move workloads from their local environment, to testing to production, eliminating inconsistencies and dependencies between environments. As the container being deployed will be the same as the one in which it was developed, the environment will have the same predictable outcome.<\/span><\/p>\n

\"Docker<\/p>\n

What is Kubernetes?<\/b><\/h2>\n

Kubernetes<\/strong> (also known as k8s<\/strong>) is a container platform orchestrator, like Docker<\/strong>. To be more precise, Kubernetes is a set of open source tools for building a scalable, fault-tolerant platform designed to automate and centrally manage containerised applications. Learn more in detail about this tool in our post What is Kubernetes?<\/a> \ud83d\udc48<\/span><\/p>\n

So how are Docker and Kubernetes similar or different?<\/b><\/h2>\n

As we can understand from the above, Docker<\/strong> and Kubernetes<\/strong> are related technologies, but they cannot be directly compared with each other. In fact, the two tools complement each other and help build cloud-native or microservices architectures. In other words, Kubernetes<\/strong> builds on top of Docker<\/strong>, using it as an engine to run containers, but it takes care of exactly how these containers are run: configuration, replication, access to system resources, or network communication. It takes care of generating these configurations and communicating them to Docker<\/strong> so that it can apply them. <\/span><\/p>\n

What is the difference between Docker<\/strong> and Kubernetes<\/strong>? Kubernetes<\/strong> is meant to run on a cluster, whereas Docker<\/strong> runs on a single node by default, with no replication management or container health maintenance, just running a container as declared. So the fundamental difference between Docker<\/strong> and Kubernetes<\/strong> is that Docker<\/strong> is a containerisation platform, meaning that it handles container creation, whereas Kubernetes<\/strong> is a container orchestration platform.<\/span><\/p>\n

Therefore, the comparison between Kubernetes<\/strong> and Docker<\/strong> is not as simple as creating a list of pros and cons or feature by feature. However, there is a Kubernetes<\/strong>-like orchestration technology developed by Docker Inc. called Docker Swarm<\/strong>, which provides us with Kubernetes<\/strong>-like elements such as replication management or load balancing between containers.<\/span><\/p>\n

Conclusion<\/b><\/h2>\n

In summary, Docker<\/strong> provides an open standard for packaging and distributing containerised applications and is sufficient to address simple use cases and Kubernetes<\/strong> leverages a broad ecosystem of tools along with continuous integration\/continuous deployment (CI\/CD) and other DevOps practices to orchestrate large sets of containers from development to production environments.<\/span><\/p>\n
