Kubernetes and Docker are open source platforms which are designed to run multiple containers as a single machine. They both work on OS level virtualization which is faster than the traditional virtual machine. According to Byteplant, enterprises can integrate both platforms with the email validator API to help manage emails in a secure manner in real time. When comparing Kubernetes and Docker, you will have to know how they work and how they relate to each other. In the real sense, it is the Kubernetes and Docker Swarm, Docker’s native container management tool, you should be comparing with.
How the two relate
Docker is a platform on which containers run while Docker Swarm is the container management tool similar to Kubernetes. Through the Swarm, Kubernetes, a Google product, can relate well to the functions played by the former. Both of this container orchestration solutions play a vital role that addresses the limitations of virtual machines. They are able to run containers in an efficient way thereby taking care of the heavy workloads through scalability. They are open sourced which means that they have an interactive community in which you can learn how to make the best use of either of the tools.
The setup and installation
They both run on Linux but differ when it comes to setup and installation. In the case of Docker Swarm, it has become popular due to its simplicity when it comes to setting it up. As soon as the swarm is set in a particular node within the platform, using the command line interface (CLI) or the Docker API, you are good to go. Other nodes will be joined into that swarm with the help of the CLI to complete the setup of coordinating containerized workloads.
Kubernetes, on the other hand, is complex when it comes to setting it up. For each OS you will use a different setup. It is thus difficult especially when you want to set it up on multiple nodes. It will require a lot of work in planning, as you will need to perform some manual integrations on the tool to make it run. However, such complexities can be made lighter by using the online resources which can come in handy to help you get by.
Superiority in functionality
Kubernetes boasts of supporting multiple versions of monitoring and logging. This takes place when the services it provides are deployed. However, Docker is dependent on third-party applications in monitoring. In the ability to spin containers, Kubernetes used to be the powerhouse but with the recent updates on Docker, this has changed. The two can now accommodate about 1000 nodes and 30,000 containers. Due to the complexities of Kubernetes in setting up and running containers, Docker is able to spin containers faster than the former. Even with all that, Kubernetes can be deployed on Docker engine to help with container orchestration on Kubernetes.
Kubernetes vs Docker can vary depending on the enterprise needs as the two tools closely contest in terms of functionality. As such, it is a case of what you want to achieve based on the needs of your business and objectives you want to attain.
