Kubernetes controller manager: The information on the current situation of the clusters is shared by the Kube-controller manager, which then retrieve this information and help in making important decisions on how to achieve the goal required.

It has a direct interaction with the clusters of Kubernetes.

Kubernetes API server: Manageable by the humans these are API servers that divulge the levers and gears of the Kubernetes.

Now, take a look at the architecture of Kubernetes: On the other hand, Pod is an amalgamation of associated Docker containers that have a coexistence. Node is the metal servers that is managed by Kubernetes along with other virtual machines. One of the two concepts is the Pod and the other one is the Node.

There are two important fundamental concepts that bear an association with Kubernetes. It is also responsible to take care of the health of these containers.Īn overview of the architecture of Kubernetes It operates Linux container operations and gather the groups in an organized manner. It is fundamentally an open-source container-orchestration for managing services that are in containers. The list of these elements includes the likes of plugins, containers, volumes, images, networks and more. Docker objects: These are basically the elements that can be created using Docker.

It has a secured connection of TLS to avoid any sort of digital or manual attacks.

The push and pull functions of the registries is done through HTTP API on the Docker registries.

It can store a large number of images, irrespective the size of the image.

It is able to store various tags for a single image.

Take a look at the functions performed by Docker registries:

Docker registries: It is a system that stores the Docker images and does their distribution as well.

This enables a Demon communicate with other Deamons and manage the objects listed under it such as networks, volumes, images and the containers as well.

Docker Daemon: This is the server that runs through the requests received on the APIs.

All a user has to do is to run the command, which transfers them to the server, taking the process further.

Docker client: It is the first and the most important route that helps the users interact with the docker and can simultaneously communicate with a number of Daemons (servers).

Take a look at the architecture of Docker:

Running on one system only, Docker client and Docker Daemon (server) can possibly work together. Look at the components of the Docker engine: It works on a client-server architecture allowing the user to develop, collect, ship an application and control its execution in a safe environment. The virtual machines can also help the run time of the Docker machines. It is because of the isolation, that several containers can run simultaneously with just one host. It runs applications in an isolated environment. What is Docker?ĭocker is a platform which enables the delivery of softwares as a service product, using OS-level virtualization, in different packages which are known as containers. These two are best when they work together in migrating the infrastructure of a business to cloud-native in containers. Docker is a containerization platform, whereas, Kubernetes is a container orchestration platform. These are two important fundamental tools required in the deployment of apps.
