Kubernetes vs Docker Swarm and Container Orchestration War निजी वीडियो

“Kubernetes vs. Docker” is a phrase that you hear more and more these days as Kubernetes becomes ever more popular as a container orchestration solution.

However, “Kubernetes vs. Docker” is also a somewhat misleading phrase. When you break it down, these words don’t mean what many people intend them to mean, because Docker and Kubernetes aren’t direct competitors. Docker is a containerization platform, and Kubernetes is a container orchestrator for container platforms like Docker.

It is easy to get lost in the details of Kubernetes, but at the end of the day, what Kubernetes is doing is pretty simple. Cheryl Hung of the CNCF describes Kubernetes as a control loop. Declare how you want your system to look (3 copies of container image a and 2 copies of container image b) and Kubernetes makes that happen. Kubernetes compares the desired state to the actual state, and if they aren’t the same, it takes steps to correct it.

Docker is currently the most popular container platform. Docker appeared on the market at the right time, and was open source from the beginning, which likely led to its current market domination. 30% of enterprises currently use Docker in their AWS environment and that number continues to grow.

A Docker Swarm is a group of either physical or virtual machines that are running the Docker application and that have been configured to join together in a cluster. Once a group of machines have been clustered together, you can still run the Docker commands that you're used to, but they will now be carried out by the machines in your cluster. The activities of the cluster are controlled by a swarm manager, and machines that have joined the cluster are referred to as nodes.
