Kubernetes

Kubernetes, also called “kube,” is an open source platform used to automate Linux container operations. It’s beneficial because it helps to eliminate some of the manual processes involved in the deployment and scaling of containerized applications.

Put simply, Kubernetes allows you to cluster together groups of hosts and manage the clusters effectively. The clusters can span hosts across hybrid, private and public clouds.

While getting started with Kubernetes may seem intimidating at first, you can use the information here to get started with this technology.

The Development of Kubernetes

Originally designed by Google engineers, Kubernetes was one of the earliest contributors to the Linux container technology. It has been a source of public discussion how everything at Google actually runs in containers – this is the technology powering Google’s cloud services.

Why Use Kubernetes?

The main advantage offered by Kubernetes is that you have a platform for scheduling and running containers on clusters of virtual or physical machines. After all, if Google uses it, there has to be some merit to the technology, right?

Some of the specific things you can do with Kubernetes include:

  • Mount and add storage for running stateful apps

  • Orchestrate containers across several hosts

  • Manage services that guarantees the applications deployed are always running the way you deployed them

  • Use hardware better for maximizing resources needed to run various enterprise apps

  • Self-heal and health check apps without autoscaling, autoreplication, auto restart or autoplacement

  • Scale various containerized applications and their resources on the go

Keep in mind, Kubernetes relies on other projects to provide the orchestrated services. When you implement the use of other open source projects, you will be able to finally realize the power offered by Kubernetes.

Getting Started with Kubernetes

If you want to begin using Kubernetes, one of the first things you need to do is get to know the common terminology. Some of the terms used include:

Kubernetes

  • Pods. A group of one or more containers that share storage and a network.

  • Nodes. Represents the worker machine in the cluster.

  • Master Node. Where the master components are installed.

  • Deployments: This is a set state for your pods.

Once you know the terminology, you can move on to other important parts of Kubernetes use.

To successfully harness the power of Kubernetes, you need a Docker. There are options to download online. At this point, you can utilize a tutorial to create your first cluster and to deploy an app. Depending on what you want to do will take you to your next steps.

It’s important to understand that Kubernetes is a full-fledged deployment, scaling and scheduling manager. It can decide on all the details of how to properly deploy a specific app on the cluster you create. One of the most appealing parts of working with Kubernetes is the fast that it is a fast and easy process. Also, you don’t have to supply many details to use it successfully. As with any new skill, it will take some time for you to become a Kubernetes master.
