Continues development, integration and deployment

Application-centric management

Containerized infrastructure

Auto-scalable infrastructure

Environment consistency across development testing and production

Higher density of resource utilization

Loosely coupled infrastructure, where each component can act as a separate unit

Predictable infrastructure which is going to be created

container-centric infrastructure

Kubernetes comes with a capability of automating deployment, scaling of application, and operations of application containers across clusters. It is capable of creating container centric infrastructure.

One of the key components of Kubernetes is, it can run application on clusters of physical and virtual machine infrastructure. It also has the capability to run applications on cloud. It helps in moving from host-centric infrastructure to container-centric infrastructure.

Learn kubernetes

In this chapter, we will discuss the basic architecture of Kubernetes, including Cluster Architecture, Master Machine components, Node components, and Master Node structure.

It is important to set up the Virtual Datacenter (vDC) before setting up Kubernetes. This can be considered as a set of machines where they can communicate with each other via the network. For hands-on approach, you can set up vDC on PROFITBRICKS if you do not have a physical or cloud infrastructure set up.

Kubernetes (Docker) images are the key building blocks of Containerized Infrastructure. As of now, we are only supporting Kubernetes to support Docker images. Each container in a pod has its Docker image running inside it.

The main function of a job is to create one or more pod and tracks about the success of pods. They ensure that the specified number of pods are completed successfully. When a specified number of successful run of pods is completed, then the job is considered complete.

Labels are key-value pairs which are attached to pods, replication controller and services. They are used as identifying attributes for objects such as pods and replication controller. They can be added to an object at creation time and can be added or modified at the run time.

Namespace provides an additional qualification to a resource name. This is helpful when multiple teams are using the same cluster and there is a potential of name collision. It can be as a virtual wall between multiple clusters.

what people say

"Kubernetes advocate points to software's roots inside Google, its self-healing features and its container cluster know-how."
"Kubernetes is meant to simplify things and this article is meant to simplify Kubernetes for you! Kubernetes is a powerful open-source system that was developed by Google."
"Kubernetes: A Journey Towards Containerization Though Docker has become the de facto champ of containers, Kubernetes and its clusters offer an alternative choice."
"New research on Kubernetes security suggests that hundreds of installations worldwide have been hijacked for cryptomining — most due to a combination of recent reported vulnerabilities and Kubernetes APIs exposed to the Internet with no authentication required for access."
