Introduction to Kubernetes

Kubernetes, abbreviated as K8s, is a portable, extensible, open-source platform for managing contained workloads and services. It facilitates both declarative configuration and automation. It has a huge and rapidly growing ecosystem. Its services, support, and tools are widely available.

Kubernetes keeps track of container applications that are deployed into the cloud. It also restarts old containers that are untouched for a long and shuts containers down when they are not being used. It also provisions resources like storage, CPU, and memory when needed and manages traffic.

Kubernetes is a fairly difficult topic to get hold of. Great Learning aids an easy and better way to learn and understand Kubernetes for beginners. Implementation is as follows :

• Create a cluster.
• Deploy an app.
• Explore the app.
• Expose the app publicly.
• Scale the app.
• Update the app.
• Debug the container app.

PHP guestbook deployment using Redis, MySQL, and WordPress with persistent volumes, Cassandra deployment using stateful sets are a few examples of Kubernetes.

Kubernetes hosts microservice-based implementations since it is associated with it. Its associated ecosystem of tools provides capabilities needed to address key concerns of any microservice architecture.
