Kubernetes is an open-source container orchestration system for automating application deployment, scaling, and management. It was originally designed by Google and is now maintained by the Cloud Native Computing Foundation.
Kubernetes is a popular choice for deploying containerized applications because it provides a high level of abstraction over the underlying infrastructure, allowing operators to focus on their applications rather than on the infrastructure.
There are a number of Kubernetes operators available, each with its own advantages and disadvantages. In this article, we will take a look at some of the most popular Kubernetes operators.
