This blog post demonstrates how you can use the Operator Lifecycle Manager to deploy a Kubernetes Operator to your cluster. Then, you will use the Operator to spin up an Elastic Cloud on Kubernetes (ECK) cluster.
An operator is a software extension that uses custom resources (extension of the Kubernetes API) to manage complex applications on behalf of users.
The artifacts that come with an operator are:
The complexity encapsulated within an Operator can vary, as shown in the below diagram:

Following the second video about Docker basics, in this video, I explain Docker architecture and explain the different building blocks of the docker engine; docker client, API, Docker Daemon. I also explain what a docker registry is and I finish the video with a demo explaining and illustrating how to use Docker hub.
Docker and Kubernetes are two orchestration tools that very popular. Many people have trouble picking one. In this video on Docker vs Kubernetes, we will be comparing these two tools end to end and see which one will suit your needs better.
Basically, both Kubernetes and Docker Swarm both are the container orchestration tool. The rise in interest to containers has in turn brought in higher demands for their deployment and management. Both Kubernetes and Docker Swarm are important tools that are used to deploy containers inside a cluster. So the question arises here is which one to use? So lets discuss one by one and see the the differances between them.
