Container Orchestration

These days almost every software developer has come to know about Docker. In fact, most people use it in their software development journey. Almost everyone knows about Docker—how to write a Dockerfile, how to write a Docker Compose file, how to push or pull images, how to reduce image size, how to configure Docker networks, persistent volumes, Docker commands, etc.

Shipping applications in Docker is easy — but shipping lightweight, secure, and optimized images is where the real DevOps skills shine. That’s exactly what Multi-Stage Dockerfiles help you achieve.

Kubernetes is a system that helps run and manage container based applications at a large scale. The diagram of the cluster shows several important parts working together. Even though the image may look complex, the design follows a clear and simple idea. A Kubernetes cluster is divided into the control plane and the worker nodes. The control plane makes decisions while the nodes run the actual applications. Once this relationship becomes clear, the entire architecture becomes easy to understand.
