Kubernetes commands that every developer must know ☸
Introduction:
Kubernetes is the most hyped and well-paid skill of 2023. As a developer, you must have an idea about Kubernetes.
Kubernetes is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications. It provides a framework for managing distributed systems, allowing developers to focus on writing and shipping code, rather than managing infrastructure. Kubernetes simplifies the process of deploying and scaling applications, allowing developers to easily manage and monitor their applications across multiple environments. By using Kubernetes, developers can deploy applications faster, improve scalability, increase reliability, and reduce downtime. In short, Kubernetes is a critical tool for modern software development and deployment, helping developers to build and deploy applications faster and more efficiently.
The blog post will cover basic commands such as kubectl create, get, describe, delete, and apply. It will also cover advanced commands including kubectl logs, exec, port-forward, rollout, and scale. The post will explain how these commands can be used for troubleshooting Kubernetes issues, such as using kubectl describe to get detailed information about resources and using kubectl logs to view container logs.
