Kubernetes in Google Cloud
1 like43 views
This document provides an overview of using Kubernetes and Docker for continuous delivery. It discusses using Jenkins for continuous integration and delivery within a Kubernetes cluster. Topics covered include Docker, Kubernetes concepts like pods and deployments, managing deployments with techniques like rolling updates, canary deployments and blue/green deployments, and using Helm as a package manager for Kubernetes. The document includes hands-on examples for common Kubernetes tasks.

- 6. What is Docker? & Why use Docker? ● Docker is a software that allows us to run applications in separate environments called containers. ● Docker makes it easier to create, deploy and run applications. ● Uses Linux cgroups (control groups) to create and run multiple isolated Linux VEs on a single control host
- 8. Dockerfile A Dockerfile is a text document that contains all the commands a user could call on the command line to assemble an image.

- 68. Continuous Delivery With Jenkins In Kubernetes An open source automation server. With Jenkins, organisations can accelerate the software development process through automation. Jenkins manages and controls development lifecycle processes of all kinds, including build, document, test, package, stage, deployment, static analysis and many more.
