Learning Docker - Second Edition by Pethuru Raj

Key FeaturesThis up-to-date edition shows how to leverage Dockers features to deploy your existing applicationsLearn how to package your applications with Docker and build, ship, and scale your containersExplore real-world examples of securing and managing Docker containersBook DescriptionDocker is an open source containerization engine that offers a simple and faster way for developing and running software. Docker containers wrap software in a complete filesystem that contains everything it needs to run, enabling any application to be run anywhere – this flexibily and portabily means that you can run apps in the cloud, on virtual machines, or on dedicated servers.This book will give you a tour of the new features of Docker and help you get started with Docker by building and deploying a simple application. It will walk you through the commands required to manage Docker images and containers. Youll be shown how to download new images, run containers, list the containers running on the Docker host, and kill them.Youll learn how to leverage Dockers volumes feature to share data between the Docker host and its containers – this data management feature is also useful for persistent data. This book also covers how to orchestrate containers using Docker compose, debug containers, and secure containers using the AppArmor and SELinux security modules.What you will learnDevelop containerized applications using the Docker version 17.03Build Docker images from containers and launch themDevelop Docker images and containers leveraging DockerfilesUse Docker volumes to share dataGet to know how data is shared between containersUnderstand Docker Jenkins integrationGain the power of container orchestrationFamiliarize yourself with the frequently used commands such as docker exec, docker ps, docker top, and docker statsAbout the AuthorJeeva S.
