Maintaining the Docker environment is always a nightmare for developers and DevOps, and if done manually, it’s very time-consuming. It’s also not easy to deploy an application across environments while retaining details of the system. However, Docker solves this by introducing agile and portable Containers. These Containers can run anywhere, meaning developers and DevOps don't need to worry about the environment. It’s easier to work with Docker and it's built with security in mind.

Docker is a tool that is designed to benefit both developers and system administrators. For developers, it means they can develop applications without worrying about the system it will be running on. For system administrators, it gives them flexibility and reduces the number of systems required.

This comprehensive 3-in-1 course is a step-by-step guide which will walk you through the features and use of Docker, from Docker software installation to sharing data between containers. The course will start by giving you a basic understanding of Docker and building an online shopping application. Then, you'll use the Docker CLI tool to develop, share and deploy images also setting up the environment. As you have developed an application, you'll learn to create an application file with Docker Compose and deploy it in the cloud. Finally, you'll work with Docker repository and deploy the application in Heroku. Also, you'll learn to monitor the application.

By the end of the course, you’ll master the art of containerizing your applications using Docker, enhancing the software development process!

Contents and Overview

This training program includes 3 complete courses, carefully chosen to give you the most comprehensive training possible.

The first course, Getting Started with Docker, covers transforming the way you deploy your applications! This video course begins by introducing the basic Docker commands in Docker 1.12. You will quickly learn how to write a Docker file, build an image from it, and then launch a container from that image. You will also get your hands dirty with common Docker tasks such as pushing images to remote repositories and using port mappings and the image caching layer during builds. Finally, you will explore how to run Docker Services and learn how it can be used to run a group of related Docker containers. We’ll also discuss some more advanced topics such as sharing data between containers.

The second course, Hands-On Docker for Microservices, covers building a cloud-native microservice application with Spring Boot 2 and use Docker to orchestrate the Containers. This course starts by giving you a basic understanding of Docker. You’ll build an online shopping application, which we’ll later deploy in various environments. Once you have successfully run your first Container, you’ll be introduced to the CLI tool, which will help you to develop, deploy, and share Docker images. Next, you'll create an application file with Docker Compose deploy it on the cloud. You’ll also add services to the application by adding a service registry, performing health checks, and running the application successfully with these services. Finally, you’ll deploy the application in Heroku and will learn how to check and monitor the application.

The third course, Mastering Docker, covers mastering the art of containerizing your applications using Docker. This video will teach you to leverage advanced-level Docker. It starts by introducing how Docker works the way it does, first scripting a layer in a Docker workflow—Dockerfile. Next, you will explore compose by writing a docker-compose.yml file for a social network app, and look at top-down approaches to building network topologies for our social network’s containers. Then you will be familiarized with the swarm workflow, Kubernetes, and Google’s tool for setting up a managed cluster. You will learn how to set up Docker’s plugin infrastructure and use the customization options. By the end of this course, you will be able to successfully manage your Docker containers, with the help of the Minecraft server.

Final para, wrap up with the key outcome. As always, keep it simple and powerful.

By the end of the course, you’ll transform the way you deploy your applications by mastering the art of containerizing your applications.
