Docker Orchestration and Microservices, Second Edition

Video Description

2+ Hours of Video Instruction

Docker Orchestration and Microservices LiveLessons, Second Edition, provides developers with key insights and best practices for how to develop and orchestrate containerized microservices.

Overview

In this video training, Charles D. Crawford starts by introducing some of the motivations behind microservices and how to properly containerize web applications using Docker. He then does a quick overview of how Docker registries can help to store artifacts from your built images. Following this, he walks you through Docker's latest tools: docker-compose, docker-machine, and docker-swarm. Specifically, Charlie covers how to use these tools to aid in both developing and deploying to a wide variety of system and container configurations. He then turns to Kubernetes, the popular container orchestration system created by Google. After watching this video, developers will have a strong understanding of modern containerized applications and microservices and will understand how these systems can benefit them.

About the Instructor

Charles David Crawford has more than ten years of software experience and five years of experience in software education. He is currently a lead instructor at Code Fellows, where he teaches full-stack web programming. He is also an active software and writing consultant and the director of marketing for Hack The People, a distributed nonprofit organization focused on fostering mentor-mentee relationships in software development. Additionally, Charlie is an active blog contributor at The New Stack, a site featuring news about and analysis of an ever-changing software development ecosystem. Prior to this, Charlie was a developer evangelist for Shippable, a SaaS that leverages Docker to provide continuous integration services. He was also a software engineer at Amazon Web Services on the Elastic Beanstalk team, where he worked on things such as the Elastic Beanstalk Ruby container, Nodejs container, and the Docker container.

Lesson Descriptions

Lesson 1: Thinking in Terms of Microservices

Lesson 1 covers the basics of what a microservice is, what problems it solves, and new challenges microservices bring. Also discussed is how Docker fits into microservices and how it can be a great help in developing microservice-based systems.

Lesson 2: Dockerizing Your Microservices

Lesson 2 looks at creating a basic microservice using Node.js. Next, this lesson covers how to create a Docker image containing the microservice and its dependencies.

Lesson 3: Using Registries to Store and Distribute Docker

Lesson 3 looks at using the Docker Hub service as a repository to store your custom docker images. Additionally covered is how to trigger automatic rebuilds of Docker images upon a code push to Github.

Lesson 4: Deploying Single Instance Single Container Apps with Docker Machine

Lesson 4 covers doing basic dockerized app deployments using Docker Machine. This sets the foundation for work in future lessons with Docker Compose and Docker swarm.

Lesson 5: Local Development of Microservices-Based Apps with Docker Compose

Lesson 5 explores how Docker is not only useful in a production environment, but a development one as well. One of the largest challenges of microservices is the more complex setup required for a development environment; however, Docker Compose makes local development easier than ever.

Lesson 6: Deploying Single Instance Multi-Container Apps with Docker Compose and Docker Machine

Lesson 6 is about extending Docker Compose beyond development environments to do multi-container apps on a single instance, quickly and easily.

Lesson 7: Multi­Instance Multi-Container Applications with Docker Swarm, Stack, and Compose

Lesson 7 is where we take our first look at complex multi-instance and multi-container deployments. Docker Swarm is built on the Docker API, so a lot of knowledge carries over from vanilla Docker, but there are still additional swarm constructs to learn, such as the master and slave node systems.

Lesson 8: Advanced Docker Swarm Configuration

Lesson 8 takes a deeper look into Docker Swarm and teaches you about advanced configuration options such as container affinities.

Lesson 9: Container Orchestration with Kubernetes

Lesson 9 looks at Kubernetes, which takes a different approach to orchestration than Swarm. Kubernetes brings in many new concepts such as pods, replication controllers, services, and more.
