Finally, you'll learn how to build a simple Python web application, an ASP.Net Core and SQL Server web site, a Django/PostgreSQL application, a Rails/PostgreSQL application, and a WordPress application using Docker Compose.

Docker is a set of platform as a service products used to build and share containerized apps. Docker enables applications to be separated from infrastructure, allowing for a quicker delivery. In this course, you'll learn the fundamentals of the Docker platform and container storage. You'll explore multi-container Docker applications, as well as common multi-container Docker scenarios. Next, you'll examine Docker Compose, a tool used for defining and running multi-container Docker applications. You'll explore how to setup Docker Compose, add containers to a project, and debug containers using VS Code. Lastly, you'll learn how to work with multiple Compose files, as well as how to review a multi-application strategy.

A microservice architecture is used to structure an application as a collection of loosely coupled services. Microservices are independently deployable and scalable, offer improved fault isolation, and result in smaller and faster deployments. In this course, you'll learn about the fundamentals, importance, and value of microservices. You'll learn to recognize the intersection of microservices and Docker, and the advantages of using Docker for microservices. Explore how Docker's compactness and brevity lends itself to the microservices solution, and learn how Docker and microservices work together. Lastly, you'll learn how to deploy at a Docker deployment with at least 2 microservices.

Docker is a very powerful tool that can be used for containerizing applications. This course will focus on advanced Docker administration concepts, with demonstrations of some of these advanced concepts. In this course, you'll learn about continuous integration and how it relates to Docker, Docker Hub, Docker Compose, and Docker's lifecycle. Next, you'll examine Docker security challenges and how to configure security and Transport Layer Security options. You'll explore the Docker Hub and the process of building, managing, and distributing Docker images. You'll also learn about the Docker architecture and the Docker daemon. You'll move on to cover the Docker content trust, trust delegation, how to deploy a notary, and trust key management. Finally, you'll learn about storage management in Docker, including volumes, bind mounts, and tmpfs mounts, as well as how to administer Docker networking components, services, and containers.

Troubleshooting and debugging Docker issues are skills that are a must-have in a developer's arsenal. Use this course to learn about the 'art and science' of troubleshooting infrastructure solutions and some common troubleshooting strategies. Start by exploring some common Docker issues and their solutions before moving on to examining how to use the Docker log files to diagnose issues. You'll then discover different options for logging drivers learn how to troubleshoot issues with Docker images, Docker deployments, and deployments using Kubernetes, as well as some of the common tools used to troubleshoot Docker. You'll also investigate the steps involved in troubleshooting common issues with the Dockerfile, common Docker container naming issues, and common Docker communication issues. After completing this course, you'll have the skills and knowledge to troubleshoot and debug issues in Docker builds and deployments.

Performance engineering includes techniques to ensure that non-technical requirements such as latency, memory usage, and throughput are met. Docker containers can take advantage of performance engineering to ensure that they run efficiently and effectively. In this course, you'll learn about the history and purpose of performance engineering and techniques for using performance engineering with Docker containers. Next, you'll explore how to manage Docker, as well as some common Docker performance issues and how to resolve them. You'll move on to learn about some of the tools that can be used for monitoring and performance testing on Docker containers. Finally, you'll examine some examples of how to use the ManageEngine and Prometheus monitoring tools to monitor Docker containers and also use them to optimize a Docker container running MySQL and WordPress

Optimizing Docker performance occurs long before the containers are in a production environment. Optimization needs to be part of the initial design and planning process. In this course, you'll learn how to optimize the various sections of the Docker ecosystem. First, you'll examine why Docker container performance needs to be part of the initial design and planning process and some of the best practices for designing docker containers.
