Guided Project

Containerize Java Microservices with Docker V2

Gilbert Kwan

In this hands-on guided project, you’ll learn how to run Java microservices using Docker. You’ll learn how to construct Dockerfiles, create Docker images using the docker build command, run an image as a Docker container using the docker run command, and learn how and why it’s essential to externalize the server configuration.

In just about an hour, you’ll gain essential containerization skills to grow your career.

This lab provides access to a Cloud-based IDE that has all of the required software, such as Docker and OpenShift, preinstalled. All you need is a recent version of a modern web browser to complete this project.
