Docker with JVM Training Overview
This live, online Java Virtual Machine (JVM) projects training teaches attendees how to use Docker for their Java Virtual Machine (JVM) Projects to deliver reliable, containerized software as part of the automation process. After attending this course, students are prepared to immediately use Docker in their own JVM projects.
Location and Pricing
This course is taught as a private, live online class for teams of 3 or more. All our courses are hands-on, instructor-led, and tailored to fit your group’s goals and needs. Most Accelebrate classes can be flexibly scheduled for your group, including delivery in half-day segments across a week or set of weeks. To receive a customized proposal and price quote for online corporate training, please contact us.
In addition, some courses are available as live, instructor-led training from one of our partners.
Objectives
- Understand the tooling that helps with managing and abstracting Docker operations for JVM projects
- Implement typical developer workflows using Docker
- Build images for your JVM applications and distribute them to a Docker registry
- Write and execute different types of tests that use Docker containers as fixtures
- Automate the use of Docker from the IDE, the build process, and a CI/CD pipeline
Prerequisites
- Experience with Java application development or any other JVM language (such as Groovy or Scala)
- A working knowledge of Docker, specifically using the Docker CLI to manage images (pull, push, create) and containers (create, run, stop), Dockerfiles, and Docker Compose
- Basic familiarity with JUnit 5 (useful but not required)
