We cover pipeline automation from the basics through advanced use cases, pointing out common patterns and common pitfalls. A knowledge of basic Jenkins is assumed, but no prior experience with pipelines is required. After this course, you will have the tools to start automating your software build, test, and deployment activities following Jenkins best practices.

The course features four labs, one for each half-day, for hands-on exploration of the topics covered in lecture and discussion.
Declarative and scripted pipelines
Explores pipelines, both declarative and scripted, using common commands.
Distributed and concurrent builds
Build on multiple nodes. Parallel builds. Jobs that run on nodes other than master.Parallel execution of jobs. Sharing assets across parallel jobs;. Demonstraton of race condition.
Libraries
Refactor a pipeline and move reusable code to a shared library. Parameterize the library function to make it a more general utility. Consume the library in a pipeline and make use of the utility function.
Groovy
Write a pipeline that uses Groovy to configure and run a complex combination of build and test conditions.
