About this course
This course develops practical capability in Packer. Its course-specific content covers Image pipeline model, Packer configuration, Provisioning steps, Build hygiene, followed by an applied project focused on build and validate a repeatable machine image. The lessons include concrete configuration, design, testing or operational decisions appropriate to the subject.
Who this is for
Administrators, developers and practitioners who work with Packer or plan to take on responsibilities in this area.
Before you start
Basic computer literacy and a foundational understanding of infrastructure as code & automation. Prior experience with the named product helps with the practical exercises.
Build and validate a repeatable machine image
Deliver build and validate a repeatable machine image. Use the module outcomes to state requirements, demonstrate a working result, test an expected failure or boundary case, and document assumptions and follow-up work.
