Abstract for Atlanta Docker Meetup

Panamax - Docker Management for Humans

An open-source project that makes deploying complex containerized apps as easy as drag-and-drop.

Join me in discovering Panamax, and find out how its functionality will enhance your use of Docker and simplify common pain points. Docker is good, but Panamax makes it awesome. I will introduce Panamax, and take you on a journey where we will create containerized applications, and then share the applications with our friends. I will also touch upon the basic architecture and underpinnings of Panamax. Panamax is open-source, so you can also learn how to contribute and stay involved as new features are added.
