For IT professionals. No previous Docker experience required.

 

About the technology

Docker is a simple idea that has revolutionized the software industry. You build small virtual environments, called containers, that contain an application and all its dependencies. Because a container provides everything your application needs to run, theyre portable, fast, and reliable in any cloud or on-prem platform. Docker smooths major modern IT challenges, including cloud migration, legacy app modernization, clean installs, continuous deployment, and much more.

 

Elton Stoneman is an architect at Docker, a Microsoft MVP and a Pluralsight author. He has used Docker since the earliest releases and helped organizations at every stage in their container journey. He is a regular speaker and workshop instructor at conferences, and distils many years of using and teaching Docker into this book.
