About the Author

Neependra Khare is currently working as a principal performance engineer in Red Hat's system design and engineering team. He has more than 11 years of IT experience. Earlier, he worked as a system administrator, support engineer, and filesystem developer. He loves teaching. He has conducted a few corporate training sessions and taught full semester courses. He is also a co-organizer of the Docker Meetup Group, in Bangalore, India.

He lives with his wife and two-year-old daughter in Bangalore, India. His Twitter handle is @neependra and his personal website is http://neependra.net/. He has also created a website for the book, which you can visit at http://dockercookbook.github.io/.

I would like to thank my parents who fought all odds and made me the person I am today. My wife, Kanika, has been the first and best support for this book. She took care of our daughter, Navya, when I was away writing this book.

It has been a bigger piece than expected, as new features in Docker and the ecosystems around it were evolving very fast. I have learned a lot during the process and the Docker community (blogs, IRC, mailing list, and meet ups) has been of great help.

I am thankful to all the reviewers of the book, who gave their valuable time to go through the content, pointed out my mistakes, and provided me with great suggestions.

I would also like to thank my current employer who gave me some time to work on this book and my coworker Jeremy Eder (@jeremyeder) from whom I learned a lot.
