This book would not have been possible without the blessings of my late parents, and the continued support of my wife Mouli and son Arpan, both of whom had to often put up with my brusque and curt manner, as I worked on the book late in the evenings and on weekends, cutting out on family time.

I would like to thank the technical reviewers of the book: Indrajit Nandi, Debasis Maity and Sabyasachi Banerjee, all of whom took time out from their busy schedules to technically review the book and give me the reassurance that the book indeed fulfils the objectives for which it was written. My gratitude also goes out to a lot of other people who encouraged me during the writing of this book, none more so than my brother Prabal, who helped me with all the diagrams in the book, as well as my friends and colleagues who kept me on my toes by often asking me about the progress of the book, thereby implicitly nudging me along.

This genesis of this book lies in my struggle in trying to decipher and understand Docker while I was learning it and trying to find the answers to questions and doubts that came to my mind while I tried to wrap my head around all the new concepts and terminologies, often facing a sea of doubts with no shoreline in sight.

If this book helps in demystifying Docker for someone who is new to the technology, I would consider my job well done and my efforts more than adequately compensated.
