Great book! Helped me to finish few projects based on Docker. Thank you Aymen!

I'v been using docker ecosystem for 1 year or so. I had tried to refer to various documentations available and purchased courses on Udemy, Linux Foundation as well but none of them is as comprehensive ,hands-on, practical use-case driven which this book covers. I will surely refer this to professionals working in area of SDN,NFV and using docker on a daily basis.

Need to get up to speed with #docker and #devops, I highly recommend "Painless Docker" (painlessdocker.com) by @eon01. A superbly nice guy.
