Day 1 is live:

A hand holds a blue book cover titled "Docker Kubernetes Security" by Mohammad-Ali A'râbi. The top left features the "DS DockerSecurity.io" logo and website, with "[v1.0.0]" on the top right. A white square with a plus sign is positioned between "Docker" and "Kubernetes" in the main title. Below, it details "Supply Chain Security + Runtime Protection" alongside a stylized white and light blue whale tail design. The author's name, "Mohammad-Ali A'râbi", is prominent at the bottom, with "Forewords by Hamida Rebai and Liran Tal" beneath it. A black keyboard is partially visible below the book, against a vibrant, blurred orange and red background.

A white piece of paper features a handwritten dedication in blue ink at the top, reading "To the best Captain in India," followed by the signature "Mohammad-Ali." Below this, printed in a gothic-style font, is the title "Docker and Kubernetes Security." Underneath the title is a black illustration of a stylized archer, possibly a man, riding a lion-like mythological creature with a bow and arrow. The paper is placed in front of a computer monitor displaying a vibrant, blurry red and orange abstract wallpaper with a row of indistinct application icons at the bottom.

Thank you, @aerabi.com, for gifting a copy of your newly published book, Docker and Kubernetes Security, and for bringing it all the way from Germany to Istanbul. I will go through it soon.

If you want to learn @docker.com and Kubernetes security, I highly recommend this book.
