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.

A white square with a plus sign is positioned between "Docker" and "Kubernetes" in the main title.

I often share my wins—so here are some rejections too:
🧊 My #CNCF Ambassador application was rejected (because too many Ambassadors in Germany).
☕️ My @javaland.bsky.social talk was soft-rejected and put on the waiting list.
Now I get to pay for both JavaLand and KubeCon! 😅
