I just completed the Docker Commandos v1.5 Asgard Mission! 🐳🛡️ Check out my certificate of completion: www.dockersecurity.io/commandos/in...

Prove your vulnerability exemptions are legitimate. VEX Attestations act as tamper-proof OCI referrers that travel with your container, automating compliance. ✅ Commando 7️⃣ RuinTan, the Immortal, grants invincible, verifiable protection cards to the innocent. 💀 More: dockersecurity.io/co...

Stop scanner fatigue! Use VEX (Vulnerability Exploitability eXchange) to formally exempt CVEs that aren't exploitable in your specific context. 🔇 Commando 6️⃣ Mina, the Undead Assassin, knows exactly which monsters are a threat and which are harmless. 🧛‍♀️ Learn more: dockersecurity.io/co...

Want to slash your attack surface to zero? Use Docker Hardened Images: FROM dhi.io/node:25 Instead of: FROM node:25 Hardened Images are not hard. Commando 5️⃣ Artemisia, the Amazonian Commander, guards the heavily fortified, zero-CVE district. ⚓ www.dockersecurity.i...

Don't just generate an SBOM—attach it to your image! Using --sbom=true during build ensures the artifact travels everywhere your container goes. 🪪 Commando 4️⃣ The Valkyrie issues permanent, tamper-proof ID cards at the gates of Asgard. 🛡️ Meet the team: dockersecurity.io/co...

Find the vulnerabilities before you deploy. Cross-reference your SBOM against real-time CVE databases: $ docker scout cves <image> Commando 3️⃣ Jack, the Cyborg Soldier, acts as the ultimate scanner, hunting monsters on the perimeter. 🤖 Meet the team: dockersecurity.io/co...

You can't patch what you don't know you have. Generating an SBOM gives you full visibility into every component of your software supply chain. 📋 $ docker sbom <image> Commando 2️⃣ Rothütle demands a list of all Asgard residents to hunt down hidden CVEs. Meet the team: dockersecurity.io/co...

Stop writing insecure Dockerfiles from scratch. 🛑 Use docker init to automatically generate production-ready, secure foundations based on best practices. That's how Commando 1️⃣ Gord, the Swordmaster, builds her impenetrable command center in Asgard. ⚔️ Meet the team: dockersecurity.io/co...

Docker Commandos landed at Rabobank! ⚔️🐳 Last week, I ran the v1.5 Asgard Mission workshop for ~30 engineers in the Netherlands—and 80% rated it 5/5! 🌟 Instead of dry security slides, we used a dark fantasy narrative to secure the container supply chain. 🧵👇

Docker Commandos coming to Cologne. 💪 On April 20–23 I'll be at @JCON.one with my workshop: ☕ »Java Supply Chain Security with Docker« SBOMs. Attestations. Docker Hardened images. Cologne is in Carnival mode—so we're bringing the energy. 🎟️ 10% off with ARABI-VIP-15 CC @docker.com

Guess who's a verified book author on Medium! aerabi.medium.com

Docker Hardened Images are now free! FROM dhi‌.io‌/node:24 From this moment on, you can use the near-zero-CVE Docker images as your base images, for free! Learn more here:

Do I make a good Norse God? Jfokus people have created this avatar for me as I’m going to join them to talk about Docker Security. What do you think my Norse God name would be? A’rabír?

Container Security Advent, day 3 is here! 🪔📩🌃🌲

Day 2 of the DevSecOps Advent blog is here! 🕯️🚪📩📜 They get a typed letter!

So… I started an Advent series that mixes Gothic Black Forest storytelling with container security tips, because clearly I've gone crazy. 🎩🌲💀🐋 Day 1 is live:

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.

🤯 Issue #24 of Git Weekly is LIVE! I was up until midnight finishing it, but it was worth it. 🏆 My book is an official DEVOPS DOZEN 2025 FINALIST! 🎉 Plus, a deep dive into 6 powerful git diff commands and news on the new India Edition print release. www.linkedin.com/pulse/24-git...

I wrote in my book "one good thing about Docker init is that it doesn't use GenAI". That's how much I love GenAI. 😅

This tweet is from 2 years ago, when I started writing the #Docker security book. It's finally coming out in 2 months. 📘🔐 Many thanks to #Packt for planting that idea in my head. Even though we eventually parted ways, the spark remained. ✨ CC @docker.com

How's this sticker art? Would you put it on your laptop?
