Yesterday I searched "Docker Captains" on Google (to find the catalog), and realized my Medium blog on becoming a Docker Captain is the second result. So, I gave it an edit:

Now you can buy signed copies of my book directly on the website: 📘✍️ buy.dockersecurity.io

The supply chain attack on NPM was the largest... so far! This article breaks it down and covers defense tips against the next one: dev.to/aerabi/the-l...

Docker Security book's latest foreword was written by none other than @lirantal.com the Yoda Bearer! 🐳🧢 I'm incredibly honored he stepped in at the very last moment to make this book more special. 🙏 📘 Launching Oct 1st → DockerSecurity.io

Got my first endorsement for Docker and Kubernetes Security! 🚀 Huge thanks to Docker Captain & open-source contributor Pradumna Saraf for the kind words. 🙏 @pradumnasaraf.dev 📘 Launching Oct 1st → DockerSecurity.io

Printing @docker.com cheatsheets for tomorrow's Docker workshop at JobRad. We will cover the following topics: 1️⃣ Docker Init 2️⃣ Docker Bake 3️⃣ Docker SBOM 4️⃣ SBOM Attestations 5️⃣ Docker Scout 6️⃣ Docker Debug 7️⃣ Docker Model Runner 8️⃣ Ask Gordon 9️⃣ Docker MCP Toolkit 🔟 CAgent

Happy Monday & September! 🎉 Finally launched my new personal site (it was about time 😉): aerabi.com How do you like it?

New Docker and Kubernetes Security stickers arrived! 🎉 Finish the CVEs with SBOMs!

Getting ready for our #cTENcf party! The @cncf.io is turning 10 this year, and we celebrate it in our chapter in Freiburg on October 2nd! What programs do you expect?

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?

Which cover do you like better? Whale or shield? 🐳🛡️

Docker's blog entry on WeAreDevelopers features a photo of everyone's favorite Francescos and I. www.docker.com/blog/...

So, I got a shiny badge for conducting a workshop at WeAreDevelopers. The workshop was a deep dive into a few new Docker features: - docker init - docker sbom - docker scout - docker buildx bake 🎂 - docker ai - docker model Should I do a video version of it?

Should I do a Shao Kahn version of the book "Docker and Kubernetes Security"? Secure Earthrealm against the Outworld invasion. 😅 #MortalKombat

Finally honored to met @francescociulla.bsky.social and @fcorti.bsky.social! 🍕🇮🇹 At the @docker.com booth during @wearedevelopers.bsky.social! 🐳 I stayed there long to sabotage their secret Italian conversation. 😎

So, I arrived! 🐳

In April, I wrote an article on git's 20th birthday. Today, it got the 10th clapper! itnext.io/20-git-tip...

My new blog post on 7 essential git commands is here! dev.to/aerabi/7-basi...

Git Weekly #19 is live; drafted somewhere between train platforms and existential dread. 🚉 This week: GPG-signing your #git commits. Because unlike this app, your commits should be decentralized and trustworthy. 😎 CC @bsky.app 👉 git-weekly.com/19

Hurray! 🎉 My article on Docker‌izing Java apps #securely is published on JAVAPRO! ☕ There, I covered the following things: - 🐳 docker init - 📦 docker sbom - 🔍 docker scout CC @docker.com 👉 Check it out here: javapro.io/2025/07/03/h...

15 years later, I still can't stop playing #Fallout: New Vegas. Which games do you play now? @fallout.bethesdastudios.com

The @docker.com's account is always right. 😅 Docker init is a great tool, especially as it doesn't use GenAI, so it's deterministic. I wrote about using `docker init` with Java, and it will come out in July on #JavaPro.

Need a clean Docker setup fast? Docker Captain @aerabi.com recommends: 'docker init' It auto-generates: 🔹 Dockerfile 🔹 .dockerignore 🔹 compose.yaml 🔹 README.Docker.md #Docker #DevTips #DockerCaptainInsights #Containers #CLI

I can't sleep because I want to get to my laptop and automate the shit out of everything. 😅 I'm blogging on: - 📝 git-weekly.com - ✍️ Medium - 💻 DEV.to - 💼 LinkedIn. I'm posting on: - Twitter - BlueSky - Threads - Mastodon - LinkedIn - Instagram. All manually! ☠️

June 2025 goals: - 🏝️ Get back to work after 3 weeks off - 🤖 Organize a @docker.com meetup on Docker Model Runner - 📘 Finalize chapters 4 and 5 of my Docker Security book I was so much in vacation mode, I didn't do a May goal. 😅

A new Git-Weekly issue is here! 🌴☕ I wrote this article initially in 2022 on Medium, which was read 2.3k times and made me $50. Today, I rewrote the article, burning under the sun's rays in Mallorca, giving it another life. 🌞 git-weekly.com/18

Yeehaw! I'm speaking at #PlatformCon2025 — and so is Kelsey Hightower! No big deal… just sharing the stage (virtually) with legends. Join 40,000+ platform engineers from June 23–27 for the biggest event in platform engineering. Register: platformcon.com#PlatformCon2025

🏗️ Docker tip #24. Build multi-platform images in one go using Docker Buildx. For example: $ docker buildx build --platform linux/amd64,linux/arm64 -t you/app:1.0 --push . This builds an image for x86_64 and ARM and pushes a multi-arch manifest. One image, any architecture. #DockerHour

🚀 Docker tip #23: Kickstart new projects with `docker init`. This handy command auto-generates: - Dockerfile, - .dockerignore, - docker-compose.yaml, - and more. It’s like having a template ready: saves time and ensures best practices from the start. #DockerHour

New Git Weekly is out! 🧠⚔️ Shao Kahn tried to merge the Earthrealm into the Outworld. You're just trying to merge two branches. But conflicts? Oh, they will happen. Learn how to resolve them like a warlord using git mergetool. 📘 git-weekly.com/17 #git #devtools #GitWeekly

🛡️ Docker tip #22. Use Docker Scout view on Docker Desktop to check your images' score, and try to fix them to get an A! #DockerHour @docker.com

🔖 Docker Tip #21: Avoid using the :latest tag for images in production. Always pin to a specific version (e.g. myapp:1.4.2) so you know exactly what's running. Or even better, create a local version of the upstream image and use that one to have more control over its versioning. #DockerHour

How do you like my new book cover?

📁 Docker Tip #20: Use a .dockerignore file to keep unnecessary files out of your build context. A smaller build context means faster builds. Only send what's needed to the daemon, and ignore the rest. #DockerHour

🧹 Docker tip #19. To remove all of your Docker images, do the following: $ docker rmi $(docker images -q) This `docker images -q` lists all of the images, and the output is fed to `docker rmi`, which is for removing images. #DockerHour

🧰 Docker tip #18. Use Slim Toolkit to build slim Docker images: $ slim build --target archlinux:latest --tag archlinux:curl --http-probe=false --exec "curl checkip.amazonaws.com" Learn more here: github.com/slimtoolk...#18. #DockerHour

🏋️ Docker tip #17. Always use the slim version of Docker images where possible, especially as a base image. FROM python:3.11-slim Less packages = more security. Credit: Tip from @bretfisher.com #DockerHour

🎂 Docker tip #16: Use Docker Buildx Bake to store your build configuration as code. $ docker buildx bake You need a docker-bake.hcl file for his command to work. #DockerHour

🐳 Docker tip #15: When building a Docker image, the parameter is not the Dockerfile's path, but the build context. You can have a different path for Dockerfile and build context: $ docker build -f path/to/Dockerfile path/to/context

My new toys have arrived! Should I record an unboxing video? 📦 📹

🔒 Docker tip #14: Use official Docker images as base image whenever possible. These images are maintained actively and are considered to be most secure. 🔐 #DockerHour ⏳ DockerSecurity.io

🏗️ Docker tip #13: Use arguments in your Dockerfile for things like your base image's tag. This way you won't need to change the Dockerfile upon every update to the base image. $ docker build --build-arg BASE_IMAGE_TAG=20.04 -t my-image . #DockerHour ⏳

Happy May the 4th, to the ones who celebrate it! 🎊 As a gift, this is my article on git push --force vs --force-with-lease: itnext.io/git-force-...

👻 Docker tip #12: Clean up your Docker resources to free up some disk space every once in a while. - docker container prune - docker image prune - docker volume prune - docker system prune The last one deletes almost everything. 💣 #DockerHour ⏳

🔒 Docker Tip #11: To restrict container capabilities on Kubernetes, use "security context". #ContainerSecurity #DockerHour ⏳ DockerSecurity.io

I had amazing birthday gifts this year! 1️⃣ An Amazon Kindle, and the first thing I tested on it was of course my DockerSecurity.io book! 📖 2️⃣ A handmade Mortal Kombat controller-holder from Iran! Do you read tech books on Kindle?

🔒 Docker Tip 10: Enhance #Docker security by limiting container capabilities with "--cap-drop" and "--cap-add" options: $ docker run --cap-drop=ALL -p 8080:8080 my-node-app #DockerHour ⏳ DockerSecurity.io

🖇️ Docker Tip #9: After running a Docker container in detached mode, you can attach to it with the following command: $ docker attach <container-id> It's different than `docker exec` as it will attach to the original process. #DockerHour ⏳
