Docker, Inc

We asked Docker Captains what they wish more developers understood and some clear themes emerged: • Docker is more than just containers - it’s a comprehensive platform that improves the SDLC • Docker provides security to prevent vulnerabilities from sneaking in through unexpected ways • Docker has new solutions for AI developers Docker Captains work in cloud-native environments every day and speak from experience. What’s something you wish more devs knew?

If you're in the Barcelona area, make sure to check out this MWC / 4YFN session tomorrow!

As AI agents generate more code than ever, the real question isn’t just how fast you can ship, it’s whether you can trust what’s running in production. On the latest Stack Overflow Podcast, Docker COO Mark Cavage unpacks how Docker is focused on bridging that software supply chain trust gap - from making Docker Hardened Images free (and what “hardened” actually means), to Sandboxes, and coding agent updates. A thoughtful conversation about the systems behind the commands we take for granted - and what it takes to operate infrastructure at global scale. 🎧 Tune in: https://bit.ly/4bsnp7d

Security doesn’t stop at the base image. When we made Docker Hardened Images free, we raised the baseline for container security across the ecosystem. Now we’re extending that same rigor to system packages. With Docker Hardened System Packages, every package goes through the same secure pipeline as our images. That includes 8000+ Alpine packages - built from source, continuously patched, fully attested, and SLA-backed. Debian coverage coming soon. The same security standard, now applied to what’s inside the container. Learn more:

Still debugging Dockerfiles by rerunning builds and digging through logs? Join Reynald Adolphe (Microsoft / VS Code) for a VS Code Live session featuring Docker’s Remy Suen and Jonathan S. They will demo how to debug Dockerfiles directly in VS Code using the Docker DX extension. If you’re building images daily and troubleshooting the hard way, this session shows a faster, more interactive workflow in action. 📅 Thurs, March 5 11am ET Register / watch → https://lnkd.in/gqcUnDVZ

When AI writes more code, who takes responsibility for what ships? In the newest Ship Happens episode hosted by Per Ploug Krogslund, Arun Gupta (VP DevEx at JetBrains and Docker Captain) gets real about maintainer burnout, funding, and why OSPOs matter even more in the agent era. As AI generates more code, open source sustainability and governance move to the front lines. Tune in: https://lnkd.in/g_P4A-_Q

Apple Silicon just got a serious upgrade for local LLM development. vLLM has become a go-to for high-throughput LLM serving, and now Docker Model Runner supports it on macOS. That means you can run MLX models on an M-series Mac with the same OpenAI-compatible API (plus Anthropic-compatible APIs for tool workflows) using the Docker commands you already know. Pull a model. Run it. Docker picks the right backend. Get started with it on Docker Desktop 4.62+ on Mac. Learn more:

Running local models shouldn’t be complicated. Open WebUI now auto-detects Docker Model Runner for a fully self-hosted setup in minutes. Enable Model Runner, start OpenWebUI, and your models are instantly available in the browser - no extra config. Docker runs the models. Open WebUI gives you the interface. Read the walkthrough:

Congrats to Anil Madhavapeddy and your team on making the cover of CACM! This one’s relevant to every Docker user. Read through the articles to explore the technical foundations behind Docker - and the impressive, real-world systems their work helps power.
