Docker

We asked Docker Captains what they wish more developers knew.
The themes were clear:

- Docker is more than just containers
- Security belongs in the development workflow.
- Docker has new solutions for AI developers

What’s something you wish you had learned earlier in your dev journey?

AI-assisted coding needs more than vibes; it needs containers and sandboxes - Stack Overflow

AI agents are writing more code than ever. Now the real question isn’t speed, it’s trust.

On the latest Stack Overflow Podcast, Docker COO Mark Cavage unpacks how Docker is bridging that trust gap, with DHI going free, Sandboxes, & coding agent updates.

Docker Hardened System Packages Secure your container stack from the base image down. Docker Hardened System Packages offer multi-distro, secure-by-default components with near-zero CVEs.

Security doesn’t stop at the base image.

Free Docker Hardened Images raised the baseline. Now we’re extending that rigor to what’s inside your container, with Docker Hardened System Packages: 8,000+ Alpine packages, source-built, patched, attested, & SLA-backed.
