Welcome to the April 2025 edition of Docker Navigator. Missed an issue? Read past issues in our collection.
Welcome to another issue of Docker Navigator! From running large language models on your Mac to testing smarter with Testcontainers, this month we’re all about giving you the tools to build, break, and rebuild — with speed and security.
You’ll find tips for spinning up GenAI experiments, building secure pipelines with Google Cloud, and even creating a Snake AI game in your browser (because learning should be fun, right?). Plus, we’re spotlighting updates from the Docker community, new training events, and where to find us IRL.
Run LLMs locally with Docker: A quickstart guide to Model Runner
Now available in Beta with Docker Desktop 4.40 for macOS on Apple silicon, Model Runner makes it easy to pull, run, and experiment with LLMs locally.
Shift-left testing with Testcontainers: Catching bugs early with local integration tests
Learn how integration tests can help you catch defects earlier in the developer’s inner loop and how Testcontainers can make them feel as easy as unit tests.
Innovate fearlessly: Secure, fast development with Docker and Google Cloud
Discover how integrating built-in security empowers teams to confidently build, deploy, and scale, reducing risks without sacrificing agility.

Dive deep
Docker’s AI Agent: Your smart dev companion
With Gordon, you can enhance your productivity as a developer to optimize Docker files, understand complex syntax, and containerize applications. We’ll show you how to use Gordon, demo a few of its features, and show how you can use MCP to enhance its capabilities.
Turn your Mac into an AI playground with Docker Model Runner
Docker’s Model Runner enables developers to run large language models (LLMs) locally inside Docker Desktop. This makes it easy for developers to start using LLMs, eliminates cloud dependencies, reduces latency, and gives developers full control over AI inference.
Master Docker and VS Code: Supercharge your dev workflow
Get step-by-step instructions on how to pair VS Code and Docker to streamline your development processes.
Learn how to use Testcontainers to run containers programmatically in your preferred programming language.
Demo series: Unlock the full power of Docker
Learn about Docker’s suite of products and how we’re helping teams increase developer productivity, ensure security, and leverage enterprise-grade solutions.
The future is non-deterministic — Michael Donovan, Docker
Listen in as Michael Donovan, VP of Product at Docker, explores how non-deterministic solutions, powered by Agentic Workflows, can change the way we build everything from developer tools to automated tests to microservices.
Around the Community
Check out the Docker Forums
Looking for help, curious about how others are using Docker, or want to share something cool you built? The Docker Forums are a great place to explore new ideas, ask questions, and collaborate with fellow developers.
Here’s what’s happening in the community:
- Real-world troubleshooting — A user shared an issue running Pi-hole as a DNS server in a container. Forum members and Docker moderators teamed up to guide them to a fix.
- r/docker is back! — After a wave of spam and lack of moderation, the r/docker/ Reddit community has rebooted. Thanks to the efforts of the community the subreddit has:
- 8 new moderators
- Active threads and discussions
- A Docker Captain helping lead the way
Wherever you join in, one thing’s for sure — you’re never coding alone.
