At Big Data & AI World last week we heard developers loud and clear: They said: “We want to learn how to test GenAI apps!” 🧪 GenAI’s non-deterministic nature makes early and integration testing crucial. And, validating application logic that utilizes AI models is essential to ensuring high-quality apps. Today, we’re serving up best practices: ✅ Keyword matching – Simple but fragile ✅ Semantic similarity – More reliable but requires defining a threshold ✅ AI as a judge – Using LLMs to validate responses intelligently 👈 recommended 🙂 Thanks to Testcontainers, setting up these tests is easy—whether you’re building a GenAI app or a standard one. #GenAI #AI #Java #Testing #Testcontainers #Docker

Learnings from the Docker AI team! 👀 We are starting to see that LLMs can get overwhelmed when overloaded with options. That’s where mcp.run and Goose.ai come in. Now, you can seamlessly install and consume MCP servers—think of it as an MCP server marketplace—and get a streamlined way to run LLMs with MCP servers (different from Claude Desktop 😉). In this clip with Colin McNeil, see how it all works! 🎥 #AI #LLMs #MachineLearning #Docker

Last month, we asked our community what brings them joy compared to the challenges they face in their daily work. 💙 From your responses, we concluded that your biggest challenges (managing complexity across environments and ensuring security at every stage) keep you from having more time to code or learn something new. Do you agree? #Docker #DevLife #CloudNative

🤝 Docker works hand-in-hand with Kubernetes, enabling Cloudflare to automate and scale infrastructure effortlessly. Simplified orchestration, unparalleled control. Learn more about this powerful duo! #Kubernetes #Orchestration #DockerIntegration

Goodbye, unintended network access. Hello, built-in security. With Docker Engine 28, outbound traffic from containers is now restricted by default, helping developers minimize risk without extra configuration. More security, less work. Get the details on how we’re improving container networking. #Docker #Containers #Networking #DevSecOps #CloudNative

When you ask Docker's AI Agent to tell you a story about your running containers... c/o Djordje Lukic

Docker’s AI Agent: Your Smart Dev Companion Docker’s AI Agent can fetch the latest updates, optimize Dockerfiles, and even containerize projects for you. 🤖 Which feature are you most excited to try? 🔹 Instant release updates – Get the latest versions + changelogs automatically 🔹 Automated containerization – Let Docker’s AI Agent handle Dockerfile generation 🔹 Custom workflows – Extend it with MTP servers for advanced tasks 🔹 All of the above! 😍 Drop your vote and tell us what else you’d love to see! 👇 #Docker #AI #DevTools #Containers

Stop over-prompting! 🛑 Do foundation models really need #MCP prompts? We tested it—and the results were surprising. Instead of over-explaining, we focused on better tool descriptions. QR Codes: 🚫 Use the qrencode command ✅ Generate a QR code and write it to /thread/qrcode.png Headless Chrome: 🚫 Run a curl command ✅ Get the websocket URL Less prompting, more doing. Smarter tool definitions = smoother workflows. Try it in our MCP catalog! #Docker #AI #MCP #DevTools #Coding

Want to catch bugs before they ruin your day? Shift-left testing with Testcontainers lets you run local integration tests that are fast, reliable, and way less painful than debugging in staging. In our latest blog, we break down how shifting left can: ✅ Prevent costly late-stage defects ✅ Speed up development & deployments ✅ Improve software reliability And yes, we’ve got code examples. #ShiftLeft #Testing #DevOps #Docker #Testcontainers
