Someone was wrong on the internet, so I built a Temporal Docker extension
6/11/2026
The post details the development of a Docker Desktop extension for Temporal. It covers the initial concept of embedding the Temporal UI, the realization that a more focused approach was needed based on Docker's extension design guidelines, and the final implementation. The extension starts a `temporal-dev` container using `temporalio/temporal:latest`, configures gRPC on `localhost:7233` and Temporal Web on `localhost:8233`, uses SQLite for persistence in a Docker volume, and includes a readiness check panel and a 'Clear History' button for local development resets. The UI design evolution is also discussed, moving from an iframe approach to a more focused, native experience.
