Reproducible ESP32 Firmware Development with Docker and Docker Sandboxes
Summary
Docker and Docker Sandboxes are used to make ESP32 firmware development more reproducible. The official espressif/idf image provides a pinned toolchain and environment, while Docker Sandboxes allow AI agents to operate inside isolated microVMs with their own Docker daemon, ensuring host safety. The article walks through baseline building, parallel environments, sandboxed AI agent workflows, and integration with CI for reproducible ESP-IDF workflows, with caveats about performance and serial port access.
