zephyrproject-rtos/docker-image

Zephyr Docker Image is a Docker image designed for Zephyr RTOS development and continuous integration.

The project addresses the need for a complete, pre-configured development environment for the Zephyr RTOS project. It provides three distinct images: a CI base image containing tools for CI operation, a CI image that adds the Zephyr SDK, and a developer image that includes additional utilities for local development. The approach bundles toolchains for all supported architectures and testing tools into ready-to-use containers, eliminating the need to manually install and configure dependencies.

Developers should choose this image if they need a full upstream Zephyr environment with support for multiple architectures and comprehensive testing capabilities. It suits teams running CI pipelines or developers working on Zephyr samples and tests who want a consistent, reproducible build environment. The README explicitly recommends the Embedded Containers project's Zephyr image as an alternative for downstream CI or local development targeting a specific architecture, noting that alternative as smaller and more focused. The developer image includes a VNC server for testing display sample applications, and the images support SSH agent forwarding for accessing restricted repositories.

The project maintains active development with regular updates to support current and long-term support Zephyr versions. Images are published to both GitHub Container Registry and DockerHub, providing multiple distribution channels. The codebase is written primarily in Shell, reflecting its focus on container configuration and build automation.
