# Raspberry Pi Dev Image Build This skill helps you build the Raspberry Pi development image locally by executing `act` within the running Devcontainer. ## When to use this skill Use this skill when you need to: - Build a fresh `netalertx-rpi-dev.img.xz` image. - Verify the build process locally before pushing to GitHub. - Ensure the build runs in the correct environment (Devcontainer). ## Prerequisites - **Devcontainer running:** Ensure the container `bfc542fa0ee1` is running (`docker ps`). - **Docker:** Must be installed and running on the host. ## Running the Build Run the following command on the **host machine**. This sends the build instructions into the container. ```bash docker exec -w /workspaces/rpi-image bfc542fa0ee1 bash -c "/workspaces/rpi-image/.devcontainer/scripts/build_local_dev.sh" ``` ## Command Breakdown 1. **Cleanup:** `rm -rf /tmp/artifacts` removes old artifacts to prevent permission errors. 2. **Act Build:** `act -j build-dev ...` runs the GitHub Action job locally. - `--container-options "--privileged"`: Required for loop mounting. - `--artifact-server-path`: Stores artifacts in a temp dir. 3. **Extraction:** `unzip` extracts the resulting zip file to the current directory. ## Artifacts - **Output:** A `.img.xz` file will be created in the root of the repository. - **Note:** The `act` command might report "Job failed" due to missing tokens for the Release step, but the artifact creation usually succeeds. ## Best Practices - Always verify the container ID (`bfc542fa0ee1`) matches your actual running devcontainer. - Do not run `act` directly on the host; it lacks the necessary tools and permissions.
