A docker container to build a OpenWRT firmware image. Useful for automation and CI/CD pipelines.
- Docker
- A Mac/Linux host (tested on macOS 13.0 and Ubuntu Github Runner)
- A working internet connection
To build an image you will need to specify the OpenWRT version (tag from repo) and the target device. The image will be saved in the output folder.
docker build --build-arg OPENWRT_VERSION=v22.03.2 --build-arg DEVICE=ea8300 -o output . | Argument | Description | Default |
|---|---|---|
| OPENWRT_VERSION | OpenWRT version to build | v21.02.2 |
| DEVICE | Target device to build the firmware for | ea8300 |
| SHOULD_ADD_HAASMESH | Whether or not to add HaasMesh to the image | 0 |
| CPUS | The number of CPUs/Threads to use for building | All Available |
It is normal for the build to take at least 30 minutes. The build process is very resource intensive and will use all available CPU cores.
To limit the number of cores used, you can use the CPUS build argument.
