| GitLab CI / U-Boot runner container |
| =================================== |
| |
| In order to have a reproducible and portable build environment for CI we use a container for building in. This means that developers can also reproduce the CI environment, to a large degree at least, locally. This file is located in the tools/docker directory. |
| |
| The docker image supports both amd64 and arm64. Ensure that the |
| 'docker-buildx' Debian package is installed (or the equivalent on another |
| distribution). |
| |
| You will need a multi-platform container, otherwise this error is shown:: |
| |
| ERROR: Multi-platform build is not supported for the docker driver. |
| Switch to a different driver, or turn on the containerd image store, and try again. |
| |
| You can add one with:: |
| |
| sudo docker buildx create --name multiarch --driver docker-container --use |
| |
| Building is supported on both amd64 (i.e. 64-bit x86) and arm64 machines. While |
| both amd64 and arm64 happen in parallel, the non-native part will take |
| considerably longer as it must use QEMU to emulate the foreign code. |
| |
| To build the image yourself:: |
| |
| .. code-block:: bash |
| |
| sudo docker buildx build --platform linux/arm64/v8,linux/amd64 -t your-namespace:your-tag . |
| |
| Or to use an existing container |
| |
| .. code-block:: bash |
| |
| sudo docker pull trini/u-boot-gitlab-ci-runner:jammy-20240227-14Mar2024 |
