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. To build the image yourself
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 build -t your-namespace:your-tag .
sudo docker buildx build --platform linux/arm64/v8,linux/amd64 -t your-namespace:your-tag .
Or to use an existing container
