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
