High resource consumption on ``tutor images build`` by docker
-------------------------------------------------------------
This issue can occur when building multiple images simultaneously by Docker, issue specifically related to BuildKit.
Create a buildkit.toml configuration file with the following contents::
[worker.oci]
max-parallelism = 2
This configuration file limits the number of layers built concurrently to 2, which can significantly reduce resource consumption.
Create a builder that uses this configuration::
docker buildx create --use --name=<name> --driver=docker-container --config=/path/to/buildkit.toml
Replace <name> with a suitable name for your builder, and ensure that you specify the correct path to the buildkit.toml configuration file.
Now build again::
tutor images build
All build commands should now make use of the newly configured builder. To later revert to the default builder, run ``docker buildx use default``.
