How to limit `docker buildx build` concurrency
Raw
1.docker-buildx-build-concurrency.md

If your computer is running out of memory during a docker build, or if the build is CPU intensive, you might want to try building one architecture at a time.

When creating the builder instance, specify a buildkitd config file with --config that limits the concurrency.

Create buildkitd.toml:

[worker.oci]
max-parallelism = 1

And run:

docker buildx create --use --name multiarch-limit --node multiarch-limit0 --config buildkitd.toml

Future builds should hopefully not crash with out of memory errors. :)

Documentation: https://docs.docker.com/build/buildkit/configure/#max-parallelism

buildkitd.toml
[worker.oci]
max-parallelism = 1
