Building with Rust

Make a buildenv image

make base-images
docker buildx build -t rust-buildenv .

Prepare a project workspace

Clone some source tree into the workspace/src directory:

git clone --depth=1 https://github.com/BurntSushi/ripgrep.git workspace/src

Create workspacefs.override.yaml:

cat <<EOF >workspace/workspacefs.override.yaml
cache:
  negative:
    excludes:
      - .cargo
EOF

Build with worker containers

Build it with worker containers:

concc-boot -C workspace -i gcc-buildenv -s scripts \
  concc -C src \
  'env RUSTC_WRAPPER=concc-exec cargo build --release -j $(concc-worker-pool limit)'

Specify worker hosts when building with remote worker containers:

concc-boot -C workspace -i gcc-buildenv -s scripts -w remote \
  concc -C src \
  'env RUSTC_WRAPPER=concc-exec cargo build --release -j $(concc-worker-pool limit)'

where remote must be accessible via SSH.

Using docker stats, you can confirm that build jobs will be distributed to the worker containers.

rustc will be executed on worker containers. Other jobs like downloading crates will be performed on the user container.
