Build & Build

time docker build . -t rust-builder
alias rust-builder='docker run -it -v target:/home/rust/src/target  -v cargo-registry:/home/rust/.cargo/registry  -v cargo-git:/home/rust/.cargo/git -v "$(pwd)":/home/rust/src rust-builder'
rust-builder cargo build --release --bin bootstrap

Caching builds

You may be able to speed up build performance by adding the following -v commands to the rust-musl-builder alias:

-v cargo-git:/home/rust/.cargo/git
-v cargo-registry:/home/rust/.cargo/registry
-v target:/home/rust/src/target

You will also need to fix the permissions on the mounted volumes:

rust-musl-builder sudo chown -R rust:rust \
  /home/rust/.cargo/git /home/rust/.cargo/registry /home/rust/src/target
