Deploying a Static Rust App in a Barebones Docker Container
- vkjv 8y agoYou can wrap up the build and the copy with a multi-stage docker build. Something like the following. FROM rust:latest RUN rustup target install x86_64-unknown-linux-musl COPY . /src WORKDIR /src RUN cargo build --release --target=x86_64-unknown-linux-musl FROM scratch COPY --from=0 /src/target/x86_64-unknown-linux-musl/release/rust_docker_barebones /rust_docker_barebones ENTRYPOINT ["/rust_docker_barebones"] Although, I typically recommend _not_ using the scratch container unless you really need something that tiny. It makes debugging very difficult if you don't at a minimum have a shell and a package manager. Also, packaging up rust to be static like this can take some extra steps. For example, loading in root certificates.
