I have followed this suggestion to build a rust docker image. And this is my current Dockerfile:
FROM lukemathwalker/cargo-chef:latest-rust-alpine as chef
RUN apk update &&
apk add git cmake
WORKDIR /app
FROM chef AS planner
COPY ./Cargo.toml ./Cargo.lock ./
COPY ./src ./src
RUN cargo chef prepare
FROM chef AS builder
COPY --from=planner /app/recipe.json .
RUN cargo chef cook --release
COPY . .
RUN cargo build --release
RUN mv ./target/release/my_app ./app
FROM scratch AS runtime
WORKDIR /app
COPY --from=builder /app/app /usr/local/bin/
ENTRYPOINT ["/usr/local/bin/app"]
But I am getting the following error:
#13 91.72 CMake Error: CMake was unable to find a build program corresponding to "Unix Makefiles". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool.

I am able to run cargo build –release via the terminal on my computer without any issues

I ended up with the follwoing setup:
FROM rust:1.76.0-slim-bullseye as build
RUN apt-get update -y &&
apt-get install -y cmake libclang-dev musl-tools git g++
RUN rustup target add x86_64-unknown-linux-musl
# create a new empty shell project
RUN USER=root cargo new --bin app
WORKDIR /app
# copy over your manifests
COPY ./Cargo.lock ./Cargo.lock
COPY ./Cargo.toml ./Cargo.toml
# this build step will cache your dependencies
RUN cargo build --release
RUN rm src/*.rs
# copy your source tree
COPY ./src ./src
# build for release
RUN rm ./target/release/deps/*
RUN cargo build --release
# our final base
FROM debian:bullseye-slim
WORKDIR app
# copy the build artifact from the build stage
COPY --from=build /app/target/release/my_app .
# set the startup command to run your binary
EXPOSE 8000
CMD ["/app/my_app"]
