构建 Rust Rocket Docker 镜像时出错

Question

我遵循了 this 建议来构建 Rust docker 镜像。这是我当前的 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"]

但是我收到以下错误：

我可以通过计算机上的终端运行 Cargo build --release ，没有任何问题

Answer 1

我最终进行了以下设置：

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/arnak .

# set the startup command to run your binary
#RUN /app/arnak
CMD ["/app/arnak"]
EXPOSE 8000
