Dockerfile ERROR RUN strip target/release/ 在 Windows 上

Question

我正在按照一本教程指南进行操作，并且已成功生成 Rest API 响应

当我跑步时

docker build -t my_app . 

出现错误

 ERROR [builder 6/6] RUN strip target/release/my_app                                                                0.4s

 > [builder 6/6] RUN strip target/release/my_app:

Dockerfile:16
--------------------
  14 |     # do a release build
  15 |     RUN cargo build --release
  16 | >>> RUN strip target/release/my_app
  17 |
  18 |     # use a plain alpine image, the alpine version needs to match the builder
--------------------
ERROR: failed to solve: process "/bin/sh -c strip target/release/my_app" did not complete successfully: exit code: 1

这是我的 Dockerfile 的样子

# Start with a rust alpine image
FROM rust:1-alpine3.19 AS builder

# This is important, see https://github.com/rust-lang/docker-rust/issues/85
ENV RUSTFLAGS="-C target-feature=-crt-static"

# if needed, add additional dependencies here
RUN apk add --no-cache musl-dev

# set the workdir and copy the source into it
WORKDIR /app
COPY ./ /app

# do a release build
RUN cargo build --release
RUN strip target/release/my_app

# use a plain alpine image, the alpine version needs to match the builder
FROM alpine:3.19

# if needed, install additional dependencies here
RUN apk add --no-cache libgcc

COPY --from=builder /app/target/release/my_app /usr/local/bin/

ENV ADDRESS=0.0.0.0
ENV PORT=8080

WORKDIR /root

# set the binary as entrypoint
CMD /usr/local/bin/my_app

这是完整的日志

我是 Rust 新手，之前没有任何 Docker 经验，我只是想学习，使用 alpine 在 Rust 中构建一个小型 docker

Answer 1

如果您查看错误消息：

 > [builder 6/6] RUN strip target/release/my_app:
0.402 strip: 'target/release/cloud-app': No such file

您可以看到它正在为您的应用程序构建一个与您预期不同的名称。该名称在 Cargo.toml 中设置。检查 Cargo.toml 文件并适当设置目录。 （我希望它像

target/release/cloud-app

）。
