我正在尝试将我的rust服务器从Heroku移动到googlecloud或AWS。尽管我喜欢拥有一个
git push
只需指定一个buildpack就可以构建并部署到Heroku,这项服务对我来说并不划算。
我认为googlecloudrun和AWS弹性Beanstalk是潜在的替代品。
首先,我需要用一个静态二进制文件构建一个docker映像。
FROM rust AS build
WORKDIR /usr/src
RUN rustup target add x86_64-unknown-linux-musl
RUN apt-get update && apt-get upgrade -y && apt-get install -y build-essential git clang llvm-dev libclang-dev libssl-dev pkg-config libpq-dev musl-tools brotli
RUN USER=root cargo new loxe-api
WORKDIR /usr/src/loxe-api
COPY Cargo.toml Cargo.lock ./
COPY data ./data
COPY migrations ./migrations
ENV RUSTFLAGS="-C target-feature=+crt-static" # this should be set by the target, but just to be sure
RUN cargo build --release
COPY src ./src
ENV PKG_CONFIG_ALLOW_CROSS=1
ENV OPENSSL_INCLUDE_DIR="/usr/include/openssl"
RUN cargo install --target x86_64-unknown-linux-musl --path .
FROM scratch
COPY --from=build /usr/local/cargo/bin/loxe-api .
COPY data ./data
COPY migrations ./migrations
USER 1000
CMD ["./loxe-api"]
映像生成时没有错误,但如果通过docker run运行它,则会出现以下错误:
标准初始化_linux.go:219:exec user process caused:没有此类文件或
目录
通过用rust替换最后一步的基本映像,我检查了二进制文件和其他文件是否确实在映像中。他们是,我可以通过ls看到他们,但我也不能执行
loxe-api
当进入外壳时。
dockerd记录:

我还尝试从我的主机系统构建和执行。
我跑了
cargo run --target x86_64-unknown-linux-musl --release
target/x86_64-unknown-linux-musl/release/loxe-api
(从未执行)
我检查过二进制via的存在
du -h target/x86_64-unknown-linux-musl/release/loxe-api
:
35M target/x86_64-unknown-linux-musl/release/loxe-api
使用x86_64-unknown-linux-musl目标构建并运行一个新的cargo default项目。我想,libclang、brotli或一些argonautica库可能会导致这种情况不起作用。
下面是一个简化的Dockerfile,可以得到相同的结果。
