两阶段Rust Docker镜像编译chromiumoxide_cdp失败求助

我在搭建两阶段Docker镜像过程中，遇到chromiumoxide_cdp编译失败，错误表现为rustc进程被SIGKILL杀死，具体错误信息如下：

#16 798.3 error: could not compile `chromiumoxide_cdp`
#16 798.3
#16 798.3 Caused by:

我的Cargo依赖配置：

axum = { version = "0.6.18", features = ["ws"] }
anyhow = "1.0.71"
paris = { version = "1.5.15", features = ["no_logger", "macros"] }

reqwest = { version = "0.11.17" }
serde = { version = "1.0.163", features = ["derive"]}
scraper = "0.16.0"
serde_json = "1.0.96"
chromiumoxide = { git = "https://github.com/mattsse/chromiumoxide", features = ["tokio-runtime", "_fetcher-rusttls-tokio"], default-features = false, branch = "main"}
base64 = "0.21.0"

futures = "0.3.28" # needed for chrome oxide tokio handler thread
openssl = { version = "0.10.52", features = ["vendored"] }

Dockerfile内容：

################
##### Builder
FROM rust:slim as builder

WORKDIR /usr/src

# Create blank project
RUN USER=root cargo new app

# We want dependencies cached, so copy those first.
COPY Cargo.toml Cargo.lock /usr/src/app/

# Set the working directory
WORKDIR /usr/src/app

RUN apt update && apt install -y perl make musl-tools

## Install target platform (Cross-Compilation) --> Needed for Alpine
RUN rustup target add x86_64-unknown-linux-musl

# This is a dummy build to get the dependencies cached.
RUN cargo build --target x86_64-unknown-linux-musl --release

# Now copy in the rest of the sources
COPY src /usr/src/app/src/

## Touch main.rs to prevent cached release build
RUN touch /usr/src/app/src/main.rs

# This is the actual application build.
RUN cargo build --target x86_64-unknown-linux-musl --release

################
##### Runtime
FROM alpine:latest AS runtime

# Copy application binary from builder image
COPY --from=builder /usr/src/app/target/x86_64-unknown-linux-musl/release/app /usr/local/bin

EXPOSE 8000

# Run the application
CMD ["/usr/local/bin/app"]

解决建议 #

• 补充编译内存：SIGKILL通常是内存不足导致，可在builder阶段添加swap分区缓解：

  RUN fallocate -l 4G /swapfile && chmod 600 /swapfile && mkswap /swapfile && swapon /swapfile
  

• 限制编译线程：减少rustc并行编译的线程数，降低内存占用，修改构建命令为：

  RUN cargo build --target x86_64-unknown-linux-musl --release --jobs 1
  

• 改用稳定依赖版本：避免使用main分支的未稳定代码，替换chromiumoxide依赖为指定版本：

  chromiumoxide = { version = "0.12.0", features = ["tokio-runtime", "_fetcher-rusttls-tokio"], default-features = false }
  

• 调整镜像架构：放弃musl交叉编译，将runtime阶段改为基于Debian的镜像，直接构建原生二进制：

  # 修改Runtime阶段
  FROM debian:bookworm-slim AS runtime
  COPY --from=builder /usr/src/app/target/release/app /usr/local/bin
  

  同时删除builder中的rustup target add x86_64-unknown-linux-musl和构建命令中的--target x86_64-unknown-linux-musl参数。
