Rust 容器化
多阶段构建（推荐）
# 构建阶段
FROM rust:1.75 AS builder
WORKDIR /app
COPY Cargo.toml Cargo.lock ./
COPY src ./src
RUN cargo build --release
# 运行阶段
FROM debian:bookworm-slim
RUN apt-get update && apt-get install -y ca-certificates && rm -rf /var/lib/apt/lists/*
COPY --from=builder /app/target/release/my-app /usr/local/bin/
CMD ["my-app"]
Alpine 版本
FROM rust:1.75-alpine AS builder
WORKDIR /app
RUN apk add --no-cache musl-dev
COPY . .
RUN cargo build --release
FROM alpine:3.18
COPY --from=builder /app/target/release/my-app /usr/local/bin/
CMD ["my-app"]
小结
| 要点 | 说明 |
|---|---|
| 多阶段构建 | 减小镜像 |
| 基础镜像 | debian-slim 或 alpine |
| 静态编译 | RUSTFLAGS='-C target-feature=+crt-static' |
