构建docker失败

Question

我有下面的代码配置 Dockerfile：

# Builder Stage
FROM rust:1.76.0 as builder
ENV SQLX_OFFLINE=true

# Create a new Rust project
RUN USER=root cargo new --bin jwt
WORKDIR /jwt/

# Copy and build dependencies
COPY Cargo.toml Cargo.lock ./entity/Cargo.toml  ./
RUN cargo build --release --locked
RUN rm src/*.rs

# Copy the source code and build the application
COPY . .
RUN cargo build --release --locked

# Production Stage
FROM debian:buster-slim
ARG APP=/usr/src/app

RUN apt-get update \
    && apt-get install -y ca-certificates tzdata \
    && rm -rf /var/lib/apt/lists/*

ENV TZ=Etc/UTC \
    APP_USER=appuser

RUN groupadd $APP_USER \
    && useradd -g $APP_USER $APP_USER \
    && mkdir -p ${APP}

COPY --from=builder /jwt/ ${APP}/jwt

RUN chown -R $APP_USER:$APP_USER ${APP}

USER $APP_USER
WORKDIR ${APP}


ENTRYPOINT ["./jwt"]  
EXPOSE 8000

docker-compose.yml 在这里：

version: '3'

services:
  api-rust:
    image: username/api-rust
    container_name: api-rust
    restart: unless-stopped
    environment:
      DATABASE_URL: ${DATABASE_URL}
      JWT_SECRET_KEY: ${TOKEN}
      JWT_MAXAGE: ${JWT_MAXAGE}
    build:
      context: .
      dockerfile: Dockerfile
    networks:
      - rust_app_network
      
  postgres:
    image: postgres:13
    container_name: postgres
    environment:
      POSTGRES_USER: ${POSTGRES_USER}
      POSTGRES_PASSWORD: ${POSTGRES_PASSWORD}
      POSTGRES_DB: ${POSTGRES_DB}
    volumes:
      - postgres:/var/lib/postgresql/data
    healthcheck:
      test: ["CMD", "pg_isready", "-h", "postgres", "-U", "${POSTGRES_USER}"]
      interval: 5s
      timeout: 5s
      retries: 5
    networks:
      - rust_app_network

  pgadmin:
    image: dpage/pgadmin4
    container_name: pgadmin
    environment:
      PGADMIN_DEFAULT_EMAIL: ${PGADMIN_DEFAULT_EMAIL}
      PGADMIN_DEFAULT_PASSWORD: ${PGADMIN_DEFAULT_PASSWORD}
      PGADMIN_LISTEN_PORT: ${PGADMIN_LISTEN_PORT}
    volumes:
      - pgadmin-data:/var/lib/pgadmin
    restart: always
    depends_on:
      - postgres
    networks:
      - rust_app_network

volumes:
  postgres:
  pgadmin-data:

networks:
  rust_app_network:

当我运行“docker-compose -f docker-compose.yml -f docker-compose.dev.yml up -d”时

有问题：

来自守护进程的错误响应：无法为容器创建任务：无法创建 shim 任务：OCI 运行时创建失败：runc 创建失败：无法启动容器进程：exec：“./jwt”：stat ./jwt：没有这样的文件或目录：未知

Answer 1

您要运行的二进制文件是什么？

COPY --from=builder /jwt/ ${APP}/jwt

因为你这样复制，所以你必须知道你要执行哪个文件。 例如

/jwt/somefile

是你要执行的文件

ENTRYPOINT ["./jwt"]  

->

ENTRYPOINT ["./jwt/somefile"]
