运行Docker Compose构建Schemathesis服务时遇构建失败错误求助

项目结构 #

• docker-compose.yml：自定义Docker Compose配置文件
• schemathesis：包含源代码和Dockerfile的目录

docker-compose.yml内容 #

version: '3'
services:
  schemathesis:
    build: ./schemathesis
    ports:
      - "8180:80"    
    networks:
      - default

schemathesis目录下的Dockerfile内容 #

FROM python:3.10-alpine

LABEL Name=Schemathesis

WORKDIR /app

RUN addgroup --gid 1000 -S schemathesis && \
    adduser --uid 1000 -D -S schemathesis -G schemathesis -s /sbin/nologin

COPY --chown=1000:1000 pyproject.toml README.rst src ./

RUN apk add --no-cache --virtual=.build-deps build-base libffi-dev curl openssl-dev && \
    curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y && \
    source $HOME/.cargo/env && \
    pip install --upgrade pip && pip install --no-cache-dir ./ && \
    apk del .build-deps && \
    rustup self uninstall -y

# Needed for the `.hypothesis` directory
RUN chown -R 1000:1000 /app

USER schemathesis
ENTRYPOINT ["schemathesis"]

执行命令后的错误 #

执行sudo docker-compose up --build时，报错：ERROR: Service 'schemathesis' failed to build，具体错误输出如下：

解决方案 #

错误原因 #

Alpine镜像无法访问官方软件源，导致找不到指定的依赖包，同时缓存中存在损坏的源信息。

解决步骤 #

1. 清理构建缓存
   执行命令清除旧的构建缓存，避免缓存干扰：

sudo docker-compose build --no-cache

如果需要更彻底清理Docker缓存，可执行：

sudo docker system prune -a

2. 更换Alpine软件源
   如果网络访问官方源持续异常，修改Dockerfile，在apk add前添加更换国内镜像源的命令，示例如下：
   修改后的Dockerfile第6步RUN块：

RUN sed -i 's/dl-cdn.alpinelinux.org/mirrors.aliyun.com/g' /etc/apk/repositories && \
    apk add --no-cache --virtual=.build-deps build-base libffi-dev curl openssl-dev && \
    curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y && \
    source $HOME/.cargo/env && \
    pip install --upgrade pip && pip install --no-cache-dir ./ && \
    apk del .build-deps && \
    rustup self uninstall -y

3. 检查网络连通性
   验证主机是否能正常访问Alpine官方源：

curl -I https://dl-cdn.alpinelinux.org/alpine/v3.17/main/x86_64/APKINDEX.tar.gz

若返回200状态码则网络正常，否则需排查防火墙、代理等网络设置。
