GitLab CI/CD构建Deb包时Docker镜像构建报错及路径问题求助

问题背景 #

尝试搭建GitLab CI/CD流水线构建并推送deb包时，遇到两个Docker相关错误：

错误1：Docker构建拉取debian:wheezy镜像失败 #

执行docker build -t generic-package-build-runner:v1时出现：

[+] Building 2.0s (3/3) FINISHED
 => [internal] load build definition from Dockerfile 0.0s
 => => transferring dockerfile: 36B 0.0s

错误2：Docker Compose构建找不到Dockerfile #

使用docker-compose.yml时出现：

[+] Building 0.0s (0/0)
unable to prepare context: path "/Users/it340/MyFolder/DebPackageGitLabDocker/Dockerfile" not found

当前使用的文件内容：

setup.sh

# change to our own mirror
echo "deb http://pkg.adfinis-sygroup.ch/debian/ wheezy main non-free contrib" > /etc/apt/sources.list  
echo "deb http://security.debian.org/ wheezy/updates main" >> /etc/apt/sources.list  
echo "deb http://pkg.adfinis-sygroup.ch/debian/ wheezy-updates main contrib non-free" >> /etc/apt/sources.list

# requirements
apt-get update  
apt-get -y install git dh-make build-essential autoconf autotools-dev  

docker-compose.yml

version: '3.7'

services:
  gitcicd:
    build: Dockerfile

DockerFile

FROM debian:wheezy 
ADD  setup.sh /opt/  
RUN  /bin/bash setup.sh

解决方案 #

针对错误1：debian:wheezy镜像无法拉取 #

• 原因：Debian Wheezy已停止支持超过7年，官方镜像仓库已移除该版本，且无适配当前主流CPU架构的镜像。
• 解决步骤：
  1. 替换基础镜像为仍受支持的Debian版本，比如debian:bookworm（稳定版）或debian:bullseye（旧稳定版），修改DockerFile：

     FROM debian:bookworm
     ADD setup.sh /opt/  
     RUN /bin/bash setup.sh
     

  2. 更新setup.sh中的源地址，适配新的Debian版本：

     # 替换为bookworm官方源（或你常用的镜像源）
     echo "deb http://deb.debian.org/debian/ bookworm main non-free contrib" > /etc/apt/sources.list
     echo "deb http://deb.debian.org/debian-security/ bookworm-security main non-free contrib" >> /etc/apt/sources.list
     echo "deb http://deb.debian.org/debian/ bookworm-updates main non-free contrib" >> /etc/apt/sources.list
     
     # 安装依赖
     apt-get update  
     apt-get -y install git dh-make build-essential autoconf autotools-dev
     

  3. 若必须使用Wheezy（不推荐），可尝试寻找第三方维护的旧镜像（如openjdk:7-wheezy），但此类镜像存在严重安全风险。

针对错误2：Docker Compose找不到Dockerfile #

• 原因：docker-compose.yml中build字段写法错误，直接写Dockerfile会被当作路径处理，而非文件名。
• 解决步骤：
  1. 若Dockerfile与docker-compose.yml在同一目录，修改build为当前目录（Compose会自动识别Dockerfile）：

     version: '3.7'
     
     services:
       gitcicd:
         build: .
     

  2. 若Dockerfile文件名非默认Dockerfile（比如你的文件是DockerFile，注意大小写），需显式指定：

     version: '3.7'
     
     services:
       gitcicd:
         build:
           context: .
           dockerfile: DockerFile
     

  3. 验证文件路径：确保DockerFile确实存在于/Users/it340/MyFolder/DebPackageGitLabDocker/目录下，注意Linux/macOS区分文件名大小写。
