docker - Azure DevOps + Docker : 'apt-get' is not recognized as an internal or external command

Question

我是 Azure DevOps 的新手，正在尝试构建我的第一个完整管道，但在构建 Docker 镜像时遇到问题。

Docker 文件中的一行导致管道失败，即带有 apt-get 的一行!

你有办法解决这个问题吗？

这是我得到的错误(日志):

Step 11/25 : RUN apt-get update && apt-get install -y libgdiplus libc6-dev && dotnet dev-certs https;     dotnet publish --self-contained --runtime linux-x64 -c Debug -o out src/${PROJECT};
 ---> Running in 29ada69fe569
'apt-get' is not recognized as an internal or external command,
operable program or batch file.
The command 'cmd /S /C apt-get update && apt-get install -y libgdiplus libc6-dev && dotnet dev-certs https;     dotnet publish --self-contained --runtime linux-x64 -c Debug -o out src/${PROJECT};' returned a non-zero code: 1
'displayName:' is not recognized as an internal or external command,
operable program or batch file.
'failOnStderr:' is not recognized as an internal or external command,
operable program or batch file.
##[error]Cmd.exe exited with code '1'.

这是我的管道文件:

- script: |
    docker image build --no-cache --tag=registry.gitlab.com/iznogood/myproject/iznogood.myproject.httpapi:1.0.0 -f .\src\Iznogood.Myproject\Dockerfile .
    displayName: 'Build image'
    failOnStderr: true

这是 Docker 文件:

检查管道并验证您正在运行的操作系统。如果它是 Windows 镜像，apt-get 将不起作用。更改您的管道以使用 Linux 机器。
