如何修复Jenkins(在Windows上)中的Docker错误？

我正试图进入Jenkins，但我现在被困在教程https://www.jenkins.io/doc/pipeline/tour/hello-world/的第一步几个小时。
我按照说明在Windows机器上安装了JDK和Docker Desktop。对于Docker Desktop，我还需要用Ubuntu安装WSL 2。我创建了一个示例GitHub Repo，其中只有一个Jenkinsfile，包含教程中的示例代码：

/* Requires the Docker Pipeline plugin */
pipeline {
    agent { docker { image 'python:3.10.7-alpine' } }
    stages {
        stage('build') {
            steps {
                sh 'python --version'
            }
        }
    }
}

如果我启动一个连接到GitHub仓库的Jenkins管道并试图构建它，我会得到以下错误：

当我用agent any替换agent { docker { image 'python:3.10.7-alpine' } }时，构建工作正常，但在python上当然失败了--因为Python版本没有安装。
我的研究只是让我发现Windows和运行Docker容器存在问题，难道真的不能在Windows机器上简单地遵循Jenkins的第一个教程页面吗？

docker

遗憾的是，代理“docker“在Windows托管的Linux环境中不兼容。
这是一个已知的问题安静了一段时间，任何努力，使一个持久的修复失败。
主要问题是Windows和Linux文件路径之间的不兼容。因此经常报告错误：

"Error: docker: Error response from daemon: the working directory 'C:/Jenkins/workspace/testspace/' is invalid, it needs to be an absolute path."

快速学习Jenkins教程的唯一方法是使用Docker CLI（命令行）命令。继续学习教程的基本示例如下所示：

pipeline {
agent any
    stages {
        stage('build') {
            steps {
                script {
                   /* the return value gets caught and saved into the variable MY_CONTAINER */
                   MY_CONTAINER = bat(script: '@docker run -d -i python:3.10.7-alpine', returnStdout: true).trim()
                   echo "mycontainer_id is ${MY_CONTAINER}"
                   /* python --version gets executed inside the Container */
                   bat "docker exec ${MY_CONTAINER} python --version "
                   /* the Container gets removed */
                   bat "docker rm -f ${MY_CONTAINER}"
                        }
                    }
                }
            }
        }

与Jenkins教程脚本相比，有两个主要更改：
1.基于Windows的系统应该使用bat而不是sh来执行批处理命令。
1.避免使用代理“docker“并将其替换为any
