Kubernetes Windows 节点动态提供 Jenkins Agent

在前面两篇文档，在 Kubernetes 上动态创建 Jenkins Slave 和 Kubernetes 添加 Windows 节点提供 Jenkins 构建动态 Agent 的基础之上，本篇文档主要尝试在 Kubernetes 上动态提供 Windows 构建 Agent 。

1. 新增流水线

Kubernetes 与 Jenkins 集成部分可以参考上面的两篇文档，这里直接新建两条流水线进行测试。

windows - jenkins 内置的流水线示例

/*
 * Runs a build on a Windows pod.
 * Tested in EKS: https://docs.aws.amazon.com/eks/latest/userguide/windows-support.html
 */
podTemplate(yaml: '''
apiVersion: v1
kind: Pod
spec:
  containers:
  - name: jnlp
    image: jenkins/inbound-agent:windowsservercore-1809
  - name: shell
    image: mcr.microsoft.com/powershell:preview-windowsservercore-1809
    command:
    - powershell
    args:
    - Start-Sleep
    - 999999
  nodeSelector:
    kubernetes.io/os: windows
''') {
    node(POD_LABEL) {
        container('shell') {
            powershell 'Get-ChildItem Env: | Sort Name'
        }
    }
}

windows-dotnet

使用 dotnet 镜像进行构建

pipeline {
  agent {
    kubernetes {
      yaml """
apiVersion: v1
kind: Pod
metadata:
  name: windows
spec:
  containers:
  - name: jnlp
    image: jenkins/inbound-agent:windowsservercore-1809
    tty: true
  - name: windows-dotnet
    image: mcr.microsoft.com/dotnet/core/sdk:2.1
    tty: true
  nodeSelector:
    kubernetes.io/os: windows
"""
    }
  }
  stages {
    stage('Run on windows') {
      steps {
        container(name:'windows-dotnet'){
          bat 'dotnet -h'
        } 
      }
    }
  }
}

2. 查看结果

windows

windows-dotnet

查看 Windows 下载的镜像

docker images

Windows 节点的磁盘空间一定要很大才行。
