在 Automation Assembler 中部署到 vSphere 时，可以分配一个静态 IP 地址，但必须注意不要在 cloudConfig 初始化命令和自定义规范之间引入冲突。

设计示例

以下设计可安全地应用静态 IP 地址，而不会在云模板初始化命令和自定义规范之间产生任何冲突。所有设计均包含 assignment: static 网络设置。

设计 云模板代码示例

将静态 IP 地址分配给没有 cloud-init 代码的 Linux 计算机

 
resources:
  wpnet:
    type: Cloud.Network
    properties:
      name: wpnet
      networkType: public
      constraints:
        - tag: sqa
  DBTier:
    type: Cloud.vSphere.Machine
    properties:
      flavor: small
      image: linux-template
      networks:
        - name: '${wpnet.name}'
          assignment: static
          network: '${resource.wpnet.id}'

将静态 IP 地址分配给具有 cloud-init 代码但代码不含网络分配命令的 Linux 计算机。

注意：无论是将 customizeGuestOs 自定义规范设置为 true 还是省略 customizeGuestOs 属性，都会应用 vSphere 自定义规范。

Ubuntu 示例

resources:
  wpnet:
    type: Cloud.Network
    properties:
      name: wpnet
      networkType: public
      constraints:
        - tag: sqa
  DBTier:
    type: Cloud.vSphere.Machine
    properties:
      flavor: small
      image: ubuntu-template
      customizeGuestOs: true
      cloudConfig: |
        #cloud-config
        ssh_pwauth: yes
        chpasswd:
          list: |
            root:Pa$$w0rd
          expire: false
        write_files:
          - path: /tmpFile.txt
            content: |
              ${resource.wpnet.dns}
        runcmd:
          - hostnamectl set-hostname --pretty ${self.resourceName}
          - touch /etc/cloud/cloud-init.disabled
      networks:
        - name: '${wpnet.name}'
          assignment: static
          network: '${resource.wpnet.id}'

CentOS 示例

resources:
  wpnet:
    type: Cloud.Network
    properties:
      name: wpnet
      networkType: public
      constraints:
        - tag: sqa
  DBTier:
    type: Cloud.vSphere.Machine
    properties:
      flavor: small
      image: centos-template
      customizeGuestOs: true
      cloudConfig: |
        #cloud-config
        write_files:
          - path: /test.txt
            content: |
              deploying in power off.
              then rebooting.
      networks:
        - name: '${wpnet.name}'
          assignment: static
          network: '${resource.wpnet.id}'

将静态 IP 地址分配给具有 cloud-init 代码同时代码包含网络分配命令的 Linux 计算机。

customizeGuestOs 属性必须为 false。

基于引用映像部署时，将静态 IP 地址分配给具有 cloud-init 代码同时代码包含网络分配命令的 Linux 计算机。

customizeGuestOs 属性必须为 false。

此外，云模板不得包含 ovfProperties 属性，该属性会阻止自定义。

          assignment: static
          network: '${resource.wpnet.id}'

实施后操作自定义

与初始部署一样，实施后操作也可能包括网络配置。要在实施后操作期间跳过自定义，请添加以下属性：

customizeGuestOsDay2: false

不起作用或可能会产生不想要的结果的设计

  • cloud-init 代码不包含网络分配命令，且 customizeGuestOs 属性为 false。

    既没有初始化命令也没有自定义规范用于配置网络设置。

  • cloud-init 代码不包含网络分配命令，并设置了 ovfProperties 属性。

    初始化命令不存在，但 ovfProperties 阻止了自定义规范。

  • cloud-init 代码包含网络分配命令，但 customizeGuestOs 属性缺失或设置为 true。

    应用自定义规范与初始化命令冲突。

有关 cloud-init 和自定义规范的其他解决办法

部署到 vSphere 时，还可以自定义映像，以解决 cloud-init 和自定义规范的冲突。有关详细信息，请参见以下外部存储库。
