Ansible - 标记 Azure 运行的虚拟机

【中文标题】Ansible - 标记 Azure 运行的虚拟机【英文标题】：Ansible - Tagging Azure running VMs 【发布时间】：2019-02-06 19:49:54 【问题描述】：今天，我一直在努力寻找从 Ansible 自动标记 Azure 中正在运行的 VM 的最佳方法。
第一种方法是使用azure_rm_virtualmachine 模块，但在部署新虚拟机时它可以正常工作。当 VM 启动并运行时，这是另一个历史记录，主要是在使用自定义映像完成部署时。
- name: Tag my VM
azure_rm_virtualmachine:
resource_group: myresourcegroup
name: myvm
admin_username: ansible
admin_password: mypassword
virtual_network_name: myvnet
virtual_network_resource_group: myvnetrsg
vm_size: Standard_D2_v2
state: present
started: no
append_tags: True
image:
name: mycustomimage
resource_group: myimagesrsg
tags:
env: "dev"
请参阅：https://github.com/ansible/ansible/issues/35235 在 2.7 中已解决，但仍无法使用自定义图像。
那么问题是如何处理正在运行的虚拟机？如何更换旧标签并添加新标签？
【问题讨论】：
【参考方案1】：问题是使用azure_rm_deployment 和azure_rm_virtualmachine。
使用azure_rm_virtualmachine，我们注册事实并将它们添加到变量中：
- name: Azure Facts
azure_rm_virtualmachine:
name: myvm
resource_group: myrsg
register: myvm
然后，使用带有azure_rm_deployment 的 JSON 模板部署 VM，但保留 VM 的重要值：
注意：变量仅供参考，正确使用它们以保持清洁和可管理：
- name: Create Azure VM from ARM template with public IP
azure_rm_deployment:
state: present
deployment_name: mydeployment
location: mylocation
resource_group_name: myresorcegroup
wait_for_deployment_completion: yes
template: " lookup('template', 'azure.json') "
parameters:
tags:
value: " vmtags "
adminUsername:
value: " myvm.ansible_facts.azure_vm.properties.osProfile.adminUsername "
adminPassword:
value: mypassword
imageName:
value: " myvm.ansible_facts.azure_vm.properties.storageProfile.imageReference.id | basename "
imageResourceGroup:
value: myimagesrsg
dnsLabelPrefix:
value: " myvm.ansible_facts.azure_vm.properties.networkProfile.networkInterfaces[0].properties.ipConfigurations[0].properties.publicIPAddress.properties.dnsSettings.domainNameLabel "
vmName:
value: myvm
ComputerName:
value: " myvm.ansible_facts.azure_vm.properties.osProfile.computerName "
vmResourceGroup:
value: myrsg
nicName:
value: " myvm.ansible_facts.azure_vm.properties.networkProfile.networkInterfaces[0].name "
virtualNetworkName:
value: "myvm.ansible_facts.azure_vm.properties.networkProfile.networkInterfaces[0].properties.ipConfigurations[0].properties.subnet.id.split('/')[-3] "
publicIPAddressName:
value: " myvm.ansible_facts.azure_vm.properties.networkProfile.networkInterfaces[0].properties.ipConfigurations[0].properties.publicIPAddress.name "
subnetName:
value: " myvm.ansible_facts.azure_vm.properties.networkProfile.networkInterfaces[0].properties.ipConfigurations[0].properties.subnet.id | basename "
vmSize:
value: " myvm.ansible_facts.azure_vm.properties.hardwareProfile.vmSize "
storageAccountType:
value: " myvm.ansible_facts.azure_vm.properties.storageProfile.osDisk.managedDisk.storageAccountType "
密码不会改变，VM 名称和资源组已经知道，标签是这样的字典：
vars:
vmtags:
MyFirstDay: "Saturday"
Env: "dev"
JSON 模板呢？
JSON 是标准 Azure 模板，但将标签添加为 对象：

基本上这是第一种方法，命名变量、应用方式等将以更优化的方式发生变化。我会在改进时更新它。
