如何在ARM模板中转义单引号 [英] How to escape single quote in ARM template

问题描述

鉴于AzureRM模板中的以下资源，如何编码commandToExecute部分中的单引号?

Given the following resource in an AzureRM template, how would one encode the single quote in the commandToExecute part?

{
  "type": "Microsoft.Compute/virtualMachines/extensions",
  "name": "[concat(variables('vmNameMaster'), copyIndex(), '/sethost')]",
  "apiVersion": "2015-06-15",
  "location": "[resourceGroup().location]",
  "copy": {
      "name": "extensionLoopNode",
      "count": "[variables('masterCount')]"
  },
  "dependsOn": [
      "[concat('Microsoft.Compute/virtualMachines/', variables('vmNameMaster'), copyIndex(),'/extensions/DockerExtension')]"
  ],
  "properties": {
    "publisher": "Microsoft.OSTCExtensions",
    "type": "CustomScriptForLinux",
    "typeHandlerVersion": "1.4",
    "settings": {
      "fileUris": [ ],
      "commandToExecute": "[concat('/bin/bash -c \'echo \"export DOCKER_HOST=:2375\" >> /home/', parameters('adminUsername') ,'/.profile\'')]",
      "timestamp": 123456789
    }
  }
},

推荐答案

我已经使用一个变量解决了这个问题:

I've worked around this with a variable:

"variables": {
    "singleQuote": "'",
},
...
"settings": {
    "fileUris": [],
    "commandToExecute": "[concat('/bin/bash -c ', variables('singleQuote'), 'echo \"export DOCKER_HOST=:2375\" >> /home/', parameters('adminUsername') ,'/.profile', variables('singleQuote'))]",
}

它不优雅，但可以.
