我们有一个ARM模板,可以通过powershell命令正确创建Linux VM:
New-AzureRmResourceGroupDeployment -TemplateFile .\template.json -TemplateParameterFile .\parameters.json -ResourceGroupName my-rg -virtualMachineName my-test-vm
我们希望利用CustomScriptForLinux扩展来添加一行/ etc / hosts
以下是template.json的相关部分:
{
"name": "[concat(parameters('virtualMachineName'),'/edithosts')]",
"type": "Microsoft.Compute/virtualMachines/extensions",
"location": "[resourceGroup().location]",
"apiVersion": "2015-06-15",
"dependsOn": [
"[concat('Microsoft.Compute/virtualMachines/', parameters('virtualMachineName'))]"
],
"properties": {
"publisher": "Microsoft.OSTCExtensions",
"type": "CustomScriptForLinux",
"typeHandlerVersion": "1.5",
"autoUpgradeMinorVersion": true,
"settings": {
"commandToExecute": "sudo echo '10.X.X.X sample.acme.com' >> /etc/hosts"
}
}
}
],
部署成功且没有错误,但/ etc / hosts文件没有新行。
/var/log/azure/Microsoft.OSTCExtensions.CustomScriptForLinux/1.5.2.2/extension.log的输出包括:
Command to execute:sudo echo '10.X.X.X sample.acme.com' >> /etc/hosts
2018/03/20 15:22:29 [Microsoft.OSTCExtensions.CustomScriptForLinux-1.5.2.2] Command is finished.
2018/03/20 15:22:29 ---stdout---
2018/03/20 15:22:29 10.X.X.X sample.acme.com >> /etc/hosts

从命令中删除'sudo'没有任何区别。
答案 0 :(得分:0)
原来你需要使用bash -c "echo '10.X.X.X sample.acme.com' >> etc/hosts"
让linux正确解析来自脚本扩展的输入
