模板结构
{
"$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
"contentVersion": "1.0.0.0",
"parameters": { },
"variables": { },
"resources": [ ],
"outputs": { }
}
参数
"parameters": {
"storageAccountName": {
"type": "string",
"minLength": 3,
"maxLength": 24
},
"environment": {
"type": "string",
"defaultValue": "dev",
"allowedValues": ["dev", "staging", "prod"]
},
"adminPassword": {
"type": "securestring"
}
}
变量与函数
"variables": {
"storageAccountName": "[toLower(concat('storage', uniqueString(resourceGroup().id)))]",
"location": "[resourceGroup().location]",
"isProd": "[equals(parameters('environment'), 'prod')]",
"vmSize": "[if(variables('isProd'), 'Standard_D4s_v3', 'Standard_B2s')]"
}
// 常用 ARM 函数：
// concat(s1, s2) - 字符串拼接
// uniqueString(str) - 确定性哈希
// resourceId(type, name) - 获取资源 ID
// reference(id) - 获取资源属性
