如何 ARM 模板 Azure SQL 故障转移组？

Question

How can I create a Azure SQL Failover Group in a different deployment to the servers?

We use deployments within deployments to achieve concurrent deployments.

I'm trying to create 2 SQL Servers, one in UK West (primary) and one in UK South (secondary), and then create a Failover group from the Primary to Secondary.

The issue is that when creating the Failover group, I have to reference the primary server to create the FOG under. This is failing and saying that the SQL Server is not defined.

Deployment template validation failed: 'The resource 'Microsoft.Sql/servers/xxxxxx' is not defined in the template. Please see https://aka.ms/arm-template for usage details.'

Is it possible to keep the deployments separate, yet still create the FOG which references the SQL Servers? All examples I can find are using a single template/deployment which makes matters slightly more straightforward.

Just came across this same problem, and found the answer on this example:

https://github.com/Azure/azure-quickstart-templates/blob/master/101-sql-with-failover-group/azuredeploy.json

The bit you're missing is: "serverName": "[parameters('sourceSqlServerName')]",

So your full resource:

{
  "name": "[concat(parameters('sourceSqlServerName'), '/', parameters('failoverGroupName'))]",
  "type": "Microsoft.Sql/servers/failoverGroups",
  "apiVersion": "2015-05-01-preview",
  "properties": {
    "readWriteEndpoint": {
      "failoverPolicy": "Manual",
      "failoverWithDataLossGracePeriodMinutes": 60
    },
    "readOnlyEndpoint": {
      "failoverPolicy": "Disabled"
    },
    "serverName": "[parameters('sourceSqlServerName')]",
    "partnerServers": [
      {
        "id": "[variables('targetServerResourceId')]"
      }
    ],
    "databases": [
          "[variables('databaseResourceId')]"
    ]
  },
  "dependsOn": [
    "[variables('sourceServerResourceId')]",
    "[variables('targetServerResourceId')]"
  ]
}
