我有一个ARM模板,我设置了一个负载均衡器,我想通过向LB添加规则和探测来添加一些端口.
这是我到目前为止的模板:
{

}
}
}
],
"backendAddressPools": [
{

}
],
"loadBalancingRules": [
{

},

}
}
},
{

"properties": {

"id": "[parameters('loadBalancers_LB_dev_id_9')]"
},
"frontendPort": 81,

},

}
}
},
{

"properties": {

},
"frontendPort": 82,
"backendPort": 82,
"enableFloatingIP": false,
"idleTimeoutInMinutes": 5,
"protocol": "Tcp",
"loadDistribution": "Default",
"backendAddressPool": {
"id": "[parameters('loadBalancers_LB_dev_id_13')]"
},
"probe": {
"id": "[parameters('loadBalancers_LB_dev_id_14')]"
}
}
}
],
"probes": [
{
"name": "AppPortProbe1",
"properties": {
"protocol": "Tcp",
"port": 80,
"intervalInSeconds": 5,
"numberOfProbes": 2
}
},
{
"name": "AppPortProbe2",
"properties": {
"protocol": "Tcp",
"port": 81,
"intervalInSeconds": 5,
"numberOfProbes": 2
}
},
{
"name": "AppPortProbe3",
"properties": {
"protocol": "Tcp",
"port": 82,
"intervalInSeconds": 5,
"numberOfProbes": 2
}
}
],
"inboundNatRules": [],
"outboundNatRules": [],
"inboundNatPools": []
},
"resources": [],
"dependsOn": [
"[resourceId('Microsoft.Network/publicIPAddresses', parameters('publicIPAddresses_lbipdev_1_name'))]"
]
},
(省略一些细节)
我想要做的是拥有一个我想要创建规则和探测器的端口号数组,并循环遍历这些端口号,而不是明确地必须将每个规则和探测作为资源的属性进行编写.
基本上我想在我的模板中有一个参数或变量,如下所示:
"ports": [ 80, 81, 82, ...]
并且我可以循环这类似于:https://docs.microsoft.com/en-us/azure/azure-resource-manager/resource-group-create-multiple.
的确你可以!复制适用于属性!
像这样创建一个参数或变量(这个例子将使用参数数组):
"lbRules": {
"type": "array",
"defaultValue": [
{
"name": "httpPort",
"frontendPort": "80",
"backendPort": "80",
"protocol": "tcp"
},
{
"name": "customAppPort",
"frontendPort": "8080",
"backendPort": "8888",
"protocol": "tcp"
},
{
"name": "httpsPort",
"frontendPort": "443",
"backendPort": "443",
"protocol": "tcp"
}
]
}
在Loadbalancer资源中使用此参数,使用这样的副本,这将创建您在参数数组中定义的许多探针和规则:
{
"apiVersion": "[variables('lbApiVersion')]",
"type": "Microsoft.Network/loadBalancers",
"name": "[parameters('myLoadBalancer')]",
"location": "[parameters('computeLocation')]",
"dependsOn": [
"[concat('Microsoft.Network/publicIPAddresses/',concat(parameters('lbIPName'),'-','0'))]"
],
"properties": {
"frontendIPConfigurations": [
{
"name": "LoadBalancerIPConfig",
"properties": {
"publicIPAddress": {
"id": "[resourceId('Microsoft.Network/publicIPAddresses',concat(parameters('lbIPName'),'-','0'))]"
}
}
}
],
"backendAddressPools": [
{
"name": "LoadBalancerBEAddressPool",
"properties": {}
}
],
"copy": [
{
"name": "probes",
"count": "[length(parameters('lbRules'))]",
"input": {
"name": "[concat(parameters('lbRules')[copyIndex('probes')].name,'Probe')]",
"properties": {
"intervalInSeconds": 5,
"numberOfProbes": 2,
"port": "[parameters('lbRules')[copyIndex('probes')].backendPort]",
"protocol": "[parameters('lbRules')[copyIndex('probes')].protocol]"
}
}
},
{
"name": "loadBalancingRules",
"count": "[length(parameters('lbRules'))]",
"input": {
"name": "[parameters('lbRules')[copyIndex('loadBalancingRules')].name]",
"properties": {
"frontendIPConfiguration": {
"id": "[concat(resourceId('Microsoft.Network/loadBalancers', parameters('myLoadBalancer')),'/frontendIPConfigurations/LoadBalancerIPConfig')]"
},
"frontendport": "[parameters('lbRules')[copyIndex('loadBalancingRules')].frontendport]",
"backendport": "[parameters('lbRules')[copyIndex('loadBalancingRules')].backendport]",
"enableFloatingIP": false,
"idleTimeoutInMinutes": "5",
"protocol": "[parameters('lbRules')[copyIndex('loadBalancingRules')].protocol]",
"backendAddressPool": {
"id": "[concat(resourceId('Microsoft.Network/loadBalancers', parameters('myLoadBalancer')),'/backendAddressPools/LoadBalancerBEAddressPool')]"
},
"probe": {
"id": "[concat(variables('lbID0'),'/probes/', parameters('lbRules')[copyIndex('loadBalancingRules')].name,'Probe')]"
}
}
}
}
],
"inboundNatPools": []
},
}
}

您只能将复制对象应用于顶级资源。
您不能将其应用于资源类型的属性或子资源。
"resources": [
{
"type": "{provider-namespace-and-type}",
"name": "parentResource",
"copy": {
/* yes, copy can be applied here */
},
"properties": {
"exampleProperty": {
/* no, copy cannot be applied here */
}
},
"resources": [
{
"type": "{provider-type}",
"name": "childResource",
/* copy can be applied if resource is promoted to top level */
}
]
}
]
报价来源：在Azure资源管理器模板中部署资源的多个实例
仅当将复制对象应用于顶级资源（在您的情况下为“ Microsoft.Network/loadBalancers”）时，才可以在ARM模板中循环属性，但是也会创建该资源的多个副本。
如果这不是您想要实现的，我建议您保留现有方式，直到将来ARM模板支持将对象复制到资源类型的属性上为止。
