Azure ARM Template DependentOn FileShare - azure

Question

I need to create via ARM template storage account --> File share --> Container with mounted fileshare.
The dependency is:
file share depends on storage account
container depends on file share
How to get ReferenceId of Fileshare?
I have the following code:
{
"$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
"contentVersion": "1.0.0.0",
"parameters": {
"storageAccountType": {
"type": "string",
"defaultValue": "Standard_LRS",
"allowedValues": [
"Standard_LRS",
"Standard_GRS"
],
"metadata": {
"description": "Storage account type (SKU)"
}
},
"fileShareName": {
"type": "string",
"minLength": 3,
"maxLength": 63,
"defaultValue": "sftp",
"metadata": {
"description": "Name of the File Share to be created. "
}
}
},
"variables": {
"deploymentLocation": "[resourceGroup().location]",
"storageAccountName": "[concat('sftpstr', uniqueString(resourceGroup().id))]"
},
"resources": [
{
"type": "Microsoft.Storage/storageAccounts",
"name": "[variables('storageAccountName')]",
"apiVersion": "2019-06-01",
"location": "[variables('deploymentLocation')]",
"sku": {
"name": "[parameters('storageAccountType')]"
},
"kind": "StorageV2",
"properties": {
"accessTier": "Hot"
}
},
{
"type": "Microsoft.Storage/storageAccounts/fileServices/shares",
"apiVersion": "2019-06-01",
"properties": {
"accessTier": "Hot"
},
"name": "[concat(variables('storageAccountName'), '/default/', parameters('fileShareName'))]",
"dependsOn": [
"[resourceId('Microsoft.Storage/storageAccounts', variables('storageAccountName'))]"
]
},
{
"type": "Microsoft.ContainerInstance/containerGroups",
"name": "sftp-container-group",
"apiVersion": "2018-04-01",
"dependsOn": [
"[resourceId('Microsoft.Storage/storageAccounts/fileServices/shares', ????? )]" //how to get reference to specific Fileshare??? I've tried > [concat(variables('storageAccountName'), '/default/', parameters('fileShareName'))] but it didn't work
],
"properties": {
.......
}
}
]
}
and I don't know how to set dependency on Fileshare:
"dependsOn": [
"[resourceId('Microsoft.Storage/storageAccounts/fileServices/shares', ????? )]" //how to get reference to specific Fileshare???
],
I've tried [concat(variables('storageAccountName'), '/default/', parameters('fileShareName'))] but it didn't work.
Any idea?
Thank you

Answer 1

Use following format:
"dependsOn": [
"[resourceId('Microsoft.Storage/storageAccounts/fileServices/shares', variables('storageAccountName') , 'default', parameters('fileShareName') )]"
],

Answer 2

You could create two separate resources Microsoft.Storage/storageAccounts/fileServices and Microsoft.Storage/storageAccounts/fileServices/shares and try to set dependency on Fileshare like this:
"dependsOn": [
"[resourceId('Microsoft.Storage/storageAccounts/fileServices/shares', variables('storageAccountName'), 'default', parameters('fileShareName') )]"
],
Alternatively, It's recommended to creates a storage account and a file share via azure-CLI in a Container Instance and refer to this quickstart template.
"variables": {
"image": "microsoft/azure-cli",
"cpuCores": "1.0",
"memoryInGb": "1.5",
"containerGroupName": "createshare-containerinstance",
"containerName": "createshare"
},
"resources": [
{
"type": "Microsoft.Storage/storageAccounts",
"name": "[parameters('storageAccountName')]",
"apiVersion": "2019-06-01",
"location": "[parameters('location')]",
"sku": {
"name": "[parameters('storageAccountType')]"
},
"kind": "StorageV2"
},
{
"name": "[variables('containerGroupName')]",
"type": "Microsoft.ContainerInstance/containerGroups",
"apiVersion": "2019-12-01",
"location": "[parameters('containerInstanceLocation')]",
"dependsOn": [
"[resourceId('Microsoft.Storage/storageAccounts/', parameters('storageAccountName'))]"
],
"properties": {
"containers": [
{
"name": "[variables('containerName')]",
"properties": {
"image": "[variables('image')]",
"command": [
"az",
"storage",
"share",
"create",
"--name",
"[parameters('fileShareName')]"
],
"environmentVariables": [
{
"name": "AZURE_STORAGE_KEY",
"value": "[listKeys(parameters('storageAccountName'),'2019-06-01').keys[0].value]"
},
{
"name": "AZURE_STORAGE_ACCOUNT",
"value": "[parameters('storageAccountName')]"
}
],
"resources": {
"requests": {
"cpu": "[variables('cpuCores')]",
"memoryInGb": "[variables('memoryInGb')]"
}
}
}
}
],
"restartPolicy": "OnFailure",
"osType": "Linux"
}
}
]

I found a couple of things that made it work for me:
ACI has to depend on the share otherwise it gets created ahead of volume sometimes
"dependsOn": ["resourceId('Microsoft.Storage/storageAccounts/fileServices/shares',variables('storage-account-name'), 'default', variables('file-share-name'))]"]
For some reason, the share wasn't working as a child resource so I had to make it a full resource
{
"type": "Microsoft.Storage/storageAccounts/fileServices/shares",
"apiVersion": "2021-04-01",
"name": "[concat(variables('storage-account-name'),'/default/',variables('nginx-share-name'))]",
"properties":{
"enabledProtocols": "SMB"
},
"dependsOn": [
"[resourceId('Microsoft.Storage/storageAccounts', variables('storage-account-name'))]"
]
}
Also, I had to pay attention to default part of the resource ID
"name": "[concat(variables('storage-account-name'),'/default/',variables('nginx-share-name'))]"
And finally, ACI wasn't connecting properly unless I explicitly enabled SMB as a protocol
"properties":{
"enabledProtocols": "SMB"
}
This is a template I'm using to spin up NGINX in Azure Container instances with an Azure File Share as a mounted volume.
