Specify multiple parameters file for an ARM - azure

Question

I have a solution consisting of different services I need to deploy in my Azure account:
global_params.json:
{
"$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentParameters.json#",
"contentVersion": "1.0.0.0",
"parameters": {
"globalParam1": {
"value": "v1"
},
"globalParam2": {
"value": "v2"
}
}
}
myservice_params.json:
{
"$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentParameters.json#",
"contentVersion": "1.0.0.0",
"parameters": {
"svcParam1": {
"value": "v1"
},
"svcParam2": {
"value": "v2"
},
"svcParam3": {
"value": "v3"
}
}
}
In my ARM template azuredeploy.json I need to get both groups of parameters:
{
"$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
"contentVersion": "1.0.0.0",
"parameters": {
"globalParam1": {...}
},
"globalParam2": {...}
},
"svcParam1": {...}
},
"svcParam2": {...}
},
"svcParam3": {...}
}
},
"resources": [
{
"type": "Microsoft.Storage/storageAccounts",
"apiVersion": "2020-08-01",
"name": "[parameters('storageAccountName')]",
"location": "[parameters('globalParam1')]",
"sku": {
"name": "[parameters('svcParam1')]",
"tier": "[parameters('svcParam2')]"
},
"kind": "[parameters('svcParam3')]",
"properties": {
"accessTier": "[parameters('globalParam2')]"
}
}
]
}
How do I use the Azure CLI to make sure I pass parameters merged from both parameters file? I know one parameter file can be passed as follow (see doc):
az deployment group create ... --template-file ./azuredeploy.json --parameters #myservice_params.json
But how to specify two parameters files and get them merged?

Answer 1

The CLI (nor Azure itself) support this - you would have to do the merge yourself prior to calling into Azure.
You could use defaultValues on the parameters in the template to come close to replicating.

Answer 2

Although article is few months old, I tested it by adding second parameters file using #.
So command will be:
az deployment group create -g resourceGroup --template-file template.json --parameters #parameters1.json #parameters2.json
