I am trying to implement a linked template where a child template depends on a resource in the parent template. Is that possible?

@mumian - I think using the symbolic name shown below sends the wrong message:

resource provide_unique_name 'Microsoft.Storage/storageAccounts@2019-06-01' = {

Shouldn't provide_unique_name be just a simple name for the resource like stg ? If users try to reference the storage account somewhere else in the template they would have use the long name.

@tfitzmac, could you add expected output examples for crossresourcegroupproperties.json please?

Either here or here.

Thanks

There are important files that Microsoft projects should all have that are not present in this repository. A pull request has been opened to add the missing file(s). When the pr is merged this issue will be closed automatically.

Microsoft teams can learn more about this effort and share feedback within the open source guidance available internally.

@mumian - a resource deployed in a template shouldn't use the reference function to get the properties.

I see:
output storageEndpoint object = reference(storageAccountName).primaryEndpoints

It should be more like:
output storageEndpoint object = stg.primaryEndpoints

Visual studio flags this syntax as incorrect

uri(deployment().properties.templateLink.uri

I'm unclear what's wrong with it, as I have lifted it directly from the site above. There seems to be no valid way, at least from the perspective of VisualStudio to correctly leverage this function.

uri(deployment().templateLink

According to VisualStudio the above is 100% correct, but the error returned from the deployment is that templateLink is not valid, only name and properties are valid. Yet, NEITHER of those two things show up when I attempt to use them. When I put them in manually it shows me the red wavy that means it's wrong.

It's difficult to leverage some of these when I'm unable to fully understand why the provided MS examples don't work. Can we get a full breakdown of all available properties for all functions in the documentation please?

https://github.com/Azure/azure-docs-json-samples/tree/master/deployment-script references a non-existing page: https://docs.microsoft.com/azure/azure-resource-manager/deployment-script-in-template (I couldn't find the proper link it should reference, in fact I couldn't find any mention of this feature except in some non-MS blog about Ignite 2019).

How can I use these parameters inside a string?

For example I have the following line in my template

"path": "/v2/datasets/@{encodeURIComponent(encodeURIComponent(parameters('sql_2_server')))},@{encodeURIComponent(encodeURIComponent(parameters('sql_2_database')))}/query/sql"

As I have tried, I want to pass two parameters sql_2_server and sql_2_database inside this.

What's the syntax for this??

When using split to create an array from an empty string, the result is an array with one string that has no value. While it's possible to work around this (below), it was unexpected behaviour - maybe I'm wrong, but personally I would have expected an empty array with a length of 0.

It would be helpful if this behaviour was mentioned in the documentation.

Workaround...

"variables": {
    "containers": "[if(equals(length(parameters('containersString')), 0), json('[]'), split(parameters('containersString'), ','))]"
},

Not an issue, but it would be nice to have generation of dynamic names output.
Someting like this

  "outputs": {
    "networks": {
      "type": "array",
      "copy": {
        "count": "[length(variables('networks'))]",
        "input": "[variables('networks')[copyIndex()]]",
        "name": "[concat('some', variables('networks')[copyIndex()])]"
      }
    }
  }

So, this code just expand array, and 'networks' property is not put to the output

I imported the Azure Firewall OMS template but it seems the strings changed values and now
Unique Source IPS show up empty in addition to Denied Application URLS.

Can anybody update it? I tried but coudn't figure out the syntax to the query.

As a developer using ARM templates to deploy a resource group I would like an optional tags parameter so that I can tag the resource group if required.

@mumian - we shouldn't use the concat function in bicep.

I see:
var storageAccountName_var = concat(projectName, uniqueString(resourceGroup().id))

Which I believe can be:
var storageAccountName_var = '${projectName}${uniqueString(resourceGroup().id)}'

As per https://github.com/Azure/azure-docs-json-samples/blob/master/azure-resource-manager/parameterswithfunctions.json, I tried using functions to set default value to parameters which is failing for me.
On setting a parameter as
..."virtualMachineName": { "defaultValue": "[concat('vm', uniqueString(resourceGroup().id))]", "type": "string" }, ...
default value is not as expected:
