There is a syntax highlighting error in the azurerm-vscode-tools extension when editing ARM templates. In the following block in the variables section, the opening "copy": block is underlined green indicating that it is never used and all references to the name "generatedSecurityRules" are underlined red indicating that it is not defined.

The template actually executes fine when run against the Azure API. Just come across this issues. Although its not a massive problem, it does make it hard to review and edit code.

You can also use copy with resourcesproperties in a resourceand variables. The count property specifies the number of iterations you want for the output value. The input property specifies the properties that you want to repeat. You create an array of elements constructed from the value in the input property. It can be a single property like a stringor an object with several properties.

The count can't be a negative number. Specifically, you must use:. The following example creates a variable number of storage accounts and returns an endpoint for each storage account:. Submit and view feedback for.

The following example template uses the base64ToJson function to convert a base64 value:. The following example template uses the base64ToString function to convert a base64 value:.

Combines multiple string values and returns the concatenated string, or combines multiple arrays and returns the concatenated array. This function can take any number of arguments, and can accept either strings or arrays for the parameters.

However, you can't provide both arrays and strings for parameters. Strings are only concatenated with other strings. The following example template shows how to combine two string values and return a concatenated string. The following example template shows how to combine two arrays. Checks whether an array contains a value, an object contains a key, or a string contains a substring. The string comparison is case-sensitive.

However, when testing if an object contains a key, the comparison is case-insensitive. The following example template shows how to use contains with different types:. The following example template checks whether an array, object, and string are empty. True if the last character or characters of the string match the value; otherwise, False.

The following example template shows how to use the startsWith and endsWith functions:. A string of the first character, or the type string, int, array, or object of the first element in an array. The following example template shows how to use the first function with an array and string. Use this function to format a string in your template.

It uses the same formatting options as the System. Format method in. Creates a value in the format of a globally unique identifier based on the values provided as parameters. This function is helpful when you need to create a value in the format of a globally unique identifier.

You provide parameter values that limit the scope of uniqueness for the result. You can specify whether the name is unique down to subscription, resource group, or deployment. The returned value isn't a random string, but rather the result of a hash function on the parameters. The returned value is 36 characters long. It isn't globally unique. To create a new GUID that isn't based on that hash value of the parameters, use the newGuid function.

The following example template returns results from guid:. An integer that represents the position of the item to find.

The value is zero-based. If the item isn't found, -1 is returned.Have you ever wanted to create a nested loop in an ARM template? You can use the copy element to create multiple instances of a resource by looping over an array. The workaround is to move the sub-resource to the top-level and then reference the parent resource by name.

Note, the subscription is a top-level resource now. The topic loop name has been added to the dependsOn array. As a result of the copy element, multiple topics will be created, one for each item in the topics array. Then, subscriptions for each topic will be created based on the subscriptions array.

Great article, however I wanted to let you know that it is now possible to nest copy loops in ARM templates. Like Like. You are commenting using your WordPress. You are commenting using your Google account. You are commenting using your Twitter account.

Name required.In the previous blog post, we worked with the parameter subnetName to manipulate the string to remove the 0 at the end and creating a sequential count for each additional subnet.

We used the following functions: substring, length, concat, and sub. Continuing with our simple scenario, we are building a single virtual network and create multiple sequential subnets for the deployment. Our second task is to assign each new subnet a unique address range. Here is a sample of a vNet that contains three equal subnets. To accomplish this is a template we would require a parameter for each subnet address prefix.

To give our template some flexibility, we can use the split function to extract the address prefix and get each octet. This will allow you to then increment the count on the third octet to create new subnets.

The example below will split the subnet address into an array and we will use that information to create a different subnet address of In the upcoming and final article, we will combine all that we have learned from using functions and create our deployment.

The following example template shows how to use the array function with different types. Combines multiple arrays and returns the concatenated array, or combines multiple string values and returns the concatenated string.

Example The following example template shows how to use the array function with different types.Azure Resource Manager ARM templates have a nice set of built-in functions that allow you to develop complex expressions. These expressions can help a static deployment template file become more scalable and flexible for different scenarios.

In fact it runs through the normal template validation process and still produces output variables if you have items in that section.

First you simply start with an empty deployment JSON file. Then add in the minimum number of parameters you need. Lastly, construct the expression you are debugging into an output parameter.

The reason for it to be an output parameter is so that you can see the result of your expression printed back to the screen for you. This approach saves time on templates of all sizes by not actually deploying or verifying resources. You can quickly iterate through different testing values or syntax and get faster feedback on if your template expression is actually valid. Scenario: You want a template to deploy a storage account. The name of that storage account should be constructed using multiple parameters such as a name prefix, some sort of regional suffix, etc.

This is an easy expression using the concat function and a couple input parameters. Note: There better ways to accomplish this same goal- but this way makes for a great test example. In our example we build the expression and test it as an output parameter. Like Liked by 1 person. You are commenting using your WordPress. You are commenting using your Google account.
