How to Concatenate Tags (Bicep)


To build resources in Mcirosoft Azure, I’m using a Bicep script.

I’ve created a variable that has the common tags that apply to all resources. However, when I assign this variable to a resource, I’d like to add more tags that are specific to this resource.

But I haven’t yet figured out how to accomplish it.

Solution #1

To unite objects, use the union function.

I’ve defined a parameter with common tags and merged the object with resource-specific tags in this example:

param commonTags object = {
  commonTag1: 'commonTag1'
  commonTag2: 'commonTag2'

resource storageAccount 'Microsoft.Storage/storageAccounts@2019-06-01' = {
  name: 'my storage account name'
  tags: union(commonTags, {
    storageTag1: 'storageTag1'
    storageTag2: 'storageTag2'
