Applying Azure tags using PowerShell to multiple Azure resources
Azure tags help us organize the Azure resources we have created in Azure data engineering projects. Tags add key-value pairs to resources, which can help us easily categorize the resources and identify them. For example, adding a tag with the key set to Environment and the value set to production for resources can help us identify all production environment resources in our tenant. You can add multiple tags to the same resource too. For example, you may have two tags with Environment and Project as keys. Environment helps identify the environment that the resource belongs to, while Project helps identify which project the resource is part of.
It is always good practice to add tags at the time of resource creation. However, in some scenarios, you may need to add tags to several resources after they have been created. In this recipe, we will use a PowerShell script to tag several resources in one go.
