< p > Azure is Microsoft's cloud offering. Each possible resource that can be deployed in Azure has a location it's deployed in, such as " East US" or " Italy." While some resources can be deployed in all locations, other resources have location constraints.</ p >
< p > It's common, when deploying, to have a whole ecosystem of resources that will work together. However, this introduces a problem: which locations work for all resources in a deployment?</ p >
< p > Let's dig in. (Want just the outcome? Check the < a href = "#summary" > summary</ a > .)</ p >
< h3 id = "bicep" > bicep</ h3 >
< p >< a href = "https://learn.microsoft.com/azure/azure-resource-manager/bicep/overview?tabs=bicep" > Bicep</ a > is a language for describing Azure resources. A Bicep file sets out a series of resources with preset or parameterized properties in order to deploy said resources.</ p >
< p > A minimal Bicep file that creates a resource group might look like this:</ p >
< pre class = "language-bicep" >< code class = "language-bicep" >< span class = "token keyword" > param</ span > resourceGroupName < span class = "token datatype class-name" > string</ span > < span class = "token operator" > =</ span > < span class = "token string" > 'myResourceGroup'</ span >
< span class = "token keyword" > param</ span > location < span class = "token datatype class-name" > string</ span > < span class = "token operator" > =</ span > "westus2"
< span class = "token keyword" > resource</ span > resourceGroup < span class = "token string" > 'Microsoft.Resources/resourceGroups@2022-09-01'</ span > < span class = "token operator" > =</ span > < span class = "token punctuation" > {</ span >
< span class = "token property" > name</ span >< span class = "token operator" > :</ span > resourceGroupName
< span class = "token property" > location</ span >< span class = "token operator" > :</ span > location
< span class = "token punctuation" > }</ span ></ code ></ pre >
< p > This is easy to start parsing - I can use < code > grep</ code > to find that < code > Microsoft.Resources/resourceGroups@2022-09-01</ code > string and go from there.</ p >
< h4 id = "nesting" > nesting</ h4 >
< p > However, minimal is uncommon. As stated above, deployments of multiple resources are much more common.</ p >
< p > When working with large deployments, certain resources may be needed more than once. You can repeat your earlier storage account declaration, or, instead, you can template out how to deploy a storage account with given parameters, then reuse that template. This is called a < code > module</ code > , and it's fundamental to organizing Bicep files.</ p >
< p > Let's say this is our file structure. Ignore the lack of parameter files or READMEs, this is just an example.</ p >
