Adventures with Bicep: Cosmos Connection Strings

I have been playing around with Azure Bicep for deploying my infrastructure to Azure.

If you are new to Bicep, please take a look at Azure/bicep: Bicep is a declarative language for describing and deploying Azure resources (github.com).

My challenge?

I want to write Cosmos connection strings to Azure Key Vault.

I am using Bicep modules.

I have a Bicep module for creating secrets in Azure Key Vault.

	param keyVaultName string
	param secretName string
	param secretValue string
	resource keyVaultSecret 'Microsoft.KeyVault/vaults/secrets@2019-09-01' = {
	name: '${keyVaultName}/${secretName}'
	properties: {
	value: secretValue
	}
	}
	output keyVaultSecretName string = keyVaultSecret.name

I am using syntax supported in ARM templates to get my connection strings, with some help of variables, which I pass in.

	param keyVaultAccountName string
	param cosmosDatabaseAccountName string
	module cosmosKeyVaultSecretPrimaryConnectionString '../modules/moduleKeyVaultSecret.bicep' = {
	name: 'cosmosKeyVaultSecretPrimaryConnectionString'
	params: {
	keyVaultName: keyVaultAccountName
	secretName: '${cosmosDatabaseAccountName}-PrimaryConnectionString'
	secretValue: listConnectionStrings(resourceId('Microsoft.DocumentDB/databaseAccounts', cosmosDatabaseAccountName), '2020-04-01').connectionStrings[0].connectionString
	}
	}
	module cosmosKeyVaultSecretSecondaryConnectionString '../modules/moduleKeyVaultSecret.bicep' = {
	name: 'cosmosKeyVaultSecretSecondaryConnectionString'
	params: {
	keyVaultName: keyVaultAccountName
	secretName: '${cosmosDatabaseAccountName}-SecondaryConnectionString'
	secretValue: listConnectionStrings(resourceId('Microsoft.DocumentDB/databaseAccounts', cosmosDatabaseAccountName), '2020-04-01').connectionStrings[1].connectionString
	}
	}

I search for this frequently, for some reason, just cannot remember it, so I record it here, more for me, but hopefully it helps another colleague out on their journey with Bicep.

Thanks and God bless!
