Output CosmosDB String

Question

I'm trying to call out Connection Strings from the CosmosDB in to KeyVault Secret. I keep getting this error but am unsure what the fix is.

There is nothing online what suggests on how to call out the CosmosDB

The output code is

output "connection_strings" {
value = azurerm_cosmosdb_account.cosmos_db.connection_strings
}

and on key vault resource is setout as this

resource "azurerm_key_vault_secret" "test" {
name = "Tst"
value = module.cosmosDB.connection_strings
key_vault_id = module.kv-secrets.id
}

The error that I get in the CLI is module.cosmosDB.connection_strings is list of string with 4 elements

Answer 1

As per Terraform doc connection strings is a list:

connection_strings - A list of connection strings available for this CosmosDB account

If you want to store the connection string into a secret, you should refer to it as:

module.cosmosDB.connection_strings[0]

Answer 2

If this hasnt be resolved yet, the way we access the connection_string for cosmos

 azurerm_cosmosdb_account.cosmos_db.connection_strings.0

As you are exposing the connection_strings completely show be able to access it by adding .0 to the end
