Azure Container Apps now supports Azure Key Vault references in application secrets. This feature is in public preview.
Azure Key Vault references enable you to source a container app’s secrets from secrets stored in Azure Key Vault. Using the container app's managed identity, the platform automatically retrieves the secret values from Azure Key Vault and injects it into your application's secrets.
Both versioned and non-versioned secrets are supported. To learn more, see Secrets in Azure Container Apps.
