Described embodiments automatically and dynamically generate and update resource templates for deployable resources, utilizing composable parts that may be dynamically replaced. Common portions of the templates may be easily defined once and reused multiple times, reducing risk of error and ensuring stability and cross-resource compatibility. Each dynamic template may have replaceable parts, as well as replaceable parameters and values within the replaceable parts, as well as in common portions of the template. The replacement properties and values may be determined at runtime or during deployment, ensuring that configurations are always current.
