+> 
+> **Required?** ❌

+> #### Option: --node
+> 
+> **Required?** ❌
+> 
+> Set which version of Node to install in your container. Is ignored if the `--disable-node` flag is
+> passed, or if Node is disabled in your projects `spinner.yaml` file. Equivalent to setting `options.environment.node.version = x`
+> in your projects Spinner config.
+
+> #### Option: --disable-node
+> 
+> **Required?** ❌
+>

+> unit tests or something.
