The latest release of Truss, version 0.1.5, introduces a live reload mechanic to improve developer velocity when working with Docker.
Docker is great because it makes your development environment nearly identical to your production environment. But that comes at the expense of rebuilding your environment when you make changes to your Truss. With live reload, you can now make changes to your model code and keep the same Docker container running, which can save several minutes every time you change your code.
To enable this feature, install the latest version of Truss and set live_reload = True in your Truss config file.
