A bare-bones example of a Scala backend using the Play Framework. It provides a lightweight starting point for building web applications with minimal configuration. Zerops makes deploying and running Scala apps, a breeze.
You can either click the deploy button to deploy directly on Zerops, or manually copy the import yaml to the import dialog in the Zerops app.
- Latest version of Scala & JDK running on Zerops Ubuntu Service.
- Latest version of SBT(Simple build tool) with Play web framework.
By default, the project uses the Pekko HTTP Server backend. To switch to the Netty Server backend, enable the PlayNettyServer sbt plugin in the build.sbt file.
In the build.sbt of this project, you'll find a commented line for this setting; simply uncomment it to make the switch.
For more detailed information, refer to the Play Framework documentation.
This recipe is ready for production as is, and will scale horizontally by adding more containers in case of high traffic surges. If you want to achieve the highest baseline reliability and resiliace, start with at least two containers (add minContainers: 2 in recipe YAML in the app service section, or change the minimum containers in "Automatic Scaling configuration" section of service detail).
If you want to modify your existing Scala backend to efficiently run on Zerops, there are no changes needed in the codebase on top of the standard installation, just add zerops.yml to your repository.
