This buildpack first deploys a Java Development Kit (JDK) into your container.
It then deploys a standalone CLI tool named Webapp Runner. Webapp Runner is based on the Apache Tomcat HTTP web server. It allows to run a WAR application on Scalingo.
The default Java JDK deployed by this buildpack depends on your stack:
- For
scalingo-22: OpenJDK 1.8 - For
scalingo-24: OpenJDK 25 - For
scalingo-26: OpenJDK 25
The default Webapp Runner deployed by this buildpack is defined in one of the inventory files of the buildpack.
This buildpack is maintained by Scalingo solely for the deployment assets and integration guidance provided in this repository and its associated documentation.
Applying Java and Webapp Runner upgrades, as well as security patches remains the responsibility of the customer by updating the corresponding environment variables and redeploying the application.
Should Scalingo discontinue maintenance of this buildpack or no longer recommend its use, a notice period of at least six months will be provided whenever feasible, except where immediate action is required due to security concerns or external constraints.
