gradle-dcompose-sample

This sample project demonstrates the usage of the gradle-dcompose-plugin.

It is a simple counter that uses a MongoDB server to count how many times it has been called.

See the build.gradle file for more details!

Usage

Checkout the project and run:

• ./gradlew run to start the Java app inside a docker container
• ./gradlew test to start the integration test using a MongoDB container
• ./gradlew createComposeFile to create a docker-compose.yml file that can be used for deploying the app.
• ./graldew removeContainers removeNetworks removeVolumes removeImages to clean everything up
