Application startup

While Dropwizard doesn't come with out-of-the-box integration for Flyway you can easily run Flyway on application startup by adding flyway-core to your pom.xml:

<dependency>
    <groupId>org.flywaydb</groupId>
    <artifactId>flyway-core</artifactId>
    <version>12.8.1</version>
</dependency>

And calling Flyway from your application class:

public class MyApplication extends Application<MyConfiguration> {
    ...

    @Override
    public void run(MyConfiguration configuration, Environment environment) {
        DataSourceFactory dataSourceFactory = configuration.getDataSourceFactory();
        Flyway flyway = new Flyway();
        flyway.setDataSource(dataSourceFactory.getUrl(), dataSourceFactory.getUser(), dataSourceFactory.getPassword());
        flyway.migrate();
        ...
    }
}

CLI add-on

Jochen Schalanda has created a great Dropwizard Add-On that adds Flyway commands to the CLI of your Dropwizard application.

The website also comes with comprehensive documentation on usage and configuration.
