Using Flyway

Flyway is a popular database migration tool that is commonly used in JVM environments.

Quarkus provides first class support for using Flyway as will be explained in this guide.

Setting up support for Flyway

As shown in the Developing with Flyway section, to start using Flyway with your project, you just need to:

add your migrations to the src/main/resources/db/migration folder as you usually do with Flyway
activate the migrate-at-start option to migrate the schema automatically or inject the Flyway object and run your migration as you normally do

In your build file, add the following dependencies:

the Flyway extension
your JDBC driver extension (quarkus-jdbc-postgresql, quarkus-jdbc-h2, quarkus-jdbc-mariadb, …)
unless you’re using in-memory or file databases (such as H2 or SQLite), you need to add a flyway module dependency corresponding to the database you’re using. (for more details)

Flyway support relies on the Quarkus datasource config. It can be customized for the default datasource as well as for every named datasource. First, you need to add the datasource config to the application.properties file in order to allow Flyway to manage the schema. Also, you can customize the Flyway behaviour by using the following properties:

Propiedad de configuración fijada en tiempo de compilación - Todas las demás propiedades de configuración son anulables en tiempo de ejecución

Configuration property	Tipo	Por defecto
`quarkus.flyway.enabled` Whether Flyway is enabled during the build. If Flyway is disabled, the Flyway beans won’t be created and Flyway won’t be usable. Environment variable: `QUARKUS_FLYWAY_ENABLED` Show more	boolean	`true`

Unprefixed locations or locations starting with classpath: point to a package on the classpath and may contain both SQL and Java-based migrations. Locations starting with filesystem: point to a directory on the filesystem, may only contain SQL migrations and are only scanned recursively down non-hidden directories. Environment variable: `QUARKUS_FLYWAY_LOCATIONS` Show more	list of string	`db/migration`
`quarkus.flyway.callbacks` Comma-separated list of fully qualified class names of Callback implementations to use to hook into the Flyway lifecycle.

About the Duration format

To write duration values, use the standard java.time.Duration format. See the Duration#parse() Java API documentation for more information.

You can also use a simplified format, starting with a number:

If the value is only a number, it represents time in seconds.
If the value is a number followed by ms, it represents time in milliseconds.

In other cases, the simplified format is translated to the java.time.Duration format for parsing:

If the value is a number followed by h, m, or s, it is prefixed with PT.
If the value is a number followed by d, it is prefixed with P.

Developing with Flyway

El siguiente es un ejemplo para el archivo application.properties:

# configure your datasource
quarkus.datasource.db-kind=postgresql
quarkus.datasource.username=sarah
quarkus.datasource.password=connor
quarkus.datasource.jdbc.url=jdbc:postgresql://localhost:5432/mydatabase

# Run Flyway migrations automatically
quarkus.flyway.migrate-at-start=true

# More Flyway configuration options
# quarkus.flyway.baseline-on-migrate=true
# quarkus.flyway.baseline-version=1.0.0
# quarkus.flyway.baseline-description=Initial version
# quarkus.flyway.connect-retries=10
# quarkus.flyway.schemas=TEST_SCHEMA
# quarkus.flyway.table=flyway_quarkus_history
# quarkus.flyway.locations=db/location1,db/location2
# quarkus.flyway.sql-migration-prefix=X
# quarkus.flyway.repeatable-sql-migration-prefix=K

Add a SQL migration to the default folder following the Flyway naming conventions: src/main/resources/db/migration/V1.0.0__Quarkus.sql

CREATE TABLE quarkus
(
  id   INT,
  name VARCHAR(20)
);
INSERT INTO quarkus(id, name)
VALUES (1, 'QUARKED');

Now you can start your application and Quarkus will run the Flyway’s migrate method according to your config.

With quarkus.flyway.migrate-at-start=true, as in the example above, Quarkus will execute the Flyway migration as part of the application startup.

@ApplicationScoped
public class MigrationService {
    // You can Inject the object if you want to use it manually
    @Inject
    Flyway flyway; (1)

    public void checkMigration() {
        // This will print 1.0.0
        System.out.println(flyway.info().current().getVersion().toString());
    }
}

1	Inject the Flyway object if you want to use it directly

In dev mode Quarkus will automatically restart the application if any of the existing migration scripts get modified. If you want to take advantage of this while developing and testing new migration scripts, you will want to set %dev.quarkus.flyway.clean-at-start=true, so that Flyway actually runs the modified migration.

Repairing the Flyway schema history table

There are different scenarios which may require repairing the Flyway schema history table. One such scenario is when a migration fails in a database which doesn’t support transactional DDL statements.

In such situations the Flyway repair command comes in handy. In Quarkus this can either be executed automatically before the migration by setting quarkus.flyway.repair-at-start=true or manually by injecting the Flyway object and calling Flyway#repair().

Multiple datasources

Flyway can be configured for multiple datasources. The Flyway properties are prefixed exactly the same way as the named datasources, for example:

quarkus.datasource.db-kind=h2
quarkus.datasource.username=username-default
quarkus.datasource.jdbc.url=jdbc:h2:tcp://localhost/mem:default
quarkus.datasource.jdbc.max-size=13

quarkus.datasource.users.db-kind=h2
quarkus.datasource.users.username=username1
quarkus.datasource.users.jdbc.url=jdbc:h2:tcp://localhost/mem:users
quarkus.datasource.users.jdbc.max-size=11

quarkus.datasource.inventory.db-kind=h2
quarkus.datasource.inventory.username=username2
quarkus.datasource.inventory.jdbc.url=jdbc:h2:tcp://localhost/mem:inventory
quarkus.datasource.inventory.jdbc.max-size=12

# Flyway configuration for the default datasource
quarkus.flyway.schemas=DEFAULT_TEST_SCHEMA
quarkus.flyway.locations=db/default/location1,db/default/location2
quarkus.flyway.migrate-at-start=true

# Flyway configuration for the "users" datasource
quarkus.flyway.users.schemas=USERS_TEST_SCHEMA
quarkus.flyway.users.locations=db/users/location1,db/users/location2
quarkus.flyway.users.migrate-at-start=true

# Flyway configuration for the "inventory" datasource
quarkus.flyway.inventory.schemas=INVENTORY_TEST_SCHEMA
quarkus.flyway.inventory.locations=db/inventory/location1,db/inventory/location2
quarkus.flyway.inventory.migrate-at-start=true

Notice there’s an extra bit in the key. The syntax is as follows: quarkus.flyway.[optional name.][datasource property].

Without configuration, Flyway is set up for every datasource using the default settings.

Customizing Flyway

In cases where Flyway needs to be configured in addition to the configuration options that Quarkus provides, the io.quarkus.flyway.FlywayConfigurationCustomizer class comes in handy.

To customize Flyway for the default datasource, simply add a bean like so:

@Singleton
public static class MyCustomizer implements FlywayConfigurationCustomizer {

    @Override
    public void customize(FluentConfiguration configuration) {
        // do something with configuration
    }
}

When named datasources are used, the @FlywayDataSource annotation can be used to specify the datasource to which the customizer applies. For example, if there are multiple datasources one of which is called users and customization of Flyway is needed for only that datasource, then the following code can be used:

@Singleton
@FlywayDataSource("users")
public static class UsersCustomizer implements FlywayConfigurationCustomizer {

    @Override
    public void customize(FluentConfiguration configuration) {
        // do something with configuration
    }
}

Using the Flyway object

In case you are interested in using the Flyway object directly, you can inject it as follows:

@ApplicationScoped
public class MigrationService {
    // You can Inject the object if you want to use it manually
    @Inject
    Flyway flyway; (1)

    @Inject
    @FlywayDataSource("inventory") (2)
    Flyway flywayForInventory;

    @Inject
    @Named("flyway_users") (3)
    Flyway flywayForUsers;

    public void checkMigration() {
        // Use the flyway instance manually
        flyway.clean(); (4)
        flyway.migrate();
        // This will print 1.0.0
        System.out.println(flyway.info().current().getVersion().toString());
    }
}

1	Inject the Flyway object if you want to use it directly
2	Inject Flyway for named datasources using the Quarkus `FlywayDataSource` qualifier
3	Inject Flyway for named datasources
4	Use the Flyway instance directly

Flyway and Hibernate ORM

When using Flyway together with Hibernate ORM, you can use the Dev UI to generate the initial schema creation script.

You can find more information about this feature in the Hibernate ORM guide.

Flyway and Reactive datasources

Flyway internally relies on a JDBC datasource, whereas reactive use cases will rely on reactive SQL clients, either directly or through Hibernate Reactive. This is not a problem in Quarkus, because a single configured datasource can be made available both through reactive clients and JDBC.

To use Flyway on a datasource you otherwise access reactively, simply make sure to configure that datasource both as JDBC and reactive. This involves in particular adding dependencies to Quarkus extensions for both the JDBC driver and the reactive client, for instance quarkus-jdbc-postgresql and quarkus-reactive-pg-client.

Flyway on Kubernetes

Sometimes, it’s helpful not to execute Flyway initialization on each application startup. One such example is when deploying

on Kubernetes, where it doesn’t make sense to execute Flyway on every single replica. Instead it’s desirable to execute it once and then start the actual application without Flyway. To support this use case, when generating manifests for Kubernetes the generated manifests contain a Kubernetes initialization Job for Flyway. The Job performs initialization and the actual Pod, will starts once the Job is successfully completed.

Disabling

The feature is enabled by default and can be globally disabled, using:

quarkus.kubernetes.init-task-defaults.enabled=false

or on OpenShift:

quarkus.openshift.init-task-defaults.enabled=false

Using a custom image that controls waiting for the Job

To change the wait-for image which by default is groundnuty/k8s-wait-for:no-root-v1.7 you can use:

quarkus.kubernetes.init-task-defaults.wait-for-container.image=my/wait-for-image:1.0

or on OpenShift:

quarkus.openshift.init-task-defaults.wait-for-container.image=my/wait-for-image:1.0

Note: In this context globally means for all extensions that support init task externalization.
