Official Flyway Community Docker images

This is the official repository for Flyway Command-line images.

The Flyway Community images are available in flyway/flyway on Dockerhub.

Supported Tags

The following tags are officially supported:

• 9.1.4, 9.1, 9, latest (Dockerfile)
• 9.1.4-alpine, 9.1-alpine, 9-alpine, latest-alpine (alpine/Dockerfile)
• 9.1.4-azure, 9.1-azure, 9-azure, latest-azure (azure/Dockerfile)

The flyway/flyway:*-azure images only support alpine versions.

Supported Volumes

To make it easy to run Flyway the way you want to, the following volumes are supported:

Getting started

The easiest way to get started is simply to test the default image by running

docker run --rm flyway/flyway

This will give you Flyway Command-line's usage instructions.

To do anything useful however, you must pass the arguments that you need to the image. For example:

docker run --rm flyway/flyway -url=jdbc:h2:mem:test -user=sa info

Note that the syntax for flyway/flyway:*-azure is slightly different in order to be compatible with Azure Pipelines agent job requirements. As it does not define an entrypoint, you need to explicitly add the flyway command. For example:

docker run --rm flyway/flyway:latest-azure flyway

Adding SQL files

To add your own SQL files, place them in a directory and mount it as the flyway/sql volume.

Example

Create a new directory and add a file named V1__Initial.sql with following contents:

CREATE TABLE MyTable (
    MyColumn VARCHAR(100) NOT NULL
);

Now run the image with the volume mapped:

docker run --rm -v /absolute/path/to/my/sqldir:/flyway/sql flyway/flyway -url=jdbc:h2:mem:test -user=sa migrate

Adding a config file

If you prefer to store those arguments in a config file you can also do so using the flyway/conf volume.

Example

Create a file named flyway.conf with the following contents:

flyway.url=jdbc:h2:mem:test
flyway.user=sa

Now run the image with that volume mapped as well:

docker run --rm -v /absolute/path/to/my/sqldir:/flyway/sql -v /absolute/path/to/my/confdir:/flyway/conf flyway/flyway migrate

Adding a JDBC driver

If your database driver is not shipped by default (you can check the official documentation here to see if it is), or if you want to use a different or newer driver than the one included you can do so using the flyway/drivers volume.

Example

Create a directory and drop for example the MySQL JDBC driver in there.

You can now let Flyway make use of it my mapping that volume as well:

docker run --rm -v /absolute/path/to/my/sqldir:/flyway/sql -v /absolute/path/to/my/confdir:/flyway/conf -v /absolute/path/to/my/driverdir:/flyway/drivers flyway/flyway migrate

Adding Java-based migrations and callbacks

To pass in Java-based migrations and callbacks you can use the flyway/jars volume.

Example

Create a directory and drop for a jar with your Java-based migrations in there.

You can now let Flyway make use of it my mapping that volume as well:

docker run --rm -v /absolute/path/to/my/sqldir:/flyway/sql -v /absolute/path/to/my/confdir:/flyway/conf -v /absolute/path/to/my/jardir:/flyway/jars flyway/flyway migrate

Docker Compose

To run both Flyway and the database that will be migrated in containers, you can use a docker-compose.yml file that starts and links both containers.

Example

version: '3'
services:
  flyway:
    image: flyway/flyway
    command: -url=jdbc:mysql://db -schemas=myschema -user=root -password=P@ssw0rd -connectRetries=60 migrate
    volumes:
      - .:/flyway/sql
    depends_on:
      - db
  db:
    image: mysql
    environment:
      - MYSQL_ROOT_PASSWORD=P@ssw0rd
    command: --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci
    ports:
      - 3306:3306

Run docker-compose up, this will start both Flyway and MySQL. Flyway will automatically wait for up to one minute for MySQL to be initialized before it begins to migrate the database.
