This is the repository for Flyway Command-line⁠ Open Source images.

For the officially certified Redgate Flyway Docker images, use Redgate/Flyway on Dockerhub, which works across the complete range of Flyway editions, including Community, Teams and Enterprise.

Redgate/Flyway also provides compatibility with Flyway Pipelines. Flyway Pipelines will help you gain centralized visibility of the state of your database deployments across projects so you can see what has been deployed, when and where for easy tracking.

To make it easy to run Flyway the way you want to, you can use the following folders in your Flyway project

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:sqlite:dev.db 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

To add your own SQL files, place them in a directory, mount it and point flyway at it using the workingDirectory parameter.

Create a new /sql directory in your project folder 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/project_folder:/flyway/project flyway/flyway -url=jdbc:sqlite:dev.db -workingDirectory="project" migrate

If you prefer to store arguments in a config file you can put that in your project folder.

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

[environments.development]
url = "jdbc:sqlite:/flyway/project/dev.db"
user= "admin"
password = "password1"

[flyway]
environment = "development"

Now run the image with that volume mapped as well:

docker run --rm -v /absolute/path/to/my/project_folder:/flyway/project flyway/flyway migrate -workingDirectory="project"

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 create a drivers/ folder in your project folder.

To pass in Java-based migrations and callbacks you can use a jars/ folder in your project directory and place them in there.

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.

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.
