This is the official repository for Flyway Command-line images.
The Flyway Community images are available in flyway/flyway on Dockerhub.
The following tags are officially supported:
10.11.0
,10.11
,10
,latest
(Dockerfile)10.11.0-alpine
,10.11-alpine
,10-alpine
,latest-alpine
(alpine/Dockerfile)10.11.0-azure
,10.11-azure
,10-azure
,latest-azure
(azure/Dockerfile)
The flyway/flyway:*-azure images only support alpine versions.
To make it easy to run Flyway the way you want to, the following volumes are supported:
Volume | Usage |
---|---|
/flyway/conf |
Directory containing a flyway.conf configuration file |
/flyway/drivers |
Directory containing the JDBC driver for your database |
/flyway/sql |
The SQL files that you want Flyway to use (for SQL-based migrations) |
/flyway/jars |
The jars files that you want Flyway to use (for Java-based migrations) |
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
To add your own SQL files, place them in a directory and mount it as the flyway/sql
volume.
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
If you prefer to store those arguments in a config file you can also do so using the flyway/conf
volume.
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
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.
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
To pass in Java-based migrations and callbacks you can use the flyway/jars
volume.
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
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.
