The primary goal of the https://projects.spring.io/spring-data[Spring Data] project is to make it easier to build Spring-powered applications that use data access technologies. *Spring Data R2DBC* offers the popular Repository abstraction based on https://r2dbc.io[R2DBC].

== Running CI tasks locally
192+
193+
Since this pipeline is purely Docker-based, it's easy to:
194+
195+
* Debug what went wrong on your local machine.
196+
* Test out a a tweak to your `test.sh` script before sending it out.
197+
* Experiment against a new image before submitting your pull request.
198+
199+
All of these use cases are great reasons to essentially run what the CI server does on your local machine.
200+
201+
IMPORTANT: To do this you must have Docker installed on your machine.
202+
203+
1. `docker run -it --mount type=bind,source="$(pwd)",target=/spring-data-r2dbc-github -v /usr/bin/docker:/usr/bin/docker -v /var/run/docker.sock:/var/run/docker.sock adoptopenjdk/openjdk8:latest /bin/bash`
204+
+
205+
This will launch the Docker image and mount your source code at `spring-data-r2dbc-github`.
206+
+
207+
2. `cd spring-data-r2dbc-github`
208+
+
209+
Next, test everything from inside the container:
210+
+
211+
3. `./mvnw -Pci,all-dbs clean dependency:list test -Dsort -B` (or whatever test configuration you must use)
212+
213+
Since the container is binding to your source, you can make edits from your IDE and continue to run build jobs.
214+
215+
NOTE: Docker containers can eat up disk space fast! From time to time, run `docker system prune` to clean out old images.
