Spring Boot + Cockroach DB in Kubernetes/OpenShift


In my previous post, I showed why CockroachDB might help you if you need a cloud native SQL database for your application. I explained how to install it in Kubernetes/OpenShift and how to validate that the data is replicated correctly.

In this post, I am going to show you how to use Cockroach DB in a Spring Boot application. Notice that Cockroach DB is compatible with PostgresSQL driver, so in terms of configuration is almost the same.

In this post, I assume that you have already a Cockroach DB cluster running in Kubernetes cluster as explained in my previous post.

For this example, I am using Fabric8 Maven Plugin to smoothly deploy a Spring Boot application to Kubernetes without having to worry so much about creating resources, creating Dockerfile and so on. Everything is automatically created and managed.

For this reason, pom.xml looks like:


Notice that apart from defining Fabric8 Maven Plugin I am also defining to use Spring Data JPA to make the integration between Spring Boot and JPA easier from the point of view of the developer.

Then you need to create a JPA entity and Spring Data Crud repository to interact with JPA.

Also, we need to create a controller who is responsible to get incoming requests, use the repository to make queries to DB and return results back to the caller.

Finally, you need to configure JPA to use the desired driver and dialect. In case of Spring Boot this is done in application.properties file.


The most important part here is that we need to use the PostgeSQL94 dialect. Notice that in url, we are using the postgresql jdbc url form. That's fine, since Cockroach uses the Postgres driver.

Now we need to create the database (customers) and the user (myuser) as configured in application.properties. To make it so, you just need to run cockroach shell and run some SQL commands:


Finally, you can deploy the application by running mvn clean fabric8:deploy. After that, the first time might take longer since needs to pull Docker images, you can start sending queries to the service.

As you can see it is really easy to start using a cloud-native DB like Cockroach DB in Spring Boot. If you want you can do exactly the same as in my previous post and start running queries to each of the nodes to validate that data is available correctly.
