Database migrations in Kubernetes applications with Flyway

I’ve recorded a video how to migrate databases for applications that are deployed in a managed Kubernetes environment using Flyway and init containers. In order to achieve zero-downtime deployments, we need to make sure that our persistence concept supports N-1 compatibility, which requires us to be able to migrate our database schemas, ideally from reproducible scripts stored in version control. ...

Migrating Neo4j graph schemas in Kubernetes

When running enterprise applications with zero-downtime, we need to be able to perform database schema migrations without disrupting active users. This is important not just for relational databases, but also for graph databases such as Neo4J, which don’t enforce a schema on write. However, it still makes sense to refactor your graph and to keep your graph data model in ...

Deploying a Neo4J single core on managed Kubernetes

Besides running a database cluster, it might already be sufficient for your project to deploy a single instance. In the following video I’ll explain how to deploy a single core Neo4J instance using Helm to a managed Kubernetes cluster. I’ll be using a forked and modified version of the official Helm chart, which you can find in this GitHub repository ...

Deploying a Neo4J cluster on managed Kubernetes

I’ve created some videos on how to deploy both a Neo4J cluster and standalone instance to a manged Kubernetes cluster. When running a database or any service with persistence concern, we need to take more considerations into account, most importantly how to implement persistent storage as well as automated processes such as backups. In the following video I’ll explain how ...

Java/Cloud: How to Quickly Create a Kubernetes-ready REST Microservice

It is safe to say that the Microservice + Cloud combination is all the rage these days. Microservices are being developed more than ever, in turn resulting in an increase in the number of application deployments. During the past decade, containerization and orchestration tools such as Docker and Kubernetes were developed, making the microservice pattern really easy to adopt. This ...
