Kubernetes pod as a Bastion Host

In Cloud Native apps private networks, databases and services are a reality. An infrastructure can be fully private and only a limited number of entry points can be available. Obviously the more restricted the better. Still there are cases where there has not been any infrastructure setup for the private services and ways to link towards them. however if there ...

Replacing Docker Desktop with hyperkit + minikube

MacOS is a Unix but it isn’t a Linux so, unfortunately, if/when we need to use linux-y things like docker we need to install a VM just like in the Windows world. That’s of course also true for docker. Like most people I’ve been using Docker Desktop for a lot of years to get my fix for container. It works ...

Data Gateways in the Cloud Native Era

These days, there is a lot of excitement around 12-factor apps, microservices, and service mesh, but not so much around cloud-native data. The number of conference talks, blog posts, best practices, and purpose-built tools around cloud-native data access is relatively low. One of the main reasons for this is because most data access technologies are architectured and created in a ...

Container Orchestration | Definition, Benefits & How It Works

Container Orchestration | Definition, Benefits & How It Works In the 1970’s, the concept of a container-based application emerged to transform the IT world. For the first time, the software was deployed consistently and reliably regardless of the target environment’s changes (private or public cloud, personal computer, etc.). With the development of containers, container orchestration has become a trending topic ...

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 ...

How to restore a Neo4J backup on managed Kubernetes

In the following video I’ll explain how to restore backups of Neo4J instances to a fresh instance that runs in a managed Kubernetes environment. The backup contents will be taken from a persistent volume to which we previously wrote the backup. In this previous post you can see how to take backups in the first place. Try it yourself Again, ...

How to backup Neo4J on managed Kubernetes

In the following video I’ll explain how to take full and incremental backups of Neo4J instances that run in a managed Kubernetes environment. We’ll use additional pods to take remote backups and store the backup data on persistent volumes which are provided by our managed environment. In case you’re wondering how to deploy Neo4J to managed Kubernetes, have a look ...

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 ...
