In the Java world it is rather common to use something called application servers. These are meta-applications that provide your applications an environment with things like database abstractions and the like, as well as admin interfaces.

It solves some of the same problems you might reach for Kubernetes or OpenShift for, your application gets access to external resources in structured ways and you get to look at dashboards.

GlassFish is an example of such an application server. WildFly is more common, and is the artist formerly known as JBoss. If you have some knowledge in the enterprise Java ecosystem you can quickly and easily (or maybe not, it depends) deploy your creations into these.
