Kubernetes allows you to automate the deployment, scaling, and operations of application containers across clusters of hosts. It’s a management tool used to maintain and track a lot of Docker Containers. Kubernetes also handles all kinds of clouds, virtual machines, and physical machines in a uniform way to make it easy to deploy your application to any of them or even a combination deployment on clouds, virtual machines, and/or physical machines. It is also possible to use Kubernetes while running your application using Payara Micro.
Check out the following resources to learn more about using the Payara Platform with Kubernetes.
The Payara Platform is designed as a cloud-native open source server runtime, with container-friendly features built-in. In this datasheet you’ll learn why you should use containers and the container-friendly features of Payara Platform and how to improve portability of your applications.

This guide will take you through more advanced Kubernetes concepts and show you how to scale and cluster an application with Payara Micro on Kubernetes.
Learn how to create a new Kubernetes cluster in Amazon Web Services and to set up a deployment using a sample WAR application running on Payara Micro.
This guide shows you how to create a new Kubernetes cluster in Microsoft Azure and to set up a deployment using a sample WAR application running on Payara Micro.
Within this book, you will be guided through setting up and your first explorations of the Kubernetes API within a plain Java program. We explore the concepts of resource listeners, programmatic creation of deployments and services and how this can be used for your custom requirements.
Learn how to run an application with Payara Micro on a Kubernetes Cluster. We’ll use a simple war application packaged in a Docker container and prepare it to run on a Kubernetes cluster.

Containers and the Payara PlatformHow to Migrate to the Payara Platform
When using Kubernetes, for more complex scenarios it is not enough to start the deployment or service. You also need to execute some commands within the containers to perform some configuration or initialization of the environment. To automate configuration or the process of initializing an environment, you can write a Kubernetes operator.The Payara Kubernetes Operator, released as a Proof of Concept or Minimum Viable Product (MVP) in our June Payara Platform release, helps you to set up a Payara cluster using the Deployment Group feature of the Payara Server.
These days, it seems Kubernetes is a topic that is never too far from people's lips. The tool, and the associated tools built around it, are talked about so often it seems it's the only subject important to developers these days - especially as the IT world becomes increasingly orientated towards cloud and microservices. But in spite of all the conversation around Kubernetes... do you really need Kubernetes for your environment? Or is it just another case of the next 'new and shiny' object, with people distracted by the novelty and possibility, rather than the facts? In this blog, I'll take a closer look at why Kubernetes might be a case of the hype outweighing the helpfulness in most cases.
Foojay's Virtual JUG tour is in full swing, with the Java community platform organising a succession of online events at JUGs all across the world. As contributors to the Foojay platform, supporters from the start and members of itsinaugural advisory board, Payara Services was happy to participate. Rudy de Busscher presented his talk, 'Creating a Kubernetes Operator in Java', for the St. Louis Java User Group as part of the tour. You can now watch this, and also hear Geertjan Wielenga introduce the concept of Foojay to start the talk.
In this day and age, securing enterprise platforms is a challenge that developers and consultants tackle in an uninformed manner, producing subpar solutions in most cases. To combat this pattern, third-party security services such as Auth0 have been devised to externalize the security of services, and they focus on stable implementations of common enterprise use cases (identity management, OAuth compatibility, and so on), and platforms such as Eclipse MicroProfile allow for their easy integration with enterprise Java microservices. Moreover, in combination with Kubernetes, MicroProfile is a very powerful tool to simplify securing microservices, monitoring them and creating reproducible deployments.
Introduction With Container orchestration tools like Kubernetes and Docker Swarm, you can add instances quite easily. Depending on the type of clustering you need or use for your application, some scenarios are easier to implement than others.
Introduction Application updates are required as part of the normal maintenance process of your application lifecycle management. These updates should be as smooth as possible, and especially for a micro-services environment, performed with zero-downtime of your Payara Micro application. The Kubernetes Rolling Upgrades feature can help you with this.
