There are many interesting tools and solutions around Kubernetes, which may help you in running and managing applications. However, you should also not forget about some interesting tools and solutions offered by a framework you use. Let me give you some examples. One of them is the Spring Boot Admin. It is a useful tool designed for monitoring Spring Boot applications across a single discovery. Assuming you are running microservices on Kubernetes you may also install Spring Boot Admin there.

There is another interesting project within Spring Cloud – Spring Cloud Kubernetes. It provides some useful features that simplify integration between a Spring Boot application and Kubernetes. One of them is a discovery across all namespaces. If you use that feature together with Spring Boot Admin, you may easily create a powerful tool, which is able to monitor all Spring Boot microservices running on your Kubernetes cluster. For more details about implementation details you may refer to my article Spring Boot Admin on Kubernetes.

Sometimes you may use Spring Boot integrations with third-party tools to easily deploy such a solution on Kubernetes without building separated Deployment. You can even build a cluster of multiple instances. This approach may be used for products that can be embedded in a Spring Boot application. It can be, for example RabbitMQ or Hazelcast (popular in-memory data grid). If you are interested in more details about running Hazelcast cluster on Kubernetes using this approach please refer to my article Hazelcast with Spring Boot on Kubernetes.
