Kubernetes is an open-source system for automating deployment, scaling and management of containerized applications that was originally designed by Google and donated to the Cloud Native Computing Foundation. It aims to provide a "platform for automating deployment, scaling, and operations of application containers across clusters of hosts".It supports a range of container tools, including Docker.

Creating a single microservice is a well-understood challenge. Creating a cluster of load-balanced microservices that are resilient and self-healing is not so easy. Managing that cluster with rollouts and rollbacks, scaling individual services on demand, and securely sharing secrets and configuration among services is even harder. Kubernetes, an open-source container management system, can help with this. In this video, Robert Kubis and Steffen Hanikelwith work with a simple microservice, containerize it using Docker, and scale it to a cluster of resilient microservices managed by Kubernetes. Along the way, you'll learn what makes Kubernetes a great system for automating deployment, operations, and scaling of containerized applications. In this session, FlixBus joins us to talk about experiences and best practices adopting and running Kubernetes in production.

It shows all the gateways, channels and bridges of the application, regardless of whether they are configured using Java or XML annotations.

The IDE also received code completion and navigation for such integration annotations as @BridgeTo/From and @EnablePublisher:

In the new version of IntelliJ IDEA, you can view the dependencies during the execution of the Spring Boot application as a diagram through the control panel. To do this, go to the "Endpoints" section and enable the "Diagram Mode" function:

If there are too many beans in the project, the non-user codes can be disabled using the new "Show / Hide Library Beans" switch:

In addition, in 2018.2, you can start, modify, and test the display of HTTP requests in the "Endpoints" tab:

A complete list of improvements and changes is available in the technical update document. According to the developers, a lot of work has been done to improve performance in large projects.
