Presentation: Tweet"Java-Based Microservices, Containers, Kubernetes - How To"

Join this session to learn how to create a Java-based microservice using Spring Boot, containerize it using Maven plugins, and subsequently deploy a fleet of microservices and dependent components such as Redis using Kubernetes.

Spring Boot makes creating microservices fast and easy – when it comes to running a single instance. Like most Java applications, the harder part is usually the clustering and fail-over configurations.

First, we'll go over how to get started with Spring Boot, and, subsequently, using Maven plugins to generate and create Docker images during the build process.

Next, we'll go over some basic architecture and configurations, such as:

• Configuring Spring Session
• Using Redis as the session store
• Testing the configuration locally with container linking
• Tips and tricks for faster startup (/dev/./urandom is your friend)
• Finally, with the images, we'll deploy the microservice into Kubernetes:

Defining pods and services

• Linking microservices to Redis using Kubernetes
• Perform rolling upgrades of the application
• Canary new versions of the microservices into the fleet

The best part is – we can visualize all these activities happening in Kubernetes.
