Kubernetes for Java developers

Microservices have become the de facto standard these days, so Java developers are now expected not only to write code but also to deliver it to various environments. There’s no need to reinvent the wheel, since ready-made solutions already exist: Docker for containerizing microservices, and Kubernetes as a container orchestration platform. With these tools, a Java developer can efficiently deploy, scale, test, monitor, and debug their microservice, both on a local machine and in remote environments.

Goals and objectives

  • Understand the principles of building cloud-native microservices, using the Spring Boot platform as an example
  • Significantly shorten the time it takes to learn Docker/Kubernetes well enough to use them in practice
  • Learn about best practices and anti-patterns drawn from the experience of many teams and companies
  • Dig deep enough into how things work to apply the tools with a clear understanding of what they do
  • Get pointers for further in-depth study
  • Understand how the Docker/Kubernetes ecosystem is evolving and where to find solutions to the problems and challenges you face
