J-Spring 2021: Daniel Bryant – Debugging Java Microservices Running on Kubernetes with Telepresence

Many Java-based organizations adopt cloud native development practices with the goal of shipping features faster. The technologies and architectures may change when we move to the cloud, but the fact remains that we all still add the occasional bug to our code. The challenge here is that many of your existing local debugging tools and practices can’t be used when everything is running in a container or deployed onto Kubernetes running in the cloud. This is where the open source Telepresence tool can help.

Join me to learn about:

– The challenges with scaling Kubernetes-based Java development i.e. you can only run so many microservices locally before minikube melts your laptop
– Quick overview of options and tooling e.g. “kubectl port-forward”, Skaffold, ksync, Telepresence etc
– An exploration of how Telepresence can “intercept” or reroute traffic from a specified service in a remote K8s cluster to your local dev machine
– The benefits of getting a “hot reload” fast feedback loop between applications being developed locally and apps running in the remote environment
