The primary issue is exposing the debug ports for your locally running IDE or debugger to connect to. ![]() Remote debugging against Java apps running in Kubernetes can be challenging. ![]() Difficulties with Debugging Java Apps Running in Kubernetes This enables you to spin up a single service or small collection of services locally and debug your apps using your existing tools while still being able to access the remote services as if you were working in the cluster. This article walks you through the use of Telepresence for seamlessly connecting your local development machine running all of your familiar debug tooling to a remote Kubernetes cluster that contains the rest of your microservices. The open source Telepresence tool can help. This then opens up the challenges of remote debugging, and the associated fiddling with debug protocols and exposing ports correctly. However, when you are working with a system that is composed of a large number of microservices running in a Kubernetes cluster, the approach you take to debugging has to change.įor one, when you want to conduct integration tests with a service you typically can’t run all of your dependent services on your local machine. A change in approach is required! Debugging Cloud Native Apps Requires a New ApproachĮasy and efficient debugging is essential to being a productive engineer. 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 on the cloud. 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. Many Java-based organizations adopt cloud native development practices with the goal of shipping features faster. Tutorial: Learn to locally debug Java microservices with IntelliJ IDEA and Telepresence connected to a remote Kubernetes cluster This is a guest blog post by Daniel Bryant, from Telepresence ![]()
