Debugging apps running in Kubernetes An overview of the tooling available

Debugging apps running in Kubernetes can be challenging due to the lack of tooling. Learn about Ksync, Squash, and Telepresence, tools that can help you sync local files, debug pods, and tunnel into your cluster.

Key takeaways
  • Debugging tools are missing in Kubernetes, especially for developer workflows.
  • Ksync is a tool to sync local files to a directory in a Kubernetes pod.
  • Squash is a debugger that allows developers to debug pods locally.
  • Telepresence creates a tunnel between a local developer machine and a Kubernetes cluster.
  • Docker images are updated in a pod, not in a local environment.
  • Ksync can sync files, including config files, during development.
  • Squash needs a container with the debugger to be effective.
  • Telepresence requires a VPN and is not compatible with multiple VPNs.
  • Helm is a package manager for Kubernetes that provides pre-built charts.
  • Ksync, Squash, and Telepresence are all still in their infancy and need improvement.
  • Developers need to understand how to deploy and debug applications in Kubernetes.
  • The debugging process can be complex and requires patience and understanding of Kubernetes concepts.
  • Kubernetes provides a sophisticated way to manage and orchestrate applications, but debugging can be challenging.
  • Developers need to understand how to use Ksync, Squash, and Telepresence to effectively debug and develop applications in Kubernetes.
  • Debugging in a Kubernetes cluster can be difficult and requires a combination of tools and understanding of Kubernetes concepts.
  • The lack of debugging tools in Kubernetes can slow down the development process and make it more difficult to identify and fix issues.
