Debugging in Kubernetes

While Kubernetes offers a self-healing deployment platform, there is a fair chance a developer will run into issues that require deeper analysis and debugging to identify configuration problems. Kubernetes supports a loosely coupled, distributed architecture by allowing an application to be broken down into smaller, granular modules—each of which can be written and managed independently.


Experimenting with remote debugging: Node.js runtime code injection

Remote debugging is fun to play around with. This article describes a method to dynamically change the behavior of a running Node.js process by enabling the remote inspector interface and then use the Chrome debug protocol. On Linux and MacOS, it is possible to send a SIGUSR1 signal to a running Node.js process. The process will open a websocket server listening on local interfaces only.
