kubedump is a tool for dumping manifests from your Kubernetes clusters. It’s highly inspired by the available shell scripts (1, 2) and just a Go implementation with similar behaviour I wrote mostly for fun.
A clear drawback of the Go implementation is the enormous binary size for such small functionality. Currently, the code is not even 200 lines of code but due to the imports from the Kubernetes ecosystem, the binary is around 30 MB. Nevertheless, having a binary instead of a shell script might have other benefits, e.g. no other required dependencies and compared to the scripts it seems to be very fast.
Make sure to check the repository for the latest version.
