Go KoolKit

KoolKits (Kubernetes toolkits) are language-specific container images, that contain a (highly-opinionated) set of tools for debugging applications running in Kubernetes pods. You can read more about KoolKits here or learn about the motivation behind this project here.

To get started, first add the shorthand kk command to your shell by pasting the following snippet into your shell:

echo "## KoolKits - Shorthand
kk() {
	kubectl debug -it $1 --image=lightruncom/koolkits:$2 --image-pull-policy=Never --target=$3
}" >> ~/.bashrc
source ~/.bashrc

Then run the Go KoolKit with your pod:

kk <POD-NAME> golang <DEPLOYMENT-NAME>

The Go KoolKit contains the following Go utilities (available on $PATH wherever applicable):

• delve - Delve is a debugger for the Go programming language.
• pprof - pprof is a tool for visualization and analysis of profiling data.
• fzf - fzf is a general-purpose command-line fuzzy finder.
• alp - Talp is Access Log Profiler.
• go-callvis - go-callvis is a development tool to help visualize call graph of a Go program using interactive view.
• gvm - GVM provides an interface to manage Go versions.
