split-k8s-yaml
We've all been there. We have two enormous YAML
files, each with many documents in them. They have
come from maybe helm template or kustomize.
We want to see the difference.
If one was running, we could use kubectl diff. But,
not here.
So, we can run this tool.
Usage:
split-yaml old.yaml new.yaml
diff old new
(I use kdiff3, you might enjoy meld if you want a graphical view).
What it does is, for each yaml file on the input, create a directory by the basename of the file, and then split all the objects in it, keeping the names unique (apiVersion/kind/namespace/name).
