kube-compare

Take snapshots of your K8s cluster yaml and compare them later on

Using

To dump & compare all resources in the cluster:

./kubecompare dump -f 17-feb-2023-dump-all
./kubecompare compare -f 17-feb-2023-dump-all

To dump & compare specific types of resources:

./kubecompare dump -f 17-feb-2023-dump-pods-ss-ds -r "pods statefulset daemonset"
./kubecompare compare -f 17-feb-2023-dump-pods-ss-ds

For nicer output, dyff can be used.

Once dyff is installed run the following command to use it instead of the default kubectl diff:

export KUBECTL_EXTERNAL_DIFF="dyff between --omit-header --set-exit-code"

Updating
