Summary
make render-diffwill run a script, that connects to the current cluster inKUBECONFIGand runs a diff against the current AppCat branch.It leverages Crossplane's crank utility to render the result of a single function reconcile. It then uses
dyff, a YAML and K8s aware diff tool, to actually show the diff itself.Limitations: it can currently only generate a single reconcile run against the current state. If a function needs multiple reconciles to change the desired state, it won't show up in the diff.
Also, it will only work against a cluster that has at least this version of the AppCat function installed. Otherwise crank won't be able to render it correctly.
