[Alpha] Merge diff of Resource configuration files into a destination (3-way)
[Alpha] Merge diff of Resource configuration files into a destination (3-way)
Merge3 performs a 3-way merge by applying the diff between 2 sets of Resources to a 3rd set.
Merge3 may be for rebasing changes to a forked set of configuration -- e.g. compute the difference between the original set of Resources that was forked and an updated set of those Resources, then apply that difference to the fork.
If a field value differs between the ORIGINAL_DIR and UPDATED_DIR, the value from the UPDATED_DIR is taken and applied to the Resource in the DEST_DIR.
For information on merge rules, run:
kustomize cfg docs-merge3
kustomize cfg merge3 --ancestor a/ --from b/ --to c/
