# Rationale for copying charts to a gitignored folder before modifying helm versions and docker image tags:
#
# * we want to keep git history clean and not clutter it with version bump commits
#   * synchronizing version bumps with multiple PRs, releases to master and merges back to develop is hard to do in git
#   * we don't want to spend time modifying version tags manually all the time
# * we want version pinning for helm charts and docker images for reproducible results during deployments
#   * CI will keep track of versioning and upload charts to an S3 mirror
#   * if you need to do this locally, also use this make target and set desired versions accordingly.
