For an example, see

• A CI/CD pipeline where this snippet is used (twice, by !reference to inline definition): https://gitlab.com/milohax/milohax/-/blob/main/.gitlab-ci.yml
• A Dockerfile to modify a Ruby-Alpine image, adding git and rsync utilities: $2220897

Note:- must --exclude=.* in the rsync, to avoid clobbering git credentials in the new clone

Also, you can skip triggering a pipeline from the pipeline with [skip ci] (or [ci skip] if Yoda-speak you like) in the commit message
