docker build image error - invalid reference format

[v-dev]

For the "Create and Run an Image in a Pipeline" section, I got the following error when copying/pasting your alpine-curl.yml into my bitbucket repo:

I removed the ${{CF_REPO_OWNER}} reference from the yml and then the build was successful.
