What defines Ansible Galaxy role's version?

Question

In documentation of Ansible Galaxy I found you can install specific version of a role. I was not able to find what defines the version in role itself. Is it Git tag, some key in meta/main.yaml, or something else?

Answer 1

To install a version simply git tag it:

$ git tag v1.0
$ git push origin v1.0

Then from the man page you can install the specific Role version:

"ansible-galaxy install [options] [-r FILE | role_name(s)[,version] | tar_file(s)]"
