Trigger Github Action only on new tags?

Question

Is there a possibility to tigger a github action only if a new version (which comes with a new tag) is pushed? I don't want run them on every push into master, but I also want to avoid creating a release branch.

Answer 1

Use the following syntax:

on:   push:     # Pattern matched against refs/tags     tags:               - '*'           # Push events to every tag not containing / 

For hierarchical tags:

on:   push:     # Pattern matched against refs/tags     tags:               - '**'           # Push events to every tag including hierarchical tags like v1.0/beta

Answer 2

I got it to work with

on:   push:     tags:       - '*' 

I found out that if the tag was previously created (locally) before the workflow was created, no matter how many times I deleted and re-pushed the tag, it would not trigger until I deleted the tag locally and recreated it. The action does not seem to work for tags created before the workflow.
