how to trigger a gh-action only if the issue is created by the repo owner
what i learned
you can add an if key to a job to conditionally run jobs. you also have a lot of metadata available in github actions regarding the event that triggered it and the repo it is on.
put together you can add a condition like:
.github/workflows/issue-to-md.yml
...
job:
job_name:
runs_on: ubuntu
if: ${{ github.event.issue.user.login == github.repository_owner }}
...
how i learned
i have my issue-to-md.yml workflow to create til posts from issues on my repo but i realized that technically anyone could open an issue which would trigger the action and create a pull request. adding this condition ensures it'll only run if i am the one writing the issue. using the available metadata makes it reusable (i don't have to hardcode my own username).
