| # This workflow could almost use the default GITHUB_TOKEN, if we were to | |
| # push the branch into this repo. However, GitHub Actions has recursion | |
| # avoidance that would prevent CI from running on the PR: | |
| # | |
| # https://github.com/peter-evans/create-pull-request/blob/28fa4848947e/docs/concepts-guidelines.md#workarounds-to-trigger-further-workflow-runs | |
| # | |
| # So we create the PR using a separate Personal Access Token in | |
| # COREOSBOT_RELENG_TOKEN, belonging to a machine account. That allows CI to | |
| # run when the PR is first created. However, it's also possible to rerun | |
| # the workflow and have it force-push the branch, reusing the same PR. In | |
| # that case the push also cannot come from GITHUB_TOKEN, or CI will not | |
| # rerun. Thus we also do the push using COREOSBOT_RELENG_TOKEN. Since we | |
| # don't want to give the machine account privileges to this repo, we push | |
| # to a forked repo owned by the machine account. | |
