This is kind of meta: I made a separate repo todayilearned
with the website for the content in this repo, and I wanted to trigger a new deploy whenever I pushed a new TIL.
The TL;DR is that there needs to be a GitHub Actions workflow in each repo: one in the "source" to send a repository_dispatch
event to the "destination", and one in the destination to do the actual building/deploying/what have you.
I'm sure this has been written in a zillion different places, but it took me a bit of searching to figure out so here goes:
-
Modify the destination repo's workflow YAML file to run the workflow on
repository_dispatch
events:on: push: branches: [main] repository_dispatch: # this line tells the workflow to run on `repository_dispatch` events types: [deploy] # this tells what event types should trigger a workflow run; if it's omitted, it'll just run on every event
-
Create a Personal Access Token.
- The new fine-grained tokens require an expiration date with a max of two years, at which point I'll definitely have forgotten about all this. But luckily I'll be able to refer back to this TIL to figure it out again!
- The only repository access needed is the destination (i.e. the one receiving the event).
- The only required permissions are read and write access for
content
(which covers the dispatch event) andmetadata
(which I think is mandatory for all personal access tokens).
-
At this point, you can test things out manually with a cURL (replace
PERSONAL_ACCESS_TOKEN
,USER
andREPO
with the appropriate values):curl --request POST \ -H "Accept: application/vnd.github.everest-preview+json" \ -H "Authorization: token PERSONAL_ACCESS_TOKEN" \ --data '{ "event_type": "deploy" }' https://api.github.com/repos/USER/REPO/dispatches
If things are set up correctly, this should trigger a workflow run.
-
Add the personal access token in the Actions secrets settings of the source repo.
-
Add a workflow YAML file to the source repo that runs the cURL command above:
name: Deploy on: push: branches: - main jobs: deploy: runs-on: ubuntu-latest steps: - name: Dispatch to workflows run: | curl -H "Accept: application/vnd.github.everest-preview+json" \ -H "Authorization: token ${{ secrets.PERSONAL_ACCESS_TOKEN }}" \ --request POST \ --data '{ "event_type": "deploy" }' https://api.github.com/repos/USER/REPO/dispatches
