github actions beta

first impressions on github actions beta

A full 10 months after clicking "Join Beta", I'm finally in.

Docs are scarce and already outdated, it's now yaml instead of hcl.

• workflow.yaml syntax: docs
• action.yml syntax: docs

Build stuff

Right now, I like docker containers, so build on push:

 1on: push
 2jobs:
 3  job1:
 4    runs-on: ubuntu-latest
 5    steps:
 6      - uses: actions/checkout@master
 7      - run: docker build -t some_image .
 8      - run: docker login registry -u username -p $TOKEN
 9        env:
10          TOKEN: ${{ secrets.SOME_SECRET }}
11      - run: docker push some_image

model

you get a vm with a bunch of outdated stuff installed

run commands with jobs.jobid.steps[x].run:

run actions with jobs.jobid.steps[x].uses:

actions

js or a container with extra metadata for input/output validation, refer to by:

• user / repo (/ path) @ ref
• . (current repo root) / path / to / action / dir
• docker://some-image:tag

notes

secrets are filtered from log output, yay? but now how do we debug?

apparently there's no way to set global substitutions?

also doesn't integrate well with the package registry beta

there are 3 ways to run a container as a step:

1. run: docker run some-image
2. uses: docker://some-image
3. uses: user/repo (assuming a Dockerfile and action.yml exists)
