Possible to use more than one buildpack for static site in App Platform?

@soulchild 👋

This is possible to do today, but you’ll need to build using a Dockerfile, since we don’t yet support configuring multiple or overriding buildpacks on the App Platform.

I forked your repo and added a Dockerfile.build that looks like this:

FROM starefossen/ruby-node

ENV BUNDLER_VERSION=2.1.4
RUN gem install bundler -v ${BUNDLER_VERSION}

COPY . /app
WORKDIR /app
RUN bundle install && npm install && npm run build

We’re currently missing support in the UI for including an output_dir field that’s required for Dockerfile-based static builds, so you’ll need to submit using doctl and a spec YAML directly in the meantime. I added a .do/app.yaml file to the repo; you’ll want to use a similar one that looks like this:

name: mountain-goat
static_sites:
- name: site
  github:
    repo: cupnoodle/mountain_goat
    branch: master
    deploy_on_push: true
  dockerfile_path: Dockerfile.build
  output_dir: /app/_site

You can then create the app using doctl with:

doctl apps create --spec .do/app.yaml
