Docker Builder for Homebots services

Builds and pushes a new Docker image with an app or microservice inside.

Use a prebuilt base image that runs anything from /home/app folder. This action will just grab some files, add to the base image under home/app and push the new image to a repository.

Inputs

image-name

String. Name of the image to build

registry

String. The registry to push the image to. Also used to find the base image, based on service type

targets

Multiline string. Paths to files/folders to be added to the image.

File structure

A service has a json file in its root directory, called service.json

The only required field is type, which is the name of the service type.

Other options depend upon the service type.

Example

name: 'Build a node app'
on: [push]

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - name: 'Checkout'
        uses: actions/checkout@v2

      - name: 'Build image'
        uses: homebots/docker-builder@v1
        with:
          image-name: app
          targets: |
            ./index.js
          extra-commands: |
            RUN npm install
            ENTRYPOINT [ "node", "index.js" ]

      - name: 'Check resulting image'
        run: docker run --rm -it app

How it works

The registry + the service type are used to find the base image.

Then a Dockerfile is generated, using the base image, and the service is built.

That service is then tagged and pushed to the registry.
