I need to build docker image form the source code of the current repository, run a container, then execute some API calls. How to do that with the github action?

name: Docs Generator
on:
  pull_request:
    types: [opened]

jobs:
  pr-labeler:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
          uses: actions/checkout@v2
          with:
            ref: ${{ github.event.pull_request.head.ref }}
            repository: ${{ github.event.pull_request.head.repo.full_name }}
          
      - name: Get the version
        id: vars
        run: echo ::set-output name=tag::$(echo ${GITHUB_REF:10})
        
      - name: Build the tagged Docker image
        run: docker build . --file Dockerfile --tag service:${{steps.vars.outputs.tag}}
        
      - name: Run docker image
        docker run -v ${{ inputs.path }}:/src service:${{steps.vars.outputs.tag}}

      - name: Call API
        run: |
          curl +x http://localhost:8080/test

For this purpose, you could use a combination of https://github.com/marketplace/actions/build-and-push-docker-images and https://github.com/addnab/docker-run-action

The first would build and publish a container, and the second would take this container and run your commands there.

The example is below. I don't use this setup myself but I have tested it. Replace username/container with your username and container.

name: Docker Image CI

on:
  push:
    branches: [ master ]
  pull_request:
    branches: [ master ]

jobs:
    compile:
        name: Build and run the container
        runs-on: ubuntu-latest
        steps:
          - name: Set up QEMU
            uses: docker/setup-qemu-action@v1
          - name: Set up Docker Buildx
            uses: docker/setup-buildx-action@v1
          - name: Login to DockerHub
            uses: docker/login-action@v1
            with:
              username: ${{ secrets.DOCKERHUB_USERNAME }}
              password: ${{ secrets.DOCKERHUB_TOKEN }}
          - name: Build and push
            uses: docker/build-push-action@v2
            with:
              push: true
              tags: username/container
          - name: Check out the repo
            uses: actions/checkout@v2
          - name: Run the build process with Docker
            uses: addnab/docker-run-action@v3
            with:
                image: username/container:latest
                options: -v ${{ github.workspace }}:/data
                run: |
                    echo "Hello World"

Note that building a container is quite a long task and might deplete your Github Action limits quickly. You might consider building/publishing a container separately, or add better caching here (i.e. to rebuild it only on Dockerfile change)

Note that you need to set up DOCKERHUB_USERNAME and DOCKERHUB_TOKEN secrets.

Instead of echo "Hello World", use the commands you want to run. The repo data will be in the /data directory, for this setup.
