title: Is there a way to set path for docker build with the github action plugin docker/build-push-action@v1
body: <p>I have a docker build action as below</p>
  <pre><code>      - name: build-push
          uses: docker/build-push-action@v1
          with:
            username: ${{ DOCKER_USERNAME }}
            password: ${{ DOCKER_PASSWORD }}
            repository: &lt;repo&gt;
            tags: tag
            push: true
            dockerfile: ./&lt;path-to-dockerfile&gt;/Dockerfile
  </code></pre>
  <p>The dockerfile has instructions to ADD few files to the docker image as below</p>
  <pre><code>ADD file1 .
  ADD file2 .
  ADD file3 .
  </code></pre>
  <p>the structure of github is:</p>
  <pre><code>-.github
  -folder1------------
                     |
                     folder2-------------
                                         |
                 -----------------------docker--------
                 |             |           |          |
              file1          file2        file3      Dockerfile
  </code></pre>
  <p>The issue is that the GitHub action is unable to find <strong>file1</strong>, <strong>file2</strong> and <strong>file3</strong> as it is looking in the level of <strong>folder1</strong>. The error generated is</p>
  <pre><code>ADD failed: file not found in build context or excluded by .dockerignore: file1: file does not exist
  </code></pre>
  <p>I do not want to modify the path in dockerfile as <code> ADD ./folder1/folder2/file1 .</code>.
  So how do I add path or change directory from the GitHub Action part using docker/build-push-action@v1 ?</p>
