title: Docker with BitBucket
body: <p>I'm trying to make automatic publishing using docker + bitbucket pipelines; unfortunately, I have a problem. I read the pipelines deploy instructions on Docker Hub, and I created the following template:</p>
  
  <pre><code># This is a sample build configuration for Docker.
  # Check our guides at https://confluence.atlassian.com/x/O1toN for more examples.
  # Only use spaces to indent your .yml configuration.
  # -----
  # You can specify a custom docker image from Docker Hub as your build environment.
  image: atlassian/default-image:2
  
  pipelines:
    default:
      - step:
          services:
            - docker
          script: # Modify the commands below to build your repository.
            # Set $DOCKER_HUB_USERNAME and $DOCKER_HUB_PASSWORD as environment variables in repository settings
            - export IMAGE_NAME=paweltest/tester:$BITBUCKET_COMMIT
  
            # build the Docker image (this will use the Dockerfile in the root of the repo)
            - docker build -t paweltest/tester .
            # authenticate with the Docker Hub registry
            - docker login --username $DOCKER_HUB_USERNAME --password $DOCKER_HUB_PASSWORD
            # push the new Docker image to the Docker registry
            - docker push paweltest/tester:tagname
  </code></pre>
  
  <p>I have completed the data, but after doing the push, I get the following error when the build starts:</p>
  
  <blockquote>
    <p>unable to prepare context: lstat/opt/atlassian/pipelines/agent/build/Dockerfile: no dry file or directory</p>
  </blockquote>
  
  <p>What would I want to achieve? After posting changes to the repository, I'd like for an image to be automatically built and sent to the Docker hub, preferably to the target server where the application is.</p>
  
  <p>I've looked for a solution and tried different combinations. For now, I have about 200 commits with Failed status and no further ideas.</p>
