title: Including docker socket in Dockerfile
body: <p>Can we add docker.sock from host to container using Dockerfile? What I want to do is issue docker commands (pull, tag and push) inside container. I know the "-v /var/run/docker.sock:/var/run/docker.sock" in docker run command but I need to include the same inside Dockerfile to build it. Here below is my Dockerfile :-</p>
  
  <pre><code>FROM centos:latest
  RUN yum update -y &amp;&amp; yum install epel-release -y
  RUN yum install python-pip -y
  RUN pip install requests
  COPY docker_push.py /tmp
  COPY config.ini /tmp
  RUN yum install docker-io -y
  ENTRYPOINT ["python", "/tmp/docker_push.py"]
  </code></pre>
