title: How to disable and enable internet connection from within Docker container?
body: <p>I am clearing /etc/resolv.conf to disable network :</p>
  
  <p><strong><em>sudo mv /etc/resolv.conf    /etc/resolv_backup.conf<br>
  sudo touch /etc/resolv.conf</em></strong></p>
  
  <p>Then to enable network:</p>
  
  <p><strong><em>sudo mv /etc/resolv_backup.conf /etc/resolv.conf</em></strong></p>
  
  <p>However the resource is busy and I cannot execute these commands.</p>
  
  <p>I want to disable internet from within container and not using:</p>
  
  <p><em>docker network disconnect [OPTIONS] NETWORK CONTAINER</em></p>
  
  <p>which does this from server on which container is deployed.
  I am using Alpine.</p>
