title: sbin/start-stop-daemon not able to start python - ubuntu docker container
body: <p>I have a simple python script which I want to start a daemon-service in background in docker container</p>
  
  <pre><code>/sbin/start-stop-daemon --start  --user root --make-pidfile --pidfile /var/lock/subsys/my-application.pid --exec 'python /opt/app/uc/monitor/bin/my-application.py'
  </code></pre>
  
  <p>when I execute this command in a shell I get </p>
  
  <pre><code>/sbin/start-stop-daemon: unable to stat //python /opt/app/uc/monitor/bin/my-application.py (No such file or directory)
  </code></pre>
  
  <p>However when execute just the below command in shell it works </p>
  
  <pre><code>python /opt/app/uc/monitor/bin/my-application.py 
  </code></pre>
  
  <p>I'm sure the python is installed and all the links have been setup. </p>
  
  <p>Thanks for the help</p>
