Description

if command['roleCommand'] == 'INSTALL':
returncode, out, err = self.pull_image(command)
logger.info("docker pull result: " + str(returncode) + ";")
if command['roleCommand'] == 'START':
returncode, out, err = self.start_container(command)
return

{Constants.EXIT_CODE:returncode, 'stdout':out, 'stderr':err}

If user load image through tar file, it is available in local disk but not in remote repository or private repository. Slider agent should do a check before pulling
