Chen He commented on SLIDER-919:
--------------------------------
Hi [~thomas_liu], what you mean "migrating this to YARN"?
DockerContainerExecutor currently assumes image is ready in local disk before
starting. Thanks.
> Slider DockerManager should check whether image is available locally before
> pull from repository

> 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)
> # need check
> 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
