> Key: SLIDER-1232
> URL: https://issues.apache.org/jira/browse/SLIDER-1232
> Project: Slider
> Issue Type: Bug
> Components: agent-provider
> Affects Versions: Slider 0.91, Slider 0.92
> Reporter: ouchengeng
> Assignee: ouchengeng
> Priority: Critical
> Fix For: Slider 0.92

> Attachments: SLIDER-1232.patch

>
> When apps are docker containers, agentProviderService can tell slider-agent
> this is a docker mode, so DockerManager.py can install/start docker
> containers.
> However, as for stop_command, provider fails to tell this is in docker mode,
> that is to say missing docker entry in command.
> This will cause following exceptions.
> ```
> ERROR 2017-07-05 05:14:25,830 CustomServiceOrchestrator.py:169 - Caught an
> exception while executing command: <type 'exceptions.AttributeError'>:

> In AgentProviderService.java, I find that there are
> addInstallCommand/addInstallDockerCommand,
> addStartCommand/addStartDockerCommand methods. However, stop method for
> docker is missing. That's why slider-agent/ActionQueue.py cannot recognize
> this command properly and causes above exception.
