Allen Wittenauer commented on YARN-3988:
----------------------------------------
It's a bit of a security hole to let users dictate docker run params....
> DockerContainerExecutor should allow user specify "docker run" parameters
> -------------------------------------------------------------------------
>
> Key: YARN-3988
> URL: https://issues.apache.org/jira/browse/YARN-3988
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: nodemanager
> Affects Versions: 2.7.1
> Reporter: Chen He
> Assignee: Chen He
>
> In current DockerContainerExecutor, the "docker run" command has fixed
> parameters:
> String commandStr = commands.append(dockerExecutor)
> .append(" ")
> .append("run")
> .append(" ")
> .append("--rm --net=host")
> .append(" ")
> .append(" --name " + containerIdStr)
> .append(localDirMount)
> .append(logDirMount)
> .append(containerWorkDirMount)
> .append(" ")
> .append(containerImageName)
> .toString();
> For example, it is not flexible if users want to start a docker container
> with attaching extra volume(s) and other "docker run" parameters.
