Subject [jira] [Commented] (YARN-1964) Create Docker analog of the LinuxContainerExecutor in YARN
Date Fri, 12 Sep 2014 15:01:34 GMT

    [ https://issues.apache.org/jira/browse/YARN-1964?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14131640#comment-14131640
] 

Abin Shahab commented on YARN-1964:
-----------------------------------

We have decided to create an umbrella issue to cover the integration between YARN and Docker(YARN-2466).

This task(YARN-1964) has the following scope:
1) Launch docker containers from YARN with net=host mode. This will allow the container to
take on the host's network, and therefore the YARN administrators will not need to set up
special networking for docker.
2) Allow users to provide docker images through the job configuration.
3) Setup and user guides.

The rest(secure hadoop, advanced networking) will be handled in other issues under YARN-2466.

Please add your feedback to this plan on this jira.
Thanks!
Abin

> Docker (https://www.docker.io/) is, increasingly, a very popular container technology.
> In context of YARN, the support for Docker will provide a very elegant solution to allow
applications to *package* their software into a Docker container (entire Linux file system
incl. custom versions of perl, python etc.) and use it as a blueprint to launch all their
YARN containers with requisite software environment. This provides both consistency (all YARN
containers will have the same software environment) and isolation (no interference with whatever
is installed on the physical machine).
