[jira] [Commented] (YARN-8619) Automate docker network configuration through YARN API

["Eric Yang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/YARN-8619?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16567558#comment-16567558 ] 

Eric Yang commented on YARN-8619:
---------------------------------

Each host may need to be configured differently, and using a file approach as parameter might be more scalable to support other type of network driver as well.  Therefore, we might use:
{code}
yarn network -create my-macvlan-net /tmp/network.json
{code}

Content of json looks like:
{code}
{
  "driver": "macvlan",
  "hosts": [
    {
      "name":"host1.example.com",
      "subnet": "172.16.86.0/24",
      "gateway": "172.16.86.1",
      "parent": "eth0"
    }
  ]
}
{code}

For listing networks:
{code}
yarn network -list
{code}

For destroy networks:
{code}
yarn network -destroy my-macvlan-net
{code}

> Docker supports bridge, host, overlay, macvlan networking.  It might be useful to automate docker network setup through a set of YARN API to improve management of docker networks.  Each type of network driver requires different type of parameters.  For Hadoop use case, it seems more useful to focus on macvlan networking for ease of use and configuration.  It would be great addition to support commands like:
> {code}
> yarn network create -d macvlan \
>   --subnet=172.16.86.0/24 \
>   --gateway=172.16.86.1 \
>   -o parent=eth0 \
>   my-macvlan-net
> {code}
> This changes docker configuration to hosts managed by YARN.
