Subject [jira] [Commented] (MESOS-5578) Support static address allocation in CNI
Date Fri, 10 Jun 2016 02:47:20 GMT

    [ https://issues.apache.org/jira/browse/MESOS-5578?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15323767#comment-15323767

Avinash Sridharan commented on MESOS-5578:
------------------------------------------

Good point.

The only catch is that if blindly specify the `ipaddress` in the CNI_ARGS it becomes a de-facto
standard that any other plugin that supports static IP address allocation will require to
follow to. Would like to have this specified in the spec so that we don't have to do plugin
specific support.

> Currently a framework can't specify a static IP address for the container when using
the network/cni isolator.
> The `ipaddress` field in the `NetworkInfo` protobuf was designed for this specific purpose
but since the CNI spec does not specify a means to allocate an IP address to the container
the `network/cni` isolator cannot honor this field even when it is filled in by the framework.
> Creating this ticket to act as a place holder to track this limitation. As and when the
CNI spec allows us to specify a static IP address for the container, we can resolve this ticket.
