[jira] [Commented] (MESOS-5226) The image-less task launched by mesos-execute can not join CNI network

["Qian Zhang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MESOS-5226?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15245052#comment-15245052 ] 

Qian Zhang commented on MESOS-5226:
-----------------------------------

The root cause of this bug is, in {{CommandScheduler::getContainerInfo()}}, we will not return a {{ContainerInfo}} as long as there is no image specified even there is CNI network specified, instead we will just return {{None()}} in this case. And in {{NetworkCniIsolatorProcess::prepare()}}, we will just ignore the container which has no {{ContainerInfo}}, so any CNI related logic will not be applied to the executor which will be in agent host network namespace.

> With {{mesos-execute}}, if we launches a task which wants to join a CNI network but has no image specified, like:
> {code}
> sudo src/mesos-execute --master=192.168.122.171:5050 --name=test --networks=net1 --command="ifconfig" --shell=true
> {code}
> The corresponding command executor actually will not join the specified CNI network, instead it is still in agent host network namespace.
