-----------------------------
Summary: Port mapper CNI plugin might fail with "Resource
temporarily unavailable"
Key: MESOS-9125
URL: https://issues.apache.org/jira/browse/MESOS-9125
Project: Mesos
Issue Type: Bug
Components: network
Affects Versions: 1.6.1, 1.5.1, 1.4.1
Reporter: Jie Yu
https://github.com/apache/mesos/blob/master/src/slave/containerizer/mesos/isolators/network/cni/plugins/port_mapper/port_mapper.cpp#L345
Looks like we're missing a `-w` for the iptable command. This will lead to
issues like
{noformat}
The CNI plugin
'/opt/mesosphere/active/mesos/libexec/mesos/mesos-cni-port-mapper' failed to
attach container a710dc89-7b22-493b-b8bb-fb80a99d5321 to CNI network
'mesos-bridge': stdout='{"cniVersion":"0.3.0","code":103,"msg":"Failed to add
DNAT rule with tag: Resource temporarily unavailable"}
{noformat}
This becomes more likely if there are many concurrent launches of Mesos
contianers that uses port mapper on the box.
