----------------------------------
Assignee: Sha Zhengju
> Network portmapping isolator disable IPv6 failed
> ------------------------------------------------
>
> Key: MESOS-5381
> URL: https://issues.apache.org/jira/browse/MESOS-5381
> Project: Mesos
> Issue Type: Bug
> Components: isolation
> Environment: CentOS7
> Reporter: Sha Zhengju
> Assignee: Sha Zhengju
>
> We observed this error in our environment:
> 1. enable --isolation=network/port_mapping for mesos 0.28.0 on CentOS7.2
> with kernel version: 3.10.0-327.10.1.el7.x86_64
> 2. create simple application on marathon framework with commands such as
> "echo hello"
> 3. mesos executor failed with error logs in sandbox stderr file:
> {quote}
> + mount --make-rslave /var/run/netns
> + echo 1
> sh: line 3: /proc/sys/net/ipv6/conf/all/disable_ipv6: No such file or
> directory Failed to execute a preparation shell command
> {quote}
> The reason is that we should do some ipv6 check in
> isolators/network/port_mapping.cpp:PortMappingIsolatorProcess::scripts(), if
> ipv6 module is not loaded while kernel booting(such as in CentOS7/RHEL7), we
> don't need to disable ipv6 anymore.
