----------------------------------
Summary: 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
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.
