Benjamin Bannier created MESOS-7977:
---------------------------------------
Summary: Installation guide should call out that Mesos-managed
ports and system ephemeral ports should not overlap
Key: MESOS-7977
URL: https://issues.apache.org/jira/browse/MESOS-7977
Project: Mesos
Issue Type: Bug
Components: documentation
Reporter: Benjamin Bannier
Mesos agents do not make sure that the ports they manage do not overlap with
the host's ephemeral port range. This can lead to situations where tasks fail
since another process might have been assigned a port in that range when
binding to port 0.
We should strongly suggest administrators to remove Mesos-managed ports from
the ephemeral port range. This topic is currently only briefly mentioned in the
port mapping isolator documentation,
https://github.com/apache/mesos/blob/38cb694f55ec8ab69efa83e1b958eac071fee2d4/docs/port-mapping-isolator.md#L100-L114.
It would be great to make this a suggested part of the installation.
