commit d02d66043e2beedbb7cd1c1bbf78ce8d506d82b7
Author: Benno Evers <[email protected]>
Date: Tue Jan 2 10:58:35 2018 -0800
Added a master flag to disallow agents without domain.
Added a new `--require_agent_domain` flag and implementation. When
set to true, it will cause the master to refuse (re-)registration
attempts for agents with no configured domain.
This is intended as a safety net for operators, who could forget to
configure the fault domain of a remote agent and let it join the
cluster. If this happens, an agent in a remote region will be
considered a local agent by the master and frameworks (because agent's
fault domain is not configured), causing tasks to potentially land in a
remote agent which is undesirable.

> Project: Mesos
> Issue Type: Improvement
> Reporter: Vinod Kone
> Assignee: Benno Evers
> Fix For: 1.5.0, 1.5.1
>
>
> Once mesos masters and agents in a cluster are *all* upgraded to a version
> where the fault domains feature is available, it is beneficial to enforce
> that agents without a fault domain configured are not allowed to join the
> cluster.
> This is a safety net for operators who could forget to configure the fault
> domain of a remote agent and let it join the cluster. If this happens, an
> agent in a remote region will be considered a local agent by the master and
> frameworks (because agent's fault domain is not configured) causing tasks to
> potentially land in a remote agent which is undesirable.
> Note that this has to be a configurable flag and not enforced by default
> because otherwise upgrades from a fault domain non-configured cluster to a
> configured cluster will not be possible.
