Re: dynamic networks

That other thread Rob and Alvaro just mentioned currently leaves open the
question of why metron_agent worked when deployed from Micro BOSH on
stemcell 3160 but started giving this error message on 3163. For sanity, I
wlll continue the discussion on that other thread.

As Amit wrote in the other, related thread -

This will not work with dynamic networks. Many jobs in cf-release rely
on data from BOSH to determine their IP so that configuration files can be
rendered up-front by the director rather than at runtime, requiring system
calls to determine IP. metron_agent is one such job, and it tends to be
colocated with each other job (it is what allows all system component logs
to be aggregated through the loggregator system), so this would require all
Cloud Foundry VMs to be on a manual network. You don't need to manually
pick the IPs, you just need to tell BOSH which IPs in the network not to
use and specify these in the "reserved" range.

Since so many different components depend on being able to determine
their IP via BOSH data, there's no quick workaround if you want to stick to
using dynamic networks, but we're aware of this current limitation.
