Retrieving external ip in .erb template

Gwenn Etourneau #118 Question, normally your kafka node will bind to all interface, so something like <%= spec.networks.yournetworks.ip%> should work no ? toggle quoted message Show quoted text On Wed, May 27, 2015 at 3:49 PM, Stevo Slavić <sslavic(a)gmail.com> wrote: Thanks for reply Dmitriy! I needed a script that gives me static vip of instance, one which does not change (without changes to deployment manifest). I tried and found out that spec.networks.marshal_dump.first[1].ip gives me elastic ip, not the static vip of instance. I'm worried, if templates get applied only during "bosh deploy", if events, other than "bosh deploy", are possible where elastic ip can change without templates being reevaluated, then advertised ip in configuration file will be stale/outdated, not in sync with actual elastic ip of vm, and kafka will not be reachable through advertised ip, but it will be accessible through static vip, resulting in all sorts of failures. So, is it possible that elastic ip changes without templates being reevaluated? If yes, then I need a way to determine instance static vip in configuration file template. Kind regards, Stevo Slavic.
