nikhilsuvarna / get-instance-guid
Created December 27, 2016 15:25
proper way of getting instance guid from diego
get the app guid, query CC to construct the process guid from app-guid+app-version
[11:22]
query the BBS API for the actual lrps for that process guid (and index, if you care)
[11:22]
which will get you the cell id and instance guid for each actual lrp
[11:23]
and then go to that cell and get into the container for that instance guid

bosh2 stuff

v1 vs v2 https://bosh.io/docs/cli-v2-diff.html

bosh2 is strict about SSL certs. If a director has been initialized using bosh1 cli, connecting to the director via bosh2 cli will throw the folowing error :

ubuntu@bosh-stemcell:~$ bosh2 alias-env dev -e 10.193.72.9
