From e04fd6fa1f0abe6b18787b192e01164db1db06db Mon Sep 17 00:00:00 2001 From: Kiran Kamineni Date: Thu, 18 Jul 2019 14:11:11 -0700 Subject: Add a list api for instances curl -X GET /v1/instance returns all the instances created. It returns abbreviated instances for improved readability. For details on what resources were created for each instance, use the ID with GET.
