Be careful on command: "kong migrations up"
Note for Kong < 0.15: with Kong versions below 0.15 (up to 0.14), use the up sub-command instead of bootstrap. Also note that with Kong < 0.15, migrations should never be run concurrently; only one Kong node should be performing migrations at a time. This limitation is lifted for Kong 0.15, 1.0, and above.

Two fixes which worked for me.

Env:
OS - Amazon linux
Kong images version - latest

  1. kong migrations up >> kong migrations bootstrap . (newer versions of kong as mentioned by @juarrosluis)
  2. In the section where you define your kong service and under environment key, add KONG_DATABASE: postgres alongwith KONG_PG_HOST.
