Starting more than 1 instance: data loading and database changes #687

Closed khandelwal closed 9 years ago

khandelwal commented 9 years ago

if we're starting more than one instance, we need to only have one of those instances do data loading and database changes.

I think we might be able to work around this issue by duplicating the app in the yaml file. The first only deploys one instance while updating the data and the second can deploy multiple instances, but doesn't update the database.

manifest file

---
# all applications use these settings and services
memory: 1G
instances: 1
applications:
- name: openfoia-staging
  path: .
  timeout: 180
  command: echo '---loading data---' & bash cf.sh
- name: openfoia-staging
  instances: 2
  path: .
  timeout: 180
  command: echo '---deploying---' & waitress-serve --port=$VCAP_APP_PORT foia_hub.wsgi:application

We solved a similar problem on FEC by using the CF_INSTANCE_INDEX https://github.com/18F/openFEC/blob/master/run_api.py
