Use the following script to update the geostreaming api to the latest **develop** branch. Update the name of the branch if you want to get the latest production one. I am not sure on how to get this file to puppet 


#!/bin/bash
GS3_BRANCH=${GS3_BRANCH:-"GEOD-GS0"}
GS3_BUILD=${GS3_BUILD:-"latestSuccessful"}
# Slack token for notifications
SLACK_TOKEN=**Get from other script**

# change to folder where script is installed
cd /home/clowder

# fetch software

Note: You need to have inside /home/clowder/geo-temporal-api-v3 a custom folder with the application.conf file and the messages.en 

There is a sample application.conf in seagrant-dev machine under Yan's username. 


If this is the first time deploying, remember the setting up steps for the region trend tables (if needed) and the parameters (needed for all). More details in Geostreams-api-v3 - Local 


Add to your nginx a route for /geostreams 


  rewrite ^/geostreams$ /geostreams/ permanent;

  location /geostreams {

    proxy_pass http://localhost:9002;

  }
