• NPM Version: v6.4.1
• PCC Version: v1.4.0
• Pivotal GemFire: v9.3.0
• Pivotal GemFire Native Client Version: v9.2.1

Steps for Building the NodeJS App

1. Clone the git repo on Ubuntu workstation

   git clone https://github.com/nchandrappa/pad-pcc-pizzastore-nodejs-app.git
   

2. Download the Pivotal GemFire Native Client v9.2.1 and extract the tar file into

   /pad-pcc-pizzastore-nodejs-app/lib/

   https://network.pivotal.io/products/pivotal-gemfire/#/releases/163130

3. Set the following environment variables on ubuntu workstation

   export GFCPP=<dir>/pad-pcc-pizzastore-nodejs-app/lib/pivotal-gemfire-native
   export PATH=$PATH:$GFCPP/bin
   export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$GFCPP/lib
   

4. Npm install dependencies required for PCC client

   npm install node-pre-gyp --save
   npm install gemfire --save
   

Create PCC Instance

Services can be created through Apps Manager Marketplace or by executing cf cli commands

Display available PCC plans

cf marketplace p-cloudcache

Step 1: create a PCC OnDemand service in your org & space

cf create-service p-cloudcache extra-small pcc-dev-cluster

Step 2: Create service key for retrieving connection information for GFSH cli

cf create-service-key workshop-pcc devkey

Step 3: Retrieve url for PCC cli (GFSH) and corresponding credentials

cf service-key workshop-pcc devkey

Step 4: Login into to PCC cli (GFSH)

gfsh> connect --use-http=true --url=http://gemfire-xxxx-xxx-xx-xxxx.system.excelsiorcloud.com/gemfire/v1 --user=cluster_operator_xyz --password=*******

Step 5: create PCC regions

Note: Region name created on PCC server and client should match

gfsh> create region --name=pizza --type=PARTITION_REDUNDANT_PERSISTENT

Deploy NodeJS app on PCF

Step 1: Update the manifest.yml to reflect PCC instance created from the earlier steps
