Creating and Deploying a Simple Web App to Cloud Foundry

To create and deploy a simple web application, you can clone a copy of the Predix Hello World web application and deploy it to Cloud Foundry.

Procedure

Use the Cloud Foundry CLI to log into Cloud Foundry.
```
cf login -a <API_Endpoint>
```
Note: If you are a GE employee, you must use the cf login --sso command to log into Cloud Foundry. After you enter your SSO, you will receive a one-time passcode URL. Copy this URL and paste it in a browser to retrieve your one-time passcode. Use this code with the cf command to complete the CF login process.

Depending on your Predix.io registration, the value of <API_Endpoint> is one of the following:
- Predix US-West
  https://api.system.aws-usw02-pr.ice.predix.io
- Predix Europe
  https://api.system.aws-eu-central-1-pr.ice.predix.io
For example,
```
cf login -a https://api.system.aws-usw02-pr.ice.predix.io
```

Clone a copy of the Predix Hello World web app to create a Predix Hello World project. At the command prompt, enter:

git clone https://github.com/PredixDev/Predix-HelloWorld-WebApp

The command produces the following output:

Unpacking objects: 100% (7/7),

Edit the manifest.yml file in the Predix-HelloWorld-WebApp directory to update the name of the web app to Predix-HelloWorld-WebApp-<YourAppName>. For example:

# 
applications:
  - name:
      Predix-HelloWorld-WebApp-<YourAppName>   
    buildpack: predix_openresty_buildpack
    #path: dist
    memory: 64M
    stack: cflinuxfs2

Make sure that you are in the Predix-HelloWorld-WebApp directory. From the directory, push your Predix web application to Cloud Foundry. At the command prompt, enter:
```
cf push
```
See your web app listed in your Cloud Foundry space:
```
cf apps
```
Enter your web app URL in a browser, including your app name, using HTTPS. For example:
```
 https://Predix-HelloWorld-WebApp-<YourAppName>.run.aws-usw02-pr.ice.predix.io
```
Your Predix Hello World web app displays in the web browser.
