Lab 1 - From Zero to Pushing Your First Application

Target

If you haven’t already, download the latest release of the Cloud Foundry CLI from https://github.com/cloudfoundry/cli/releases for your operating system and install it.
Set the API target for the CLI: (set appropriate end point for your environment)
```
$ cf api https://api.pcf.centurylinkcloud.com --skip-ssl-validation
```
Login to Pivotal Cloudfoundry:
```
$ cf login
```
Follow the prompts

Push It!

Change to the nodejs-cf-sample-ap sample application directory:
```
$ cd $BOOTCAMP_HOME/nodejs-cf-sample-app
```

Push the application!

$ cf push

You should see output similar to the following listing. Take a look at the listing callouts for a play-by-play of what’s happening:

The CLI is using a manifest to provide necessary configuration details such as application name, memory to be allocated, and path to the application artifact. Take a look at manifest.yml to see how.
In most cases, the CLI indicates each Cloud Foundry API call as it happens. In this case, the CLI has created an application record for Workshop in your assigned space.
All HTTP/HTTPS requests to applications will flow through Cloud Foundry’s front-end router called (Go)Router. Here the CLI is creating a route with random word tokens inserted (again, see manifest.yml for a hint!) to prevent route collisions across the default devcloudwest.inbcu.com domain.
Now the CLI is binding the created route to the application. Routes can actually be bound to multiple applications to support techniques such as blue-green deployments.
The CLI finally uploads the application bits to Pivotal Cloud Foundry. Notice that it’s uploading 39 files! This is because Cloud Foundry actually explodes a ZIP artifact before uploading it for caching purposes.
Now we begin the staging process.
Node and NPM dependenices are pulled from git hub, normally they would be pulled from Cloud Foundry, this is specific to Node.
Here we see the version of the 'express@4.12.4 node_modules/express' that has been chosen and installed.
Here we see the version of the 'njade@1.11.0 node_modules/jade' that has been chosen and installed.
Here we see the version of the 'bower@1.5.3 node_modules/bower' that has been chosen and installed.
The complete package of your application and all of its necessary runtime components is called a droplet. Here the droplet is being uploaded to Pivotal Cloudfoundry’s internal blobstore so that it can be easily copied to one or more Droplet Execution Agents (DEA’s) for execution.
The CLI tells you exactly what command and argument set was used to start your application.
Finally the CLI reports the current status of your application’s health.

Visit the application in your browser by hitting the route that was generated by the CLI:
