Taking a look at Google Cloud APIsProgramming with Java

Part Five

Keeping Track – List of APIs

Some of the GCE OAuth Playground APIs

Understand OAuth 2.0 – what are scopes?

Specific levels of service access

Available scope options vary by service type

Google Cloud Storage has

read-only write_only read-write full-control

Google Compute Engine has

compute compute.readonly

Trying out the OAuth Playground

DEMO

Prepare to Program on the Google Cloud

• GAE, GCE, etc…• Download & Install

Google Cloud SDK

• Java (Eclipse)

Google Cloud

plug-in for IDE

• GWT tools (optional)• Android tools (optional)

Other Google

Web API tools

• MySQL ClientOther Tools

Download SDK

Configure Eclipse for Google Cloud

Get Cloud SDK Get Eclipse Plug-in

Start Programming

Create a new web app project Add Google APIs Write Code Run locally Deploy (ex. push to GAE)

Adding the service SDK tools via Eclipse

Running Locally

Using the Java API with GCE

DEMO

How does Authentication work? – GCE example

• This is token-based authentication

GCE uses ONLY OAuth 2.0

• Scope means ‘level of access’

• For GCE methods scope is either • Compute with read

and write –or-• Compute with read-

only• You may also need to

scope for Google Cloud Storage• This is called

‘devstorage’

OAuth requests have a

particular scope

• Can vary scope for these accounts• Compute

Engine• Console

ServiceGCE supports

creation of service

accounts

Using the Java API with Big Query

DEMO

Viewing Deployed Applications

Create up to 10 applications Click application to view detailed information

about each instance Can try out ‘push-to-deploy’
