Serverless URL Shortener with Redis Cache

A sample URL shortener SPA that uses the high-level cloud.Table and cloud.API components. The example shows to combine serverless functions along with containers. This shows that you can create your own cloud.*-like abstractions for your own use, your team's, or to share with the community using your language's package manager.

Deploying and running the program

Note: some values in this example will be different from run to run. These values are indicated with ***.

1. Create a new stack:

   $ pulumi stack init url-cache-testing
   

2. Set AWS as the provider:

   $ pulumi config set cloud:provider aws
   

3. Configure Pulumi to use AWS Fargate, which is currently only available in us-east-1, us-east-2, us-west-2, and eu-west-1:

   $ pulumi config set aws:region us-west-2
   $ pulumi config set cloud-aws:useFargate true
   

4. Set a value for the Redis password. The value can be an encrypted secret, specified with the --secret flag. If this flag is not provided, the value will be saved as plaintext in Pulumi.url-cache-testing.yaml (since url-cache-testing is the current stack name).

   $ pulumi config set --secret redisPassword S3cr37Password
   

5. Restore NPM modules via npm install or yarn install.

6. Preview and run the deployment via pulumi up. The operation will take about 5 minutes to complete.

   $ pulumi up
   Previewing stack 'url-cache-testing'
   ...
   
   Updating stack 'url-cache-testing'
   Performing changes:
   
   #:  Resource Type                            Name
   1:  pulumi:pulumi:Stack                      url-shortener-cache-url-
   ...
   49: aws:apigateway:Stage                     urlshortener
   
   info: 49 changes performed:
       + 49 resources created
   Update duration: ***
   

7. To view the API endpoint, use the stack output command:

   $ pulumi stack output endpointUrl
   https://***.us-east-1.amazonaws.com/stage/
   

8. Open this page in a browser and you'll see a single page app for creating and viewing short URLs.

Clean up

To clean up resources, run pulumi destroy and answer the confirmation question at the prompt.
