aws-ts-apigateway

Serverless REST API

A simple REST API that counts the number of times a route has been hit. For a detailed walkthrough of this example, see the article Create a Serverless REST API.

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 count-api-testing

2. Set the AWS region:

   $ pulumi config set aws:region us-east-2
   

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

4. Run pulumi up to preview and deploy changes:

   $ pulumi up
   Previewing update of stack 'count-api-testing'
   ...
   
   Updating (count-api-testing):
   
        Type                                Name                                 Status
    +   pulumi:pulumi:Stack                 aws-ts-apigateway-count-api-testing  created
    +   ├─ aws:apigateway:x:API             hello-world                          created
    +   │  ├─ aws:iam:Role                  hello-world4fcc7b60                  created
    +   │  ├─ aws:iam:RolePolicyAttachment  hello-world4fcc7b60-32be53a2         created
    +   │  ├─ aws:lambda:Function           hello-world4fcc7b60                  created
    +   │  ├─ aws:apigateway:RestApi        hello-world                          created
    +   │  ├─ aws:apigateway:Deployment     hello-world                          created
    +   │  ├─ aws:lambda:Permission         hello-world-a552609d                 created
    +   │  └─ aws:apigateway:Stage          hello-world                          created
    +   └─ aws:dynamodb:Table               counterTable                         created
   
   Outputs:
       endpoint: "https://***execute-api.us-east-2.amazonaws.com/stage/"
   
   Resources:
       + 10 created
   
   Duration: 24s
   

5. View the endpoint URL and curl a few routes:

   $ pulumi stack output
   Current stack outputs (1):
       OUTPUT            VALUE
       endpoint          https://***.us-east-2.amazonaws.com/stage/
   
   $ curl $(pulumi stack output endpoint)/hello
   {"route":"hello","count":1}
   $ curl $(pulumi stack output endpoint)/hello
   {"route":"hello","count":2}
   $ curl $(pulumi stack output endpoint)/woohoo
   {"route":"woohoo","count":1}

6. To view the runtime logs of the Lambda function, use the pulumi logs command. To get a log stream, use pulumi logs --follow.

Clean up

1. Run pulumi destroy to tear down all resources.

2. To delete the stack itself, run pulumi stack rm. Note that this command deletes all deployment history from the Pulumi console.
