Azure Cosmos DB, an API Connection, and a Logic App

View Code

With the native Azure provider we can directly use the Azure resource manager API to define API connections and linking it to a logic app. The resulting experience is much faster in comparison to performing the same operation through ARM templates.

Prerequisites

• Node.js
• Download and install the Pulumi CLI
• Connect Pulumi with your Azure account (if your az CLI is configured, no further changes are required)

Running the App

1. Create a new stack:

   $ pulumi stack init dev
   

2. Set the required configuration variables for this program, and log into Azure:

   $ pulumi config set azure-native:location westeurope
   $ az login
   

3. Perform the deployment:

   $ pulumi up
   
        Type                                                Name                         Status
    +   pulumi:pulumi:Stack                                 azure-cosmosdb-logicapp-dev  created
    +   ├─ azure-native:resources:ResourceGroup             logicappdemo-rg              created
    +   ├─ azure-native:storage:StorageAccount              logicappdemosa               created
    +   ├─ azure-native:documentdb:DatabaseAccount          logicappdemo-cdb             created
    +   ├─ azure-native:documentdb:SqlResourceSqlDatabase   db                           created
    +   ├─ azure-native:web:Connection                      cosmosdbConnection           created
    +   ├─ azure-native:documentdb:SqlResourceSqlContainer  container                    created
    +   └─ azure-native:logic:Workflow                      workflow                     created
   
   Resources:
       + 8 created
   
   Duration: 3m16s
   

4. At this point, you have a Cosmos DB collection and a Logic App listening to HTTP requests. You can trigger the Logic App with a curl command:

   $ curl -X POST "$(pulumi stack output endpoint)" -d '"Hello World"' -H 'Content-Type: application/json'
   

   The POST body will be saved into a new document in the Cosmos DB collection.

5. Once you are done, you can destroy all of the resources, and the stack:

   $ pulumi destroy
   $ pulumi stack rm
