What is the process for utilizing Vercel alongside Amazon DocumentDB and Pulumi in Go

Question

Pulumi · Accepted Answer

To utilize Vercel alongside Amazon DocumentDB with Pulumi in Go, you will need to perform the following steps:

Set up Vercel for deployment: Define a Vercel project to handle the deployment of your front-end or serverless functions. Use the vercel.Project and vercel.Deployment resources.
Configure Amazon DocumentDB: Define an AWS DocumentDB cluster instance to store your application data. Use the aws.docdb.ClusterInstance resource.
Connect the two services: Ensure your Vercel deployment can connect to the DocumentDB instance. You might need to set environment variables in your Vercel project that hold the connection details to the DocumentDB.
Write the Pulumi program: Implement these resources in a Go program and deploy using the pulumi up command.

Here's a Pulumi program in Go that accomplishes the above steps:

package main

import (
	"github.com/pulumi/pulumi-aws/sdk/v6/go/aws/docdb"
	"github.com/pulumi/pulumi/sdk/v3/go/pulumi"
	"github.com/pulumiverse/pulumi-vercel/sdk/go/vercel"
)

func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {
		// Create a Vercel Project
		project, err := vercel.NewProject(ctx, "myVercelProject", &vercel.ProjectArgs{
			// Fill in the project details according to your Vercel setup
			Name:  pulumi.String("my-vercel-project"),
			TeamId: pulumi.String("<my-vercel-team-id>"),
		})
		if err != nil {
			return err
		}

		// Create an AWS DocumentDB Cluster Instance
		docDb, err := docdb.NewClusterInstance(ctx, "myDocDbInstance", &docdb.ClusterInstanceArgs{
			InstanceClass:     pulumi.String("db.r4.large"),
			ClusterIdentifier: pulumi.String("<my-docdb-cluster-identifier>"),
			Engine:            pulumi.String("docdb"),
			// Make sure to set these parameters according to your specific requirements
		})
		if err != nil {
			return err
		}

		// Set up an Alias for the Vercel deployment
		vercelAlias, err := vercel.NewAlias(ctx, "myVercelAlias", &vercel.AliasArgs{
			Alias:        pulumi.String("<your-domain.com>"),
			TeamId:       pulumi.String("<my-vercel-team-id>"),
			DeploymentId: project.Id, // Linking to the 'myVercelProject'
		})
		if err != nil {
			return err
		}

		// Export the URL and the DocumentDB Cluster Instance Address
		ctx.Export("vercelUrl", vercelAlias.Alias)
		ctx.Export("docDbAddress", docDb.Address)

		return nil
	})
}

Explanation:

The vercel.NewProject creates a new project on Vercel with the specified configuration. Replace the placeholders with your actual Vercel team ID and desired project name.
The docdb.NewClusterInstance creates a new DocumentDB cluster instance on AWS. You must replace the placeholders with your actual desired instance class and the identifier for your DocumentDB cluster. Please set additional properties according to your requirements.
The vercel.NewAlias sets up an alias to link your deployment to a domain.
Lastly, we export the Vercel URL and the DocumentDB instance address so you can use them in your application or for reference.

Please note that this example assumes that you have configured your AWS and Vercel credentials. Also, replace placeholders with actual values required by your project, such as cluster identifier, instance class, domain, etc. To run this program, save it to a file, navigate to the directory in the terminal, and execute pulumi up.

It's crucial to ensure that network connectivity (like VPC peering, Vercel Environment Variables for connecting to DocumentDB) between Vercel and DocumentDB is configured correctly for them to communicate securely. This usually involves allowing access to the DocumentDB from Vercel deployed application IP addresses and providing connection strings via environment variables or Vercel project settings, which was not detailed here due to its dependency on specific project details and security considerations.
