1. Managing S3 Object Versioning


    Versioning in Amazon S3 is a means of keeping multiple variants of an object in the same bucket. You can use it to recover objects from accidental deletion or overwrite. When you enable versioning on an S3 bucket, S3 will keep all versions of an object even if you delete or overwrite it. This allows you to restore a previous version at any time.

    To manage object versioning in Amazon S3 using Pulumi, you'll need to use the aws.s3.Bucket resource to create a new bucket or configure an existing one, and the aws.s3.BucketVersioning resource to enable or suspend versioning on that bucket.

    Here's a program in TypeScript that demonstrates how to do this:

    1. First, we'll create a new S3 bucket using the aws.s3.Bucket resource.
    2. Then, we'll enable versioning on this bucket using the aws.s3.BucketVersioning resource.

    Make sure you have Pulumi installed and configured with AWS credentials before running this program.

    import * as pulumi from "@pulumi/pulumi"; import * as aws from "@pulumi/aws"; // Create an AWS S3 bucket const myBucket = new aws.s3.Bucket("my-bucket", { // Optionally you can configure additional bucket settings here }); // Enable versioning on the above-created S3 bucket const myBucketVersioning = new aws.s3.BucketVersioning("my-bucket-versioning", { bucket: myBucket.id, // Reference the bucket created above versioningConfiguration: { status: "Enabled", // Set the versioning status to 'Enabled' }, }); // Export the name of the bucket export const bucketName = myBucket.bucket; // Export the versioning status export const versioningStatus = myBucketVersioning.versioningConfiguration.apply(v => v.status);

    In this program:

    • We import the necessary Pulumi and AWS SDK modules.
    • We create a new S3 bucket named my-bucket.
    • We then create a BucketVersioning resource, which references the bucket we created. We set the versioningConfiguration.status to "Enabled" to turn on versioning.
    • Lastly, we export the bucket name and the versioning status so that you can easily retrieve these values from the Pulumi stack outputs.

    To run this program:

    1. Save the code to a file with a .ts extension, for example, enableS3Versioning.ts.
    2. Run pulumi up in the command line from the directory where the file is located.
    3. Pulumi CLI will perform the deployment, and once completed, it will output the bucket name and versioning status.
