Hey all, does anyone have some simple code that checks for the existence of a S3 bucket before attempting to create a new one? Or some Pulumi config that skips over a call to

new aws.s3.Bucket

if it exists when running

pulumi up

?

I don’t have sample code for you, but I’m tempted to say you should be able to use “get” to lookup a bucket, and skip creating if the get is successful. https://www.pulumi.com/registry/packages/aws/api-docs/s3/bucketobject/#look-up

Thanks. I ended up using aws.s3.getBucket to check for bucket existence in the end, similar to BucketObject. Cheers.

This isn't the normal pattern for achieving this in Pulumi. If you want to have a bucket managed by Pulumi, then the if-already-exists logic should be handled manually, once. The resource would be imported (via

pulumi import

or by adding the import ID to the resource opts) if it exists, and not imported if it doesn't. This avoids conditional code that should run only once.
