Creating a Bucket with aws s3 mb

When you need somewhere to put files, use aws s3 mb. Short for "make bucket," it creates a new S3 bucket.

The syntax is aws s3 mb s3://bucket-name. The bucket is created in your default region unless you say otherwise.

Running aws s3 mb s3://my-bucket creates the bucket and prints make_bucket: my-bucket.

A common stumble is a name collision, because bucket names are globally unique. Including your project or organisation name usually avoids it.

In real work, buckets are created per purpose and environment — assets, backups, staging, production — rather than one bucket for everything.
