Configure aws CLI for R2
You must generate an Access Key before getting started. All examples will utilize access_key_id and access_key_secret variables which represent the Access Key ID and Secret Access Key values you generated.
With the aws CLI installed, you may run aws configure to configure a new profile. You will be prompted with a series of questions for the new profile’s details.
$ aws configureAWS Access Key ID [None]: <access_key_id>AWS Secret Access Key [None]: <access_key_secret>Default region name [None]: autoDefault output format [None]: jsonYou may then use the aws CLI for any of your normal workflows.
$ aws s3api list-buckets --endpoint-url https://<accountid>.r2.cloudflarestorage.com

Generate presigned URLs
You can also generate presigned links which allow you to share public access to a file temporarily.
# You can pass the --expires-in flag to determine how long the presigned link is valid.
$ aws s3 presign --endpoint-url https://<accountid>.r2.cloudflarestorage.com s3://sdk-example/ferriswasm.png --expires-in 3600
