AWS S3

Lithops with AWS S3 as storage backend.

Configuration

Lithops automatically creates a bucket with a unique name for your user. If you want to use a different bucket, you can create it manually and provide the name in the lithops config file. For this:

1. Login to Amazon Web Services Console (or signup if you don’t have an account)

2. Navigate to S3 and create a bucket. Type a name (e.g. lithops-data-mysuer). The bucket should be created in the same region as the Lambda functions are expected to be run (mainly to avoid inter-region data transfer charges).

AWS Credential setup

Lithops loads AWS credentials as specified in the boto3 configuration guide.

In summary, you can use one of the following settings:

1. Provide the credentials via the ~/.aws/config file, or set the AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment variables.

   You can run aws configure command if the AWS CLI is installed to setup the credentials. Then set in the Lithops config file:

   lithops:
       storage: aws_s3
   
   aws:
       region: <REGION_NAME>
   

2. Provide the credentials in the aws section of the Lithops config file:

   lithops:
       storage: aws_s3
   
   aws:
       access_key_id: <AWS_ACCESS_KEY_ID>
       secret_access_key: <AWS_SECRET_ACCESS_KEY>
       region: <REGION_NAME>
