Using sling conns

Here are examples of setting a connection named AWS_S3. We must provide the type=s3 property:

$ sling conns set AWS_S3 type=s3 bucket=sling-bucket profile=my-profile

$ sling conns set AWS_S3 type=s3 bucket=sling-bucket access_key_id=ACCESS_KEY_ID secret_access_key="SECRET_ACCESS_KEY"

Environment Variable

See here to learn more about the .env.sling file.

In JSON/YAML format:

export AWS_S3='{type: s3, bucket: sling-bucket, access_key_id: ACCESS_KEY_ID, secret_access_key: "SECRET_ACCESS_KEY"}'

export AWS_S3='{type: s3, bucket: sling-bucket, profile: my-profile}'

# or via AWS classic environment variables
export AWS_ACCESS_KEY_ID='<aws_access_key_id>'
export AWS_SECRET_ACCESS_KEY='<aws_secret_access_key>'
export AWS_SESSION_TOKEN='<aws_session_token>'
