Thanks for the advice. I think it would be even nicer if the HMAC credentials could be assigned to a specific bucket via an ACL. I like GCS (and the gsutil tool) but occasionally a S3 style bucket is needed. For example you need a S3 bucket or a webdav server in order to send alerts with images from Grafana to Slack. A minor issue but nice to have if possible without having to deal with Amazon's control panel.
