VariableS3_STORAGE_ACCESSKEY
DescriptionSets the access key for S3 storage

Bucket storage (S3 variant. For Google variant, replace "S3" with "GCP" in all the following keys.) - infinite storage using local disks as cache. See the page on Bucket Storage for more information. These two take precedence over all other AWS access methods.

ini files
S3_STORAGE_ACCESSKEY=$ACCESS_KEY
S3_STORAGE_SECRETKEY=$SECRET_KEY
S3_STORAGE_ENCRYPTION_KEY=$ENCRYPTION_SECRET

Also supported, are AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY. The third option here is to set the encryption key, which can be any UTF-8 string. The suggested value is 64 or more random ASCII characters.

You could instead point to your own hosting endpoint for the S3 to use for storage. To use a non-AWS endpoint with the S3_STORAGE_ENDPOINT_BASE, setting it to the URL (e.g., http://my-own-s3:8080).
