Digital Ocean Spaces (S3) "unable to sign request without credentials set"

I removed the commenting to make it live…

EDIT: I just realized that this has a typo in that last line. Not sure how I messed that up.

I saved and tried to rebuild and I get this…

That security warning was a new one. I ran to hopefully resolve that…

chmod o-rwx containers/app.yml

I verified the docker version…

docker --version

Looking in to how to update that. I thought rebuilding it would update that, but maybe not.
