Docker and S3 (or other storage) hosting with Privacy focus

Hi

I search for a Docker and S3 (or other storage) hosting with Privacy focus.

With DDG I found only big players.
I not wish a VM and install Docker Daemon myself

I suspect such service not exists?

Amazon S3 bucket works with Cryptomator

Use anything even google storage but encrypt data by GPG, AES or Cryptomator

I not search for private S3 storage

I wish to upload a docker image which will serve small web app with images stored in s3

What about Nextcloud? Nextcloud has a Docker image you can deploy in your own bare metal servers. However, I am not entirely sure how you can link it to an S3 bucket to make it seamless.

Does that satisfy your requirements?
