At the moment every S3Proxy client has to hold a long-lived access key and secret, and each key gets full access to whatever its backend can reach. I have a use case that would benefit from short-lived, scoped-down credentials on the same S3Proxy instance. The rough idea is similar to Cloudflare R2's temporary credentials. A holder of a configured key mints a session token signed with the parent key's secret. The token encodes the allowed actions, the prefixes or object keys it's limited to, and an expiry. The client keeps the parent access key ID, uses HMAC(parent_secret, token) as its secret access key, and sends the token in X-Amz-Security-Token. S3Proxy checks the token, derives the secret again to check the signature, and enforces the scope before calling the backend. Is there any appetite for something like this from the maintainers? I'm happy to adjust the design to your preferences.
The Docker image currently runs everything as root. With #401 complete (jlink-trimmed JRE, #993), the remaining obvious hardening gap is dropping root: container scanners flag it (CIS Docker Benchmark 4.1), and the Kubernetes restricted Pod Security Standard rejects root images unless deployments override runAsUser. Non-root was deliberately deferred from the #993 review as out of scope, and it changes long-standing defaults, so filing this to collect feedback before committing to an approach. Current behavior dumb-init, run-docker-container.sh, and java all run as uid 0. The default S3PROXY_ENDPOINT=http://0.0.0.0:80 binds a privileged port. The run script creates JCLOUDS_FILESYSTEM_BASEDIR (default /data) at startup, which works only because root may create directories under /. Proposal Create a dedicated s3proxy user and group with a fixed, documented uid/gid and add a numeric USER <uid>:<gid> (numeric so Kubernetes runAsNonRoot validates without an explicit runAsUser).

Add support for creating traces for each storage (proxy) request and allow users to publish them to an OTel exporter.
Docker hub page seems to have some small issues on tag consistency. Images are not labeled as "latest" and no versioning is in place. Could use some automated tags based on release from github.
