+# `finallycoffee.services.minio` ansible role
+
+## Overview
+
+This role deploys a [min.io](https://min.io) server (s3-compatible object storage server)
+using the official docker container image.
+
+## Configuration
+
+The role requires setting the password for the `root` user (name can be changed by
+setting `minio_root_username`) in `minio_root_password`. That user has full control
+over the minio-server instance.
+
+### Useful config hints
+
+Most configuration is done by setting environment variables in
+`minio_container_extra_env`, for example:
+
+```yaml
+minio_container_extra_env:
+  # disable the "console" web browser UI
+  MINIO_BROWSER: off
+  # enable public prometheus metrics on `/minio/v2/metrics/cluster`
+  MINIO_PROMETHEUS_AUTH_TYPE: public
+```
+
+When serving minio (or any s3-compatible server) on a "subfolder",
+see https://docs.aws.amazon.com/AmazonS3/latest/userguide/RESTRedirect.html
+and https://docs.aws.amazon.com/AmazonS3/latest/userguide/VirtualHosting.html
