MinIO Server - Docker Compose & NGINX reverse proxy

My basic example for a MinIO server.

⚠️ I'm leaving this up for historical reasons, but might be out of date as I am no longer relying on MinIO ⚠️

Docker Compose

version: '3'

services:
    minio:
        image: minio/minio:latest
        volumes:
            - /data/my-fancy-local-storage:/data
        ports:
        	# I use an NGINX reverse proxy, so these ports are only exposed
            # to the loopback adapter on the host server.
            - "127.0.0.1:9000:9000"
            - "127.0.0.1:9001:9001"
        environment:
            MINIO_ROOT_USER: <REDACTED>
            MINIO_ROOT_PASSWORD: <REDACTED>
            MINIO_SERVER_URL: https://s3.example.com
            MINIO_BROWSER_REDIRECT_URL: https://s3-manage.example.com
            MINIO_DOMAIN: s3.example.com
        command: server --console-address :9001 /data
        healthcheck:
            test: ["CMD", "curl", "-f", "http://minio:9000/minio/health/live"]
            interval: 1m30s
            timeout: 20s
            retries: 3
            start_period: 3m
        restart: unless-stopped

NGINX - Management console

Slightly tweaked as I use a lot of alias configs. This variant is conslidated into a singular configuration.
