# MinIO

## Description

**MinIO** is an S3-compatible object storage service for files, media, backups, and AI artifacts, self-hosted for performance and control.

## Overview

Applications that speak “S3” (Pixelfed, Mastodon, Nextcloud, Flowise, etc.) store and retrieve objects from MinIO buckets using familiar SDKs and CLIs. Admins manage buckets, users, and access policies through a browser console while keeping everything on-prem.

## Cosmos

The diagram places MinIO in the Infinito.Nexus cosmos: the components it deploys (capabilities), the central services it consumes (dependencies), and its outward reach (federation and bridged external networks).

Solid `1:1` edges are fixed relationships; dashed `0..1` edges are conditional (enabled only in matching deployments); red `0..0` edges are turned off in this role. Node markers show the role's deploy modes (💻 host, 🐳 compose, 🐝 swarm); ❌ marks a service that is explicitly turned off, and ⚙️ an Ansible role dependency declared in `meta/main.yml`.

## Features

- S3-compatible API for broad app compatibility
- Buckets, users, access keys, and fine-grained policies
- Optional versioning, lifecycle rules, and object lock
- Presigned URLs for secure, time-limited uploads/downloads
- Ideal for AI stacks: datasets, embeddings, and artifacts

## Quick Setup

### Development

Clone, set up the workstation, and deploy MinIO onto the local stack:

```bash
git clone https://github.com/infinito-nexus/core.git
cd core
make onboard
make compose-deploy mode=reinstall apps=web-app-minio full_cycle=false
```

### Production

Run the published image to provision the inventory and deploy MinIO to a managed server (the mounted volume persists the inventory):

```bash
APP=web-app-minio
HOST=<your-server>
DOMAIN=<your-domain>
TLS_MODE=self_signed
SSH_PUBLIC_KEY="<your-ssh-public-key>"

docker run --rm -it \
  -v "$PWD/inventories:/etc/infinito.nexus/inventories" \
  -e APP="$APP" -e HOST="$HOST" -e DOMAIN="$DOMAIN" -e TLS_MODE="$TLS_MODE" -e SSH_PUBLIC_KEY="$SSH_PUBLIC_KEY" \
  ghcr.io/infinito-nexus/core/debian bash -c '
    INVENTORY=/etc/infinito.nexus/inventories/production
    infinito administration inventory provision "$INVENTORY" \
      --inventory-file "$INVENTORY/devices.yml" \
      --host "$HOST" \
      --include "$APP" \
      --vars "{\"TLS_MODE\": \"$TLS_MODE\", \"DOMAIN_PRIMARY\": \"$DOMAIN\", \"users\": {\"administrator\": {\"authorized_keys\": [\"$SSH_PUBLIC_KEY\"]}}}" &&
    infinito administration deploy dedicated "$INVENTORY/devices.yml" \
      --password-file "$INVENTORY/.password" \
      --diff -vv'
```

## Persona contract opt-outs

This role declares `PERSONA_ADMINISTRATOR_BLOCKED` and `PERSONA_BIBER_BLOCKED` in `templates/playwright.env.j2` for two different reasons. The MinIO Console version pinned here never renders an SSO button — `/api/v1/login` answers `redirectRules: null` however the identity provider is registered server-side — so there is no in-page OIDC entry point for the shared helper to click. Biber is blocked because the only MinIO policy the role creates is the administrator RBAC group path (`MINIO_OIDC_POLICY_NAME` in `vars/main.yml`, attached in `tasks/02_ldap.yml`) and MinIO has no self-service signup, so biber maps to no policy and has no authenticated surface at either tier.

The administrator journey is covered bespoke in `files/playwright/playwright.spec.js`: the integrated OIDC path is proven at the STS `AssumeRoleWithWebIdentity` tier, and the LDAP variant additionally drives the Console form login and logout. The path back to the generic administrator persona is a Console build that surfaces the configured IdP on its login form.
