Object Storage (MinIO)

MyPanel runs an S3-compatible object store on your server by wrapping MinIO in a standard container — the same way the Mail Server wraps docker-mailserver. Use it to store images, uploads and media and serve them over URLs.

Free trial

Free can install the engine and create 1 bucket to try it out. The Pro plan unlocks unlimited buckets.

Requirements

• A Linux VPS with Docker (the panel pulls the MinIO + mc images when you click Install).

Install & run

Open the Storage menu. The status card shows where the engine is:

1. Not installed — click Install MinIO (the panel pulls the image and starts the container; may take a few minutes).
2. Stopped — click Start.
3. Running — the bucket management section appears right below.

Uninstall removes the container; confirm again if you also want to wipe the data.

Buckets & access keys

While the engine is running:

• Create a bucket — give it a name (lowercase, digits, -, .), optionally attach a website and enable Public read (so images load over a URL).
• Each bucket gets an access key (access key + secret) scoped to that bucket only — one bucket’s key cannot touch another bucket.
• The secret is shown only once at creation. Save it immediately; afterwards your only option is Rotate key to issue a new one.
• Public / Private — toggle anonymous read at any time.
• Delete bucket — if it still contains objects, the panel offers to empty then delete (or delete only if empty).

Caution

The secret cannot be retrieved later. If you lose it, use Rotate key — the old key stops working immediately, so update wherever it’s used.

External access (one-click + SSL)

For safety, MinIO only listens locally (127.0.0.1): the API/images on port 9000, the Console (admin UI) on 9001. Right on the Storage page, use the “Expose on domain” button — the panel creates a Reverse Proxy website to MinIO and issues Let’s Encrypt automatically once DNS resolves. Two separate entries:

Purpose	Button in the panel	Points to
Serve images / use the S3 API	Expose on domain	127.0.0.1:9000
Open the admin Console	Expose Console on domain	127.0.0.1:9001

After exposing, point the domain’s A record to the server IP (SSL is issued automatically). Each domain counts as one website toward your plan limit. MyPanel’s Reverse Proxy supports WebSocket, so the Console works fully.

Config for external systems

Connect with Endpoint https://<domain>, Region us-east-1, and path-style enabled (forcePathStyle: true) — the client uses path-style. The Storage page shows these values ready to copy.

Use with WordPress / apps

Buckets are standard S3, so any S3-capable plugin/SDK works:

• Endpoint — https://<domain> exposed above (or http://127.0.0.1:9000 if running on the same machine).
• Access key / Secret key — the bucket’s key (needed to upload).
• Bucket — the bucket name. Be sure to enable path-style in the SDK config.

For WordPress: an offload-media plugin (such as WP Offload Media) takes these values to push your media library to MinIO.

Public image link (bucket with public-read on): https://<domain>/<bucket>/<file> — use it directly as an <img src>.

Backing up data

MinIO’s actual data lives at /var/lib/mypanel/minio/data on the server.

Caution

Don’t rely on the panel’s config backup for object data — images/files can be many GB, unsuitable for bundling. Back it up separately:

• Mirror to another store — mc mirror (or MinIO replication) pushes buckets to another S3/MinIO on a schedule.
• rsync / snapshot — back up the /var/lib/mypanel/minio/data folder at the system level on a schedule.
