MinIO

Why deploy MinIO on Render?

MinIO is an open-source, S3-compatible object storage server. It allows developers to self-host object storage with an API compatible with Amazon S3, enabling local development, private cloud storage, or migration away from AWS without changing application code.

This template gives you a production-ready MinIO setup with two pre-wired services: an S3-compatible API server with auto-generated admin credentials and a separate web console for management, all with managed TLS handled automatically. Instead of manually configuring MinIO's dual-service architecture, generating secure credentials, and setting up certificates, you get a working object storage system with one click. Render's SSD-backed storage with automatic backups means your data is protected without configuring backup jobs yourself.

Architecture

What you can build

After deploying, you'll have a running MinIO server that provides an S3-compatible object storage API, along with a web console for managing buckets and files. You can immediately start storing and retrieving objects using any S3-compatible SDK or MinIO's CLI, with TLS handled automatically. Admin credentials are auto-generated and accessible from your Render dashboard.

Key features

• S3-compatible API: Deploys a MinIO server providing S3-compatible object storage API endpoints.
• Managed TLS certificates: Automatically provisions and manages TLS certificates for secure HTTPS connections.
• SSD storage with backups: Uses SSD-backed persistent storage with automatic backup functionality.
• Separate web console: Includes an optional dedicated web console service for browser-based bucket and object management.
• One-click deployment: Uses render.yaml Blueprint spec for instant deployment with auto-generated admin credentials.

Use cases

• Startup developer deploys S3-compatible storage without AWS vendor lock-in
• Solo founder stores user uploads with automatic backups and managed TLS
• Backend engineer replaces expensive cloud storage with self-hosted MinIO instance
• Side project creator adds file storage to Render app in one click

What's included

Next steps

1. Open the MinIO web console URL and log in with the admin credentials from the Environment tab in your Render dashboard — You should see the MinIO Console dashboard with options to create buckets and manage objects
2. Create a new bucket in the console by clicking 'Create Bucket' and giving it a name — The bucket should appear in your buckets list and show as empty with 0 objects
3. Test the S3 API by uploading a file to your new bucket using the console's Object Browser — The file should appear in the bucket with its name, size, and upload timestamp visible
