It provides a simple alternative to heavier database administration platforms and runs as a compact standalone application with a clean web interface. ## About Hosting Adminer This template deploys **Adminer as a standalone database management interface**. No database server is bundled with the template. After deployment, you can connect Adminer to an existing database running on Railway, another cloud platform, a VPS, or another reachable server using your own database credentials. Adminer is particularly useful when you need quick access to database tables, records, indexes, schemas, and SQL queries without installing a desktop client. The template uses the built-in **Nette** interface design for a cleaner visual experience. ## Included Architecture | Component | Purpose | | ----------------------------- | ------------------------------------------- | | **Adminer** | Browser-based database management interface | | **Railway Public Networking** | HTTPS access to the Adminer interface | | **External Database** | Database supplied by the user | | **Persistent Volume** | ❌ Not required | ```text ┌─────────────────┐ │ User │ └────────┬────────┘ │ ▼ Railway HTTPS Proxy │ ▼ ┌─────────────────┐ │ Adminer │ │ │ │ Browse / Query │ │ Manage Database │ └────────┬────────┘ │ ▼ Existing Database Server ``` ## Common Use Cases * Manage PostgreSQL, MySQL, MariaDB, SQLite, and other supported database systems * Browse tables and records from a browser * Run SQL queries without installing a desktop client * Inspect schemas, indexes, relationships, and database metadata * Perform development and testing database administration * Troubleshoot application data * Connect to databases hosted inside or outside Railway * Use a lightweight temporary database administration interface ## Adminer vs Heavier Database Management Tools | Feature | Adminer | Larger Database Admin Platforms | | ------------------------------- | ----------------------------- | ---------------------------------- | | Lightweight deployment | ✅ Yes | ⚠️ Usually larger | | Single web application | ✅ Yes | ⚠️ Often multi-component | | Browser based | ✅ Yes | ✅ Yes | | SQL query interface | ✅ Yes | ✅ Yes | | Multiple database systems | ✅ Yes | ⚠️ Depends on product | | Persistent application database | ❌ Not required | ⚠️ Often required | | Best Fit | Quick database administration | Advanced enterprise administration | Adminer is a strong fit when simplicity, low resource usage, and fast access are more important than operating a larger database management stack. ## Connecting to a Database After deployment: 1. Open the public Railway URL assigned to Adminer. 2. Select the database system you want to connect to. 3. Enter the database server hostname. 4. Enter the username and password. 5. Enter the database name if required. 6. Sign in. 7. Start browsing tables, querying data, and managing the database. Typical connection information includes: ```text Database System Server / Host Username Password Database Name ``` For databases running inside the same Railway project, use **Railway private networking** whenever possible. For databases outside Railway, use the externally reachable database hostname and port. ## Supported Database Connections The official Adminer image includes support for commonly used database systems such as: * PostgreSQL * MySQL * MariaDB * SQLite * Elasticsearch * SimpleDB Additional database engines may require a customized Adminer image with the appropriate PHP extensions. ## Health Check Adminer runs as a standard HTTP application, so the root endpoint can be used for a simple Railway health check: ```text / ``` The application listens on: ```text 8080 ``` No custom start command is required. ## Persistent Storage Adminer itself does **not require persistent storage**. Database records, schemas, and other persistent data remain stored in the database server that Adminer connects to. This keeps the Adminer deployment lightweight and stateless. ## Security Considerations Adminer is a database administration interface and should be treated as a privileged tool. For production or sensitive environments: * Use strong database credentials. * Prefer private networking for databases running inside Railway. * Avoid exposing database ports publicly unless required. * Do not share database connection credentials. * Restrict access to the Adminer public URL when managing sensitive databases. * Use least-privilege database accounts when full administrative access is unnecessary. Adminer can modify or delete database data depending on the credentials used, so access should be controlled appropriately. ## Dependencies for Adminer Hosting * **Adminer** — lightweight database management application * **Existing Database Server** — supplied separately by the user * **Valid Database Credentials** — required at login * **Railway Public Networking** — HTTPS access to the Adminer interface * **Railway Private Networking** — recommended for databases hosted inside Railway No Redis, PostgreSQL, MySQL, or other database service is automatically created by this template. ### Deployment Dependencies * Adminer Official Website: https://www.adminer.org/ * Adminer Docker Image: https://hub.docker.com/_/adminer * Railway Networking: https://docs.railway.com/networking ## Why Deploy Adminer on Railway? Railway is a singular platform to deploy your infrastructure stack. Railway will host your infrastructure so you don't have to deal with configuration, while allowing you to vertically and horizontally scale it. By deploying Adminer on Railway, you get a lightweight browser-based database management interface that can connect to databases inside or outside your Railway project without requiring additional infrastructure. ## Similar templates - [Rocky Linux](https://railway.com/deploy/rocky-linux) — Hosted Rocky Linux 9 workspace with SSH and persistent storage. 🚀 - [Foundry Virtual Tabletop](https://railway.com/deploy/X5tR6G) — A Self-Hosted & Modern Roleplaying Platform - [Letta Code Remote](https://railway.com/deploy/letta-code-remote) — Run a Letta Code agent 24/7.
