Deploy and Host AlmaLinux 9 - Web Terminal on Railway

AlmaLinux 9 - Web Terminal is a browser-accessible AlmaLinux 9 workspace hosted on Railway. Instead of connecting through SSH, users open a web terminal, log in with only a USERNAME and PASSWORD, and get an enterprise Linux compatible command-line environment for testing, development, diagnostics, package installation, and lightweight Linux workflows.

About Hosting AlmaLinux 9 - Web Terminal

Hosting AlmaLinux 9 - Web Terminal on Railway involves deploying a containerized AlmaLinux 9 environment with a browser-based terminal interface powered by ttyd. Railway handles the deployment, runtime, networking, environment variables, and infrastructure, while the template exposes a secure web terminal protected by user-defined login credentials. Users only need to set USERNAME and PASSWORD during deployment, then open the generated Railway service URL to access the terminal from a browser. This makes it useful for quick Linux access, RPM-based package testing, command-line learning, diagnostics, and lightweight cloud-hosted development workflows without manually managing a VPS or configuring local SSH access.

Common Use Cases

• Browser-based AlmaLinux 9 terminal for diagnostics, testing, and debugging
• RPM-based enterprise Linux sandbox for package installation and command testing
• Lightweight cloud workspace for scripts, automation, logs, and temporary Linux tasks
• Learning and practicing AlmaLinux, dnf, shell commands, and system inspection
• Running quick development or DevOps experiments from any device with a browser
• Creating a web-accessible Linux environment without requiring local SSH setup
• Testing workloads in an AlmaLinux 9 / RHEL 9 compatible environment

Dependencies for AlmaLinux 9 - Web Terminal Hosting

• Railway account for deploying and managing the web terminal service
• USERNAME environment variable for web terminal login
• PASSWORD environment variable for web terminal login
• TTYD_VERSION=1.7.7 for the browser-based terminal server
• TZ=Asia/Jakarta as the default timezone, adjustable before deploy or later from Railway Variables
• Railway service domain or custom domain to access the terminal from a browser
• Optional Railway Volume mounted to /root/workspace for persistent files across restarts and redeployments

Deployment Dependencies

This template uses the following components and resources:

• Official AlmaLinux Docker image: almalinux:9
• AlmaLinux official website: https://almalinux.org/
• AlmaLinux documentation: https://wiki.almalinux.org/
• AlmaLinux release notes: https://wiki.almalinux.org/release-notes/
• ttyd project: https://github.com/tsl0922/ttyd
• Railway documentation: https://docs.railway.com/
• Railway environment variables: https://docs.railway.com/guides/variables
• Railway Volumes: https://docs.railway.com/reference/volumes

Implementation Details

This template is designed so users only need to provide two required environment variables for login:

USERNAME=your_username
PASSWORD=your_secure_password

By default, the template also uses Jakarta timezone:

TZ=Asia/Jakarta

You can change the timezone before clicking Deploy, or update it after deployment from the Railway service Variables section.

The template also uses the following terminal server version:

TTYD_VERSION=1.7.7

ttyd provides the browser-based terminal interface for the AlmaLinux container.

After deployment, open the Railway-generated public URL in your browser and log in using the configured username and password.

Inside the web terminal, verify the AlmaLinux version:

cat /etc/os-release

You should see AlmaLinux 9 information. AlmaLinux 9 is an enterprise Linux compatible distribution designed for workloads that need a stable RPM-based environment with dnf package management.

Install common tools with dnf as needed:

dnf update -y
dnf install -y curl wget nano vim git htop procps-ng iproute ca-certificates

The Railway Volume should be mounted to:

/root/workspace

Store persistent files inside this path so they survive service restarts and redeployments.

Example persistent workspace:

cd /root/workspace
mkdir -p projects logs scripts

Avoid storing important files outside /root/workspace, because files outside the mounted Railway Volume may be lost after rebuilds or redeployments.

AlmaLinux 9 Notes

AlmaLinux 9 provides a stable, community-driven enterprise Linux environment compatible with the RHEL 9 ecosystem. It is suitable for development, testing, automation, package validation, and command-line workflows that need an RPM-based Linux system. In this template, AlmaLinux 9 runs as a containerized web terminal on Railway, making it accessible directly from the browser with simple username and password authentication.
