Step-by-Step Installation Guide

Installing Docker and Docker Compose:

First things first, we need to install Docker, the engine that runs containerized applications, and Docker Compose,

apt update && 
apt upgrade -y &&
curl -fsSL https://get.docker.com -o get-docker.sh &&
sudo sh get-docker.sh &&
curl -SL https://github.com/docker/compose/releases/download/v2.13.0/docker-compose-linux-x86_64 -o /usr/local/bin/docker-compose &&
chmod +x /usr/local/bin/docker-compose &&
apt-get install docker-compose-plugin

Clone the Repository

Using Git

git clone https://github.com/lukevella/rallly-selfhosted.git
cd rallly-selfhosted

Using Curl (if Git is unavailable)

curl -L https://github.com/lukevella/rallly-selfhosted/archive/master.tar.gz | tar -xz
cd rallly-selfhosted-main

Configure Environment Variables

Generate a Secret Key

Use the following command to generate a secure key:

openssl rand -base64 32

Edit the Configuration File

• Locate the config.env file in the project root.
• Set the following variables:
  • SECRET_PASSWORD: Add the generated secret key.
  • NEXT_PUBLIC_BASE_URL: Specify your server’s base URL (e.g., https://your-domain.com).

Set Up the SMTP Server

• Define your email settings in the config.env file:
  • SUPPORT_EMAIL: The support email address visible to users.
  • SMTP_HOST: SMTP server’s host address.
  • SMTP_PORT: SMTP server’s port (e.g., 25, 465).
  • SMTP_SECURE: Set to “true” if SSL is required.
  • SMTP_USER: SMTP username (if authentication is enabled).
  • SMTP_PWD: SMTP password (if authentication is enabled).

Secure Your Instance

• Restrict User Access:
  Use the ALLOWED_EMAILS variable to define allowed email addresses:
  • Single user:
    ALLOWED_EMAILS="[email protected]"
  • Multiple users:
    ALLOWED_EMAILS="[email protected],[email protected]"
  • Wildcards for domains:
    ALLOWED_EMAILS="*@example.com"

Start the Server

docker compose up -d

This will:

• Set up a PostgreSQL database.
