How to Install Ralph on Fedora CoreOS Latest

Ralph is an open-source asset management system that allows you to keep track of your physical assets such as servers, computers, and other equipment. It provides an easy-to-use web interface for managing your assets, generating reports, and monitoring their performance. Fedora CoreOS is a minimal and secure operating system that runs containerized applications. In this tutorial, we will show you how to install Ralph on Fedora CoreOS latest version.

Prerequisites

A machine running Fedora CoreOS latest version
A user account with root privileges
Docker and docker-compose installed on the system

Step 1: Install Docker and Docker Compose

To install Docker and Docker Compose on your Fedora CoreOS system, follow the steps below:

Update your system's package index by running the command:
```
sudo dnf update
```
Install Docker by running the command:
```
sudo dnf install docker
```
Start the Docker service and enable it to start on boot with the command:
```
sudo systemctl start docker
sudo systemctl enable docker
```
Install Docker Compose by running the command:
```
sudo dnf install docker-compose
```
You may need to install the pip package manager first.
```
sudo dnf install python3-pip
```

Step 2: Clone Ralph Git Repository

Create a new directory where we’ll store the application files:
```
mkdir ralph
cd ralph
```
Clone Ralph’s Git repository by running the command below:
```
git clone https://github.com/allegro/ralph.git
```

Step 3: Install Ralph

To install Ralph, run the following Docker Compose command:

sudo docker-compose -f docker-compose-fedoraco.re.yaml up -d

This command will download and build Ralph’s Docker images, and then start the services in the background.

Creating network "ralph_default" with the default driver
Creating ralph-nginx-1 ... done
Creating ralph-db-1    ... done
Creating ralph-vars-1  ... done
Creating ralph-web-1   ... done
Creating ralph-worker-1 ... done

To verify that Ralph is running, run the following command:

sudo docker ps

This will list all Docker containers running on the system, including Ralph's services.
