How to Install GRR on Fedora CoreOS Latest

GRR is an open-source security platform that provides remote incident response and live forensics capabilities. In this tutorial, we will guide you on how to install GRR on the latest version of Fedora CoreOS.

Prerequisites

To install GRR on Fedora CoreOS Latest, you must have:

• A running instance of Fedora CoreOS Latest
• Root or sudo privileges
• Internet connectivity

Step 1: Set Up a Non-Root User

It is recommended to create a non-root user to perform the installation.

1. Connect to your Fedora CoreOS Latest instance via SSH.

2. Run the following command to create a non-root user:

   sudo useradd -m -s /bin/bash grruser
   

3. Set a password for the new user:

   sudo passwd grruser
   

4. Add the new user to the sudo group:

   sudo usermod -aG sudo grruser
   

5. Switch to the new user account:

   su grruser
   

6. Change directory to the home directory:

   cd ~
   

Step 2: Install Docker

GRR requires Docker, so you need to install it on your Fedora CoreOS Latest instance.

1. Update the package list:

   sudo dnf update
   

2. Install the required packages:

   sudo dnf -y install docker
   

3. Start Docker and enable it to start automatically at boot:

   sudo systemctl start docker
   sudo systemctl enable docker
   

Step 3: Deploy GRR

To deploy GRR:

1. Clone the GRR git repository:

   git clone https://github.com/google/grr-docker-suite.git
   

2. Change to the grr-docker-suite directory:

   cd grr-docker-suite
   

3. Copy the example configuration file:

   cp docker-compose.yml.example docker-compose.yml
   

4. Open the docker-compose.yml file in a text editor:

   nano docker-compose.yml
   

5. Edit the image field so that it points to the latest version of the GRR Docker image:

   image: devome/grr-server:latest
   

6. Save and close the file.

7. Deploy GRR:

   docker-compose up -d
   

   The -d option runs the containers in the background.
