Prerequisites

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

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

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

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.

   The -d option runs the containers in the background.
