This guide describes how to set up Briefer on a Google Cloud Platform (GCP) instance using Google’s Compute Engine (GCE), Docker, and, optionally, Nginx as a reverse proxy for public access.

​

1. Prerequisites

• A Google Cloud Platform (GCP) account
• Access to Google Cloud Console
• An SSH key configured to access the GCP instance

​

2. Creating the Compute Engine Instance

1. Access the Google Cloud Console and navigate to Compute Engine > VM instances.
2. Click on “Create Instance.”
3. We recommend configuring the VM with these settings (or higher):
   • vCPUs: 2
   • Memory: 8 GB
   • Disk: 10 GB balanced
   • IOPS: 3060 provisioned
   • Processing capacity: 155 provisioned
     These system requirements are ideal for most cases. However, they can be adjusted up or down depending on your project’s needs and demands.

4. Give your instance a name and click “Create.”

Once the instance is initialized, connect to it via SSH.

​

3. Installing Docker

1. Update the instance’s packages:

   Copy

   sudo apt update && sudo apt upgrade -y
   

2. Install the necessary packages for HTTPS repositories:

   Copy

   sudo apt install apt-transport-https ca-certificates curl software-properties-common
   

3. Add the Docker repository:

   Copy

   curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
   sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu focal stable"
   sudo apt update
   

4. Install Docker:

   Copy

   sudo apt install docker-ce -y
   

5. Add your user to the docker group:

   Copy

   sudo usermod -aG docker ${USER}
   

6. Verify if Docker was installed correctly:

   Copy

   docker ps
   

​

4. Running Briefer

After installing Docker, you can run Briefer using the following command:

docker run -d \
  -p 3000:3000
  -v briefer_psql_data:/var/lib/postgresql/data \
  -v briefer_jupyter_data:/home/jupyteruser \
  -v briefer_briefer_data:/home/briefer \
  briefercloud/briefer

Ensure that Briefer is running by accessing port 3000 on your instance’s public IP:

curl http://<your_public_ip>:3000

The Briefer interface should be accessible directly from the browser using the same URL.

​

(Optional) 5. Configuring Nginx for Public Access

To expose Briefer through a reverse proxy using Nginx:

1. Install Nginx:

   Copy

   sudo apt install nginx -y
   sudo systemctl start nginx
   sudo systemctl enable nginx
   

2. Ensure that Nginx is running by accessing the public IP of the instance in your browser.

3. Configure Nginx to serve Briefer:

   Copy

   cd /etc/nginx/sites-available/
   sudo nano /etc/nginx/sites-available/briefer
   

   We recommend that you configure your Nginx instance with a file similar to the one below.

   Copy

   server {
       listen 80;
   
       server_name _;
   
       client_max_body_size 0;
   
       location / {
           proxy_pass http://localhost:3000;
           proxy_set_header Host $host;
           proxy_set_header X-Real-IP $remote_addr;
           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
           proxy_set_header X-Forwarded-Proto $scheme;
           proxy_request_buffering off;
           proxy_set_header Upgrade $http_upgrade;
           proxy_set_header Connection "Upgrade";
       }
   }
   

4. Enable the new Nginx configs.

   Copy

   sudo ln -s /etc/nginx/sites-available/briefer /etc/nginx/sites-enabled/
   sudo rm /etc/nginx/sites-enabled/default
   sudo nginx -t
   sudo systemctl restart nginx
   

Now, Briefer will be accessible through your instance’s public IP without needing to specify port 3000.
