Has anybody found a way to make Tensorboard password-protected?

Question

I have been trying to make the Tensoboard password-protected, but it isn't easy as it is not a Flask app. An issue has been opened last year, but no news since.

As a workaround, you can set --host parameter to 127.0.0.1 and then protect the local port with a basic authentication using nginx or something.. – Kicksorter

As Tensorboard unfortunately does not have password-protection built-in, I used an nginx server within a docker container that acts as a reverse proxy.

Tensorboard is then protected with HTTP basic auth.

nginx.conf

events { worker_connections 1024; }

http {
  server {
    listen 5000;

    server_name localhost;

    location / {
      proxy_pass http://host.docker.internal:5000;
      auth_basic "Restricted Remote";
      auth_basic_user_file /etc/nginx/.htpasswd;
    }
  }
}

To generate the .htpasswd file use the following command:

htpasswd -c .htpasswd admin

docker-compose.yml

version: '3'
services:
  nginx:
    image: nginx:latest
    container_name: nginx_reverse_proxy
    volumes:
      - ./nginx.conf:/etc/nginx/nginx.conf
      - ./.htpasswd:/etc/nginx/.htpasswd
    ports:
      - 5000:5000

To run use docker-compose up -d

I wrote a blog post where I explain how to create your own sharable Tensorboards with authentication on GCP in a cost-effective way. This post includes the Terraform setup so that the solution can be replicated with ease.
