Container Isolations- Websocket reverse proxy - Remote Browser Isolations

Demo video

NOTE: use password as password to access the container

# pre-requisite - install minikube
# curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
# sudo install minikube-linux-amd64 /usr/local/bin/minikube

# minikube start

./run_k8s_minikube.sh

- Will create a docker network `rbix-network`

./run.sh

• responsible for managing the containers and provisioning new rbix-rbi containers.

• expose few endpoints

  • /try endpoint to spin up a new container
  • /status/{container_id} endpoint to check status of a container (running or not)
  • /stop/{termination_token} endpoint to stop a container

• Client, calls POST http://api.rbixlabs.com/v1/try -> rbix-api-server now spins up a new container and returns the session_id and termination_token, also schedules background job to terminate the container after 10 mins.

• it's a simple reverseproxy server, which will proxy the websocket connection to the specific container.
• when client connects to reverseproxy ws://in.malwaresamathi.rbixlabs.com/dfv-4c1c34a5-4f1c-47ae-a812-e414f0fc41c9/ws, it makes a downstream connection with the rbix-rbi container and upgrade the client connection to websocket.
• upon successful connection, it will start streaming the message from the container to the client.

• simple websocket server, which will stream the message from the container to the client.
• just expose the container information to the client.
• doesn't implemented the remote browser isolation yet.

• Pixel pushing/streaming
• Page scrubbing

• max 65536 socket connections per server
• each socket connection last for min 3 min to max 10 mins
  • in 1 hour, 6*65536 = 3,93,216 connections
  • in 24 hours, (6*24)*65536 = 94,60,224 connections

# create network for rbix
docker network create rbix-network

• /v1/try endpoint to spin up a new container
• /v1/status endpoint to check status of a container (running or not)
• /v1/stop endpoint to stop a container
