[🐛 Bug]: Selenium node and hub fail to connect to arbitrary address #2447

Open edison12a opened 3 weeks ago

edison12a commented 3 weeks ago

What happened?

Help: I get a connection error that has a very abnormal address in it. I wonder where the container is getting it from. I can see that much in the logs.

java.net.UnknownHostException: 829c6db0f73a46918aa3a29ec52cd79d-0024402779: 829c6db0f73a46918aa3a29ec52cd79d-0024402779: Name or service not known

This is my local docker compose.

I deployed these containers to AWS with exactly the same properties/config.

version: "3"
services:
  chrome-node:
    image: selenium/node-chrome:4.25.0-20240922
    container_name: chrome-node
    ports:
      - "5555:5555"
      - "7900:7900"
    environment:
      SE_EVENT_BUS_HOST: "selenium-hub"
      SE_EVENT_BUS_PUBLISH_PORT: "4442"
      SE_EVENT_BUS_SUBSCRIBE_PORT: "4443"
      SE_NODE_HOST: "chrome-node"
      SE_NODE_PORT: "5555"
      SE_NODE_MAX_SESSIONS: "5"
      SE_NODE_OVERRIDE_MAX_SESSIONS: "true"
      SE_GRID_URL: "http://selenium-hub:4444"
      SE_ENABLE_TRACING: "false"
    platform: linux/amd64  # Specify platform here

  selenium-hub:
    image: selenium/hub:4.25.0-20240922
    container_name: selenium-hub
    ports:
      - "4442:4442"
      - "4443:4443"
      - "4444:4444"
    environment:
      SE_GRID_MAX_SESSION: "15"
      SE_NODE_PORT: "5555"
      GRID_NEW_SESSION_WAIT_TIMEOUT: "30"
      SE_NODE_SESSION_TIMEOUT: "300"
      SE_GRID_SEASONING_REGISTERING_ATTEMPTS: "5"
      SE_GRID_SEASONING_REGISTERING_RETRY_INTERVAL: "5"
      SE_ENABLE_TRACING: "false"
    platform: linux/amd64  # Specify platform here

Relevant log output

BUT I get this error on the Hub, and the container "shutsdown" later.

Command used to start Selenium Grid with Docker (or Kubernetes), and the container "shutsdown" later.

1. the containers run on AWS ECS. Each has its own Load Balancer & DNS.

2. I am able to ping or call each container from the other for example, I can CURL the hub from the node and vice-versa.

Via env var SE_OPTS can you try to add SE_OPTS=--publish-events tcp://0.0.0.0:4442 --subscribe-events=tcp://0.0.0.0:4443 to Hub config?

edison12a commented 3 weeks ago

@VietND96

I got the error:

chrome-node   | Was passed main parameter '--subscribe-events=tcp://selenium-hub:4443' but no main parameter was defined in your arg class

but adding "SE_OPTS: "--hub http://selenium-hub:4444" did the trick. the chrome node now throws no connection error but still shutsdown after its connection attempts. The selenium hub still has all the errors.

VietND96 commented 2 weeks ago

If having time, can you share some details on the infrastructure that you deploy the container Which service in AWS, and how is the network configured to have an arbitrary address assigned to the container?
