Getting SessionNotCreatedError when trying to run scripts from Jenkins pipeline

Question

I am trying to run my protractor scripts on jenkins pipeline and getting the SessionNotCreatedError when it tries to access the Selenium address. When I run the same on local its working fine. Not sure what's going on.

Conf.js script

let domainName = util.domainName;
exports.config = {
  seleniumAddress: 'http://selenium-hub:4444/wd/hub', //for testing in the pipeline
  directConnect: false, // Set to true for local testing, or provide a link to a running selenium grid.
  // specs: ['e2e/**/mailbox-test.js', 'e2e/**/email-dumps-test.js'],
  specs: ['e2e/**/*-test.js'],
  capabilities: {
    browserName: 'chrome',
    acceptInsecureCerts: true,
    'goog:chromeOptions': {
      w3c: false,
      args: [
        '--no-sandbox',
        '--headless',
        '--disable-gpu',
        '--window-size=1200,1200',
        '--disable-dev-shm-usage',
        '--allow-insecure-localhost',
        '--allow-running-insecure-content',
        '--ignore_ssl',
        '--user-agent=Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.130 Safari/537.36',
      ],
    },
  },

  allScriptsTimeout: 600000,
  baseUrl: eaUrl,
  framework: 'jasmine',

  jasmineNodeOpts: {
    isVerbose: true,
    showColors: true,
    includeStackTrace: true,
    defaultTimeoutInterval: 600000,
    stackTrace: false
  },

Answer 1

I am adding my observations as others might need if they get similar issues and this might help them too. After a long long investigation of the console output in Jenkins with my docker installation scripts, I noticed that we are trying to install the latest version of the selenium hub and chrome node but the docker command doesn't include the SE_EVENT_BUS_HOST information. After changing my code from

docker run -d --name selenium-node-chrome -e HUB_HOST=selenium-hub --shm-size="2g" nexus2.xxx.com:18443/selenium/node-chrome

to

docker run -d --name selenium-node-chrome -e SE_EVENT_BUS_HOST=selenium-hub --shm-size="2g" -e SE_EVENT_BUS_PUBLISH_PORT=4442 -e SE_EVENT_BUS_SUBSCRIBE_PORT=4443 nexus2.xxx.com:18443/selenium/node-chrome

Then it started working for me.
