Selenium Grid Setup

Selenium Grid Setup​

  • Selenium Grid helm chart
    https://github.com/SeleniumHQ/docker-selenium/blob/trunk/charts/selenium-grid/README.md

  • Changing the max concurrency setting of Node Deployment

    spec:
       containers:
          - env:
            - name: SE_NODE_MAX_SESSIONS
              value: "3"
            - name: SE_NODE_OVERRIDE_MAX_SESSIONS
              value: "true"

  • Add External Node

  • Need to expose tcp 4444, 4442, 4443 in ingress.

    1. Add the corresponding content to the configmap.
    apiVersion: v1
    data:
      '4442': jenkins/selenium-hub:4442
      '4443': jenkins/selenium-hub:4443
    kind: ConfigMap
    metadata:
      creationTimestamp: '2023-09-01T07:29:19Z'
      managedFields: <omitted>
      name: selenium-hub-tcp-services
      namespace: jenkins
      resourceVersion: '146411402'
      uid: 286d5a55-c34b-40a8-b482-93d4503612ab
    1. Add port configuration to Ingress controller Service
    - name: proxied-tcp-4442
          nodePort: 30161
          port: 4442
          protocol: TCP
          targetPort: 4442
        - name: proxied-tcp-4443
          nodePort: 32092
          port: 4443
          protocol: TCP
          targetPort: 4443
    1. Add the configmap settings to the Ingress controller Deployment.
    spec:
        containers:
          - args:
              - /nginx-ingress-controller

              - '--tcp-services-configmap=jenkins/selenium-hub-tcp-services'
    1. If the devtools service is not available, check whether the SE_NODE_GRID_URL in selenium-node-config is a URL that can be accessed normally.
