Selenium Grid Configuration

Selenium Grid Configuration​

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

  • Changing the max concurrency setting for 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: <생략>
        name: selenium-hub-tcp-services
        namespace: jenkins
        resourceVersion: '146411402'
        uid: 286d5a55-c34b-40a8-b482-93d4503612ab

    2. Add port configuration to the 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

    3. Add the configmap settings to the Ingress controller Deployment.

      spec:
          containers:
            - args:
                - /nginx-ingress-controller

                - '--tcp-services-configmap=jenkins/selenium-hub-tcp-services'

    4. 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.
