[🐛 Bug]: Dynamic Grid setup fails when the docker images are missing locally #11342
Description
What happened?
When we attempt at following the documentation of Dynamic Grid the docker node does not come up and crashes.
How can we reproduce the issue?
Ensure that you dont have any of the selenium related docker container images in your machine by running
docker container pruneto prune the images being used by stopped containersdocker rmi $(docker images | grep selenium | awk '{print $3}')clean up all selenium images
Create a docker-compose file named docker-compose-v3-dynamic-grid.yml that looks like below:
# To execute this docker-compose yml file use `docker-compose -f docker-compose-v3-dynamic-grid.yml up` # Add the `-d` flag at the end for detached execution # To stop the execution, hit Ctrl+C, and then `docker-compose -f docker-compose-v3-dynamic-grid.yml down` version: "3" services: node-docker: image: selenium/node-docker:4.6.0-20221104 volumes: - ./config.toml:/opt/bin/config.toml depends_on: - selenium-hub-dynamic environment: - SE_EVENT_BUS_HOST=selenium-hub-dynamic - SE_EVENT_BUS_PUBLISH_PORT=4442 - SE_EVENT_BUS_SUBSCRIBE_PORT=4443 ports: - "5005:5005" selenium-hub-dynamic: image: selenium/hub:4.6.0-20221104 container_name: selenium-hub-dynamic ports: - "4442:4442" - "4443:4443" - "4455:4444"In the same directory create a toml configuration file named config.toml with its contents as below:
[docker] # Configs have a mapping between the Docker image to use and the capabilities that need to be matched to # start a container with the given image. configs = [ "selenium/standalone-firefox:4.6.0-20221104", "{\"browserName\": \"firefox\"}", "selenium/standalone-chrome:4.6.0-20221104", "{\"browserName\": \"chrome\"}", "selenium/standalone-edge:4.6.0-20221104", "{\"browserName\": \"MicrosoftEdge\"}" ] # URL for connecting to the docker daemon # Most simple approach, leave it as http://127.0.0.1:2375, and mount /var/run/docker.sock. # 127.0.0.1 is used because interally the container uses socat when /var/run/docker.sock is mounted # If var/run/docker.sock is not mounted: # Windows: make sure Docker Desktop exposes the daemon via tcp, and use http://host.docker.internal:2375. # macOS: install socat and run the following command, socat -4 TCP-LISTEN:2375,fork UNIX-CONNECT:/var/run/docker.sock, # then use http://host.docker.internal:2375. # Linux: varies from machine to machine, please mount /var/run/docker.sock. If this does not work, please create an issue. # I am on mac url = "http://host.docker.internal:2375" # Docker image used for video recording #video-image = "selenium/video:ffmpeg-4.3.1-20220531" # Uncomment the following section if you are running the node on a separate VM # Fill out the placeholders with appropriate values #[server] #host = "10.136.130.15"#<ip-from-node-machine> #port = "5555"#<port-from-node-machine>Setup socat forwarding (I am on Mac and so I installed socat and run the following command, socat -4 TCP-LISTEN:2375,fork UNIX-CONNECT:/var/run/docker.sock
Now bring up the nodes by running docker-compose -f docker-compose-v3-dynamic-grid.yml up
