I am using Windows to run Selenium Grid 4 (Dynamic Grid) with Docker. Here is the documentation I am following https://github.com/SeleniumHQ/docker-selenium. I have a docker-compose file and a config.toml file, both of which resides in my Documents directory. I have attached it for convenience below.
docker-compose.yml
# 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"

node-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:4.1.2-20220208", "{\"browserName\": \"firefox\"}",
"selenium/standalone-chrome:4.1.2-20220208", "{\"browserName\": \"chrome\"}",

# 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.
url = "http://127.0.0.1:2375"
# Docker image used for video recording
video-image = "selenium/video:ffmpeg-4.3.1-20220208"
# Uncomment the following section if you are running the node on a separate VM
# Fill out the placeholders with appropriate values
#[server]
#host = <ip-from-node-machine>
#port = <port-from-node-machine>
When I perform the following command from powershell or windows command line from within the 'Documents' directory where they both live, get the error:
docker-compose up

Please help me understand what I am missing when following the documentation, which did mention something about mounting assets. I am not sure what that means, but I am using a Windows machine. I just want to run the example as shown here https://www.youtube.com/watch?v=nEyo8cNhZb4&t=391s
