I am new to docker world and I've a requirement for an AWS codebuild project where I need to use selenium/hub image and Dockerfile to run some UI tests. So far what I've done is:
Create docker-compose.yaml file to pull selenium/hub and selenium/node-chrome Create buildspec.yaml file with docker-compose up --build -d and other commands A Dockerfile to build the image FROM python:latest and install some dependencies A small python file to open google.ca using webdriver.Remote
When I build the project in AWS using Code pipeline, I am able to successfully get past initially where it spins up selenium/grid but when I try to run the command "docker run" it errors out as "connection refused"

I am not sure what mistake I am doing here... The error happens in this line from buildspec.yaml
docker run mygridimage:ver1
Thanks for your help.
