Building your own docker images of SeleniumHQ/docker-selenium

Path is wrong, use build: /etc/docker-selenium/StandaloneChromeDebug/ without .
If you try to cd to ./etc/docker-selenium/StandaloneChromeDebug/, you will get an error.

version: "3.5"services:   selenium-hub:        container_name: selenium-hub        build: /etc/docker-selenium/StandaloneChromeDebug/        volumes:            - /dev/shm:/dev/shm        ports:            - "4444:4444"            - "5900:5900"        environment:           - HUB_HOST=selenium-hub           - HUB_PORT=4444

Exapmle:

You don't really need to go through all of the fuss of building new image unless you need to add something new in the image.

If you want to use the image as it is, use the following docker-compose configuration:

version: "3.5"services:  selenium-hub:    container_name: selenium-hub    image: selenium/standalone-chrome-debug    volumes:      - /dev/shm:/dev/shm    ports:      - "4444:4444"      - "5900:5900"    environment:      - HUB_HOST=selenium-hub      - HUB_PORT=4444

If you still want to use your image that you have built locally, use the following docker-compose configuration:

version: "3.5"services:  selenium-hub:    container_name: selenium-hub    build: /etc/docker-selenium/StandaloneChromeDebug/    volumes:      - /dev/shm:/dev/shm    ports:      - "4444:4444"      - "5900:5900"    environment:      - HUB_HOST=selenium-hub      - HUB_PORT=4444

I feel you are using "build" tag in your compose file rather than "image". Please use "image" tag instead and see if that runs your image correctly.

Also can you please show how you are launching your docker services and what the output is?
