Using traefik as a reverse proxy in front of selenoid - docker

Question

Im trying to setup a stand-alone server, running selenoid with traefik in front, to get both https and basic-auth capabilities.
I'm able to get everything running, but I get this error every time I try to use the browser:
[SERVICE_STARTUP_FAILED] [wait: http://172.17.0.2:4444 does not respond in 30s]
Here is my docker-compose.yml:

Anyone know what I'm doing wrong?

Answer 1

If anyone stumbles upon the same problem:
networks:
selenoidweb:
name: selenoidweb
driver: bridge
And use this command for your selenoid service:
command: ["-container-network", "selenoidweb", "-conf", "/etc/selenoid/browsers.json", "-video-output-dir", "/opt/selenoid/video", "-log-output-dir", "/opt/selenoid/logs"]
