Selenoid UI is not getting launched on 8081 port when I am creating infrastructure through docker-compose.yml file

Question

docker-compose.yml file

        },

        }

    },
  "chrome": {

    "versions": {
            "89.0": {

                "port": "4444",
                "path": "/"
            }
        },
        "versions": {

                "image": "selenoid/vnc:chrome_91.0",
                "port": "4444",
                "path": "/"
            }
        }

  }
}

Executing below commands in sequence:

• docker network create selenoid command
• docker-compose up -d command
• docker ps -a

All the containers are running up.

When I tried to launch localhost:8081 for selenoid UI, it's not working as expected.

I want to run my selenoid UI on 8081 only as 8080 port is occupied by my local Jenkins.

Please let me know if I am missing any configuration and how can I access selenoid UI on 8081 port.

Thanks.

Answer 1

You can change the selenoid UI port in the docker-compose service to map to port 8080 like:

  selenoid-ui:
      image: "aerokube/selenoid-ui:latest"
      container_name: selenoid-ui
      links:
          - selenoid
      ports:
          - "8081:8080"

Or you just change the port that it is listening like in this answer passing the parameter:

-listen :8081
