it seems service is running but I can not access it in http://localhost:8000

Please help

CodePudding user response：

you could access it in http://localhost:9090. 8000 is the port inside your docker container not accessible from outside. The local port is 9090

CodePudding user response：

You're mapping the port 9090 of the host, in this case your local computer, to the container port of 8000. In other words: You should be able to reach it locally on port 9090
