Beego-使用docker-compose实施中的端口号，而不是使用app.conf中的端口号

Question

I am trying to run the beego application using docker with the help of docker-compose. I am able access the demo application in http://localhost:8081 URL after running docker-compose up.

docker-compose.yml

version: "2"

services:
  app:
    build: .
    volumes:
      - .:/go/src/hello
    ports:
      - "8080:8080"
    working_dir: /go/src/hello
    command: bee run

Dockerfile

FROM golang:1.10

## Install beego and the bee dev tool
RUN go get github.com/astaxie/beego && go get github.com/beego/bee

app.conf from beego framework

appname = hello
httpport = 8081
runmode = dev

How can I overwrite the httpport(8081) in app.conf using ports(8080) number used in app from docker-compose.yml. After running docker-compose up application runs in port 8081 not in 8080. How can I solve this?

Answer 1

You shouldn't need to update the app.conf to 8080 use the ports to have the docker container listen on 8081 and respond to 8080.

Change - "8080:8080" to - "8080:8081"

First port is what the docker container will respond to and the second port is the port of the application within the container.
