Memcached – How to configure host machine to access Apache ServeName in Docker

How to configure my Dockerfile or docker-compose for that my host machine can resolve a ServerName like http://myapp.env instead http://localhost:8080?!

I tried to configure my local hosts file with the ip from container, but without success, like this

172.20.0.3 goforce.env

My Dockerfile

FROM php:7.2-apache

LABEL maintainer="rIckSanchez"
LABEL project="MyApp"

COPY .docker/php/php.ini /usr/local/etc/php/
COPY .docker/apache/000-default.conf /etc/apache2/sites-available/
COPY . /srv/app

RUN apt-get update && apt-get install --no-install-recommends -y 
    wget 
    nano

    Your docker web server port 80 is mapped to your localhost port 8080. To go around the the fact that localhost can’t see the docker private network. The dns won’t be able to map traffic to certain port, but you can access goforce.env:8080 by adding following line to your /etc/hosts file:

    127.0.0.1 goforce.env

    If you want to use just goforce.env, you should change your docker-compose:

    ports:
  - 8080:80 -> to 80:80

    or you could run apache proxy on your host machine and point port 80 to 8080 (if you must run apache on host and docker server at the same time).

    Try using nginx for reverse proxy of the application . Check this url

    Multiple docker containers accessible by nginx reverse proxy
