Connect to docker service name from host machine

Let's say I have 2 services defined in my docker-compose.yml like that

# Service app
app:
  networks: 
    - backend
 # Service server
server:
  networks:
    - backend
  ports:
    - 80:80

The app service will upload data on the server service by requesting http://server:80/ and it will display the data url http://server:80/data

Now from my browser I want to click that link but I can't access the server via it's docker hostname, I can only access it via http://localhost:80/data.

Is there anyway to configure my docker-compose to map the hostname server outside of docker so it's accessible from my host machine ?

Solution

  • No.

    You will have to update your hosts file /etc/hosts (C:\Windows\System32\Drivers\etc\hosts on Windows) with an entry similar to below:

    127.0.0.1   localhost server
