Request from Frontend Container to Backend container
I have seen several possibilities how to communicate between docker containers. I tried the most of them except proxying which i cant translate to my scenario.
I have a vue-frontend, java-backend- container.
In the frontend i use axios to make http request.
I want to make a http request axios.get(http:localhost:7080/ping), which gives me status 200 but I dont get an response and some CORS problem.(Which is very strange, because the cors header are present if i use postman for the request)
If i use axios.get(http:container_name:7080/ping) I get some other errornet::ERR_NAME_NOT_RESOLVED.
Other solutions (using nginx) using reverse proxy. Do I need something like this or do I have some other misconfiguration?
My docker-compose looks like this:
services:
backend:
container_name: backend
build: ./backend
volumes:
- xxx
ports:
- 7048:7048
- 7080:7080
- 7009:9009
frontend:
container_name: frontend
build:
context: ../frontend
dockerfile: ./Dockerfile
volumes:
- ../xxx
ports:
- 8080:8080
#- 8001:8001
depends_on:
- backend
environment:
- NODE_ENV=development
# - CHOKIDAR_USEPOLLING=true

Where is the actual HTTP call happening? Is thefrontendcontainer directly calling the backend, or is it serving up a Web application that's making the outbound HTTP call from the user's browser?

The frontend containers serves a vue.js application which makes the call to the backend

...so the URL needs to be a name the browser can resolve, which is probably the host name of the server running thebackendcontainer (could belocalhostonly in a development environment where you know the browser and the Docker setup are running on the same physical host).
