General

Hi,

I am trying to access service from Ajax requests like this http://gateway:4000/auth
And my docker-compose file looks as below

version: '2’
services:
UI:
image: arbitrage/ui
restart: always
ports:
- 8182:8182

registry:
image: arbitrage/registry
restart: always
ports:
- 8761:8761
logging:
options:
max-size: "10m"
max-file: “10”

gateway:
image: arbitrage/gateway
restart: always
links:
- registry
ports:
- 4000:4000
logging:
options:
max-size: "10m"
max-file: “10”

I am getting the error

OPTIONS http://gateway:4000/auth net::ERR_NAME_NOT_RESOLVED

What am I missing. Can some one please help

gateway is a name that just resolves within your docker network.
You bind your gateway:4000 to your localhost:4000.

So access it with http://localhost:4000/ should work for you

Hi,
Thanks for response. It is not accessible with http://localhost:4000. I had tried this earlier only.
But if I hard code container ip then it becomes accessible. But I don’t want to hard code IP address.

hard to guess where the problem lies without detailed information about your environment.
I guess you do not have a native docker installation, but are using boot2docker.
