How To Set Hostname In Docker Compose | Docker Compose Tutorial
The correct way of assigning a hostname in docker-compose is to define it under the service like this
services:
some-service:
networks:
some-network:
aliases:
- alias1
- alias2
But some users are experiencing issues with this method. If this is not working for you with docker run then assign the container a name like below:
docker-compose run --name alias1 some-service
Another simplest way is to just set the container name in the docker-compose.yml
services:
dns:
image: phensley/docker-dns
container_name: affy
