[Docker] Nginx 를 사용한 SubDomain(서브도메인) 분기

[Nginx-proxy 이미지 사용]

- docker-compose 를 통한 컨테이너 구축

- 서브도메인을 분기 시켜줄 프록시 컨테이너

* nginx-proxy.yaml

version: '2'

services:

nginx-proxy:

container_name: nginx-proxy

image: jwilder/nginx-proxy

ports:

- "80:80"

volumes:

- /var/run/docker.sock:/tmp/docker.sock:ro

- /home/test/nginx-proxy/log:/var/log/nginx

networks:

default:

external:

name: nginx-proxy

- 기본 웹서버 컨테이너

* nginx-www.yaml

version: '2'

services:

nginx-www:

image: nginx:latest

environment:

- VIRTUAL_HOST=www.domain.com

container_name: nginx-www

networks:

default:

external:

name: nginx-proxy

- 서브도메인을 테스트 할 test 컨테이너 (test 대신 다른 웹서버 이미지를 사용해서 테스트 해야합니다.)

* test.yaml

version: '2'

services:

test-container:

image: test

container_name: test

environment:

- VIRTUAL_HOST=sub.domain.com

- VIRTUAL_PORT=3000

networks:

default:

external:

name: nginx-proxy

- 프록시 컨테이너 내 nginx 설정 파일 확인

/etc/nginx/conf.d/default.conf
