[실습] 포트번호 1개만 사용하여 vhost 환경 구현

[choi3179]

기존 환경

• lb(localhost:8001) 호출 시 serv-a(localhost:8002), serv-b(localhost:8003)이 번갈아가며 호출된다.

  $ sudo docker network inspect pd24-bridge

• https://github.com/choi3179/docker-nginx-vhost/issues/3#issuecomment-1943112551

[choi3179]

수정

• serv-a와 serv-b에는 바로 접근할 수 없지만 lb(localhost:8001) 호출 시 serv-a와 serv-b가 번갈아가며 호출

이미지 생성

• 현재 serv-a, serv-b 컨테이너의 스냅샷 이미지 생성

  $ docker commit serv-a choi3179/vhost-serv-a
  $ docker commit serv-b choi3179/vhost-serv-b

컨테이너 생성

$ docker run --name serv-a -d choi3179/vhost-serv-a
$ docker run --name serv-b -d choi3179/vhost-serv-b

네트워크에 컨테이너 연결

$ docker network connect pd24-bridge serv-a
$ docker network connect pd24-bridge serv-b

결과

$ docker network inspect pd24-bridge
