3.3 엄브렐라(umbrella) 프로젝트로 서비스 연결 (P267)
엄브렐라 프로젝트는 지정된 표준을 포함하는 기본 저장소 및 표준을 준수하는 다수의 "하위 프로젝트"로 구성된 프로젝트입니다.
엄브렐라 저장소 아래에 개별 마이크로서비스 저장소를 체크아웃하기 위해 오픈 소스 프로젝트 Faux 깃 서브모듈을 사용
마이크로서비스가 포함된 워크스페이스 저장소의 하위 폴더를 업데이트, 커밋, 푸시할 수 있는 완전한 기능의 저장소로 취급
깃 템플릿 복제
https://github.com/inadarei/microservices-workspace
로컬 개발 환경으로 복제
c:\msur> git clone https://github.com/myanjini/microservices-workspace.git
워크스페이스 구성요소 설정
ms-flights와 ms-reservations 마이크로서비스의 저장소를 워크스페이스의 구성요소로 표시
C:\msur\microservices-workspace\fgs.json
{
"ms-flights": {
"url": "https://github.com/naanjini/ms-flights.git"
},
"ms-reservations": {
"url": "https://github.com/naanjini/ms-reservations.git"
}
}
ms-flights와 ms-reservations 마이크로서비스를 워크스페이스로 가져옮
C:\msur\microservices-workspace> make update
git clone -b master https://github.com/myanjini/ms-flights.git ms-flights
Cloning into 'ms-flights'...
fatal: Remote branch master not found in upstream origin ⇐ git checkout -b "master" 후 git push origin master
git clone -b master https://github.com/myanjini/ms-reservations.git ms-reservations
Cloning into 'ms-reservations'...
C:\msur\microservices-workspace> make update
git clone -b master https://github.com/myanjini/ms-flights.git ms-flights
Cloning into 'ms-flights'...
git pull

프로젝트 이름 변경
ms-flights, ms-reservations, microservices-workspace 모두 동일한 프로젝트 이름을 가지고 있어야 함

라우팅 설정
Traefix 엣지 라우터를 사용해 마이크로서비스로의 라우팅을 제공 → 이를 위해 각 마이크로서비스의 docker-compose.yaml 파일에 Traefix 관련 레이블을 추가해 적절한 서비스로 트래픽이 라우팅되도록 구성
C:\msur\microservices-workspace\ms-flights\docker-compose.yml
version: '3.4'
services:
ms-flights:
container_name: ms-flights
labels:
- 'traefik.enable=true'
- 'traefik.http.routers.ms-flights.rule=PathPrefix(`/flights`)'
user: root # avoids ton of volume mounting headaches in dev mode.
