실행

mvn clean compile package -DskipTests=true

docker build --tag user-service:1.0 -f Dockerfile .

docker-compose -f docker-compose-user.yml up -d

Api Gateway IP주소 변경

방법 1. 네트워크의 IP 주소 고정(예시)

services:
	zookeeper:
		image: wurstmeister/zookeeper
		ports:
			- "2181:2181"
		networks:
			my-network:
			ipv4_address: 172.18.0.100

방법 2. WebSecurityNew에 Api Gateway 컨테이너 IP주소 직접 추가 ✅

컨테이너 다 지우고

config-server

service-discovery

apigateway-service

이렇게 세 가지를

스프링 빌드
mvn clean compile package -DskipTests=true

이미지 생성 (각각) 하고
docker build --no-cache --tag config-service:lgcns_1 -f .\Dockerfile .

toy-msa로 cd 이후
docker-compose-outer.yml 실행
docker-compose -f docker-compose-outer.yml up -d

outer 서비스들은 자바 코드가 아닌 이미지 바로 받아올 수 있으므로 스프링 빌드, 이미지 생성 과정 없이 바로 docker-compose up 하면 됨

docker-compose -f .\docker-compose-outer.yml up -d
8개 outer 서비스 모두 기동
