docker-compose
Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a YAML file to configure your application’s services. Then, with a single command, you create and start all the services from your configuration. To learn more about all the features of Compose, see the list of features.
참고페이지: https://docs.docker.com/compose/ , https://docs.docker.com/compose/overview/
docker-compose 란? 간단히 설명하면 YAML 방식 설정파일을 이용하여 여러 컨테이너를 설치? 하고 운영 하는툴로 보시면 됩니다.

docker-compose 설치
test@ubuntu1604:~$ sudo curl -L https://github.com/docker/compose/releases/download/1.19.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose test@ubuntu1604:~$ sudo chmod +x /usr/local/bin/docker-compose test@tomomo:~$ docker-compose --version docker-compose version 1.11.2, build dfed245 test@tomomo:~$
docker-compose 를 이용하여 web-service 를 테스트 합니다.
(Nginx + php71 + mysql57)

version : compose file format 참고페이지 https://docs.docker.com/compose/compose-file/#reference-and-guidelines
services: 컨테이너 별로 만들어 주면 됩니다. ex) nginx , apache , mariadb , mysql 등
mysql 필드 설명
image: mysql:5.7 version 을 사용합니다.
ports: 3306:3306 / host의 3306 포트와 컨테이너의 3306 포트를 연결 합니다.
volumes: /mysql:/var/lib/mysql 내부 디렉토리 와 컨테이너 디렉토리를 연결 합니다.
restart: always 리부팅시에도 자동으로 실행을 합니다.
environment: 환경변수 설정?
MYSQL_ROOT_PASSWORD: root / mysql root 패스워드
MYSQL_USER: docker / mysql user 생성
MYSQL_PASSWORD: docker / user password 생성
MYSQL_DATABASE: docker / user database 생성
nginx 필드 설명
links: – php / php 컨테이너와 연결을 합니다.
depends_on: 서비스와 시작순서간의 종속성 설정?
The depends_on option can be used in place of links to indicate dependencies between services and startup order
참고페이지: https://docs.docker.com/compose/compose-file/compose-versioning/#version-2
php 필드 설명
build: php / Dockerfile 을 통하여 build 시 build 라는 필드를 입력합니다.
expose: 9000 : 외부로 연결하지 않고 다른 컨테이너에서만 액세스 할수 있습니다.
Expose ports without publishing them to the host machine – they’ll only be accessible to linked services. Only the internal port can be specified.
참고페이지: https://docs.docker.com/compose/compose-file/compose-file-v2/
links: mysql 컨테이너와 연결
Link to containers in another service. Either specify both the service name and a link alias (“SERVICE:ALIAS”), or just the service name.
