使用docker-compose build image像并启动应用

1.准备材料

website-1.0.0.jar Dockerfile docker-compose.yml

Dockerfile

FROM java:8-jre-alpine
MAINTAINER test@xx.com
ENV JAVA_OPTS null
WORKDIR /home/portal/website
ADD /home/portal/website/website-1.0.0.jar /home/portal/website/
EXPOSE 8081
ENTRYPOINT [ "sh", "-c", "java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar website-1.0.0.jar" ]
VOLUME /home/portal/website:/home/portal/website

docker-compose.yml(启动单个容器)

version: '3'
services:website:build:context: .dockerfile: Dockerfileimage: website:1.0.0container_name: websiterestart: alwaysnetworks:- netsvolumes: - /home/portal/website/logs/:/home/portal/website/logs/ports:- "8081:8081"environment:    - JAVA_OPTS=-Xmx256M -Dspring.profiles.active=test -Duser.timezone=GMT+08
networks: nets:external: false

2.将以上材料放到/home/portal/website目录

3.build镜像启动应用：执行docker-compose up -d

4.启动多个

docker-compose.yml

version: '3'
services:web1:build: .image: web:1.0container_name: webrestart: alwaysnetworks:- netsvolumes:- /home/portal/web/logs/:/home/portal/web/logs/ports:- "8081:8081"environment:- JAVA_OPTS=-Xmx512M -Dspring.profiles.active=test -DPWD=12345 -Duser.timezone=GMT+08web-backup:image: web:1.0container_name: web-backuprestart: alwaysnetworks:- netsvolumes:- /home/portal/web/logs/:/home/portal/web/logs/ports:- "8082:8081"environment:- JAVA_OPTS=-Xmx512M -Dspring.profiles.active=test -DPWD=12345 -Duser.timezone=GMT+08
networks:nets:external: false
