Docker-compose部署java项目

前置条件：

安装docker

安装docker-compose

防火墙啥的都设置好

dockerfile-demo

FROM java:8

VOLUME /tmp

WORKDIR /

ADD ./project-demo-1.0.0.jar project-demo.jar

RUN bash -c 'touch /project-demo.jar'

EXPOSE 8080

ENTRYPOINT ["java","-jar","/project-demo.jar"]

compose-project-demo.yaml

version: '3'

# 关于网络,如果用到mysql或者redis，并且希望在同一个网络，那么就可以直接使用同一个网络名

# docker network create project-demo_bridge

networks:

project-demo_bridge:

driver: bridge

services:

project-demo:

container_name: project-demo

image: project-demo:1.0

restart: always

volumes:

# 同步时间

- /etc/localtime:/etc/localtime:ro

# 如果项目有些日志或者写文件，需要同步到宿主机器，也需要定义相应的卷

- ./data:/etc/project-demo/data

- ./log:/etc/project-demo/log
