Docker-compose部署java項(xiàng)目

前置條件：

安裝docker

安裝docker-compose

防火墻啥的都設(shè)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

# 關(guān)于網(wǎng)絡(luò),如果用到mysql或者redis，并且希望在同一個(gè)網(wǎng)絡(luò)，那么就可以直接使用同一個(gè)網(wǎng)絡(luò)名

# 如果項(xiàng)目有些日志或者寫文件，需要同步到宿主機(jī)器，也需要定義相應(yīng)的卷
