vim /lib/systemd/system/docker.service
#修改ExecStart这行
ExecStart=/usr/bin/dockerd  -H tcp://0.0.0.0:2375  -H unix:///var/run/docker.sock
# 重新加载配置文件
systemctl daemon-reload 
#重启服务
systemctl restart docker.service 
#查看端口是否开启
 netstat -nlpt
#直接curl看是否生效
curl http://127.0.0.1:2375/info

Idea中Docker配置

可以直接在idea->plug 或者在官网下载idea对应版本的的Docker integration 安装。安装后restart Idea 即可。

FROM java:8
VOLUME /tmp
COPY target/demo-0.0.1-SNAPSHOT.jar demo.jar
RUN bash -c "touch /demo.jar"

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

4、创建Docker镜像

在idea右上角maven插件中执行package进行打包
