IDEA集成docker插件实现SpringBoot项目一键部署

虚拟机centos7.X，docker1.3.X，Win10 Idea2018.1
默认Idea已经下载了Docker插件
默认虚拟机docker已经装了jdk

打开docker配置文件，开放2375端口

[root@xuan ~]# vim /usr/lib/systemd/system/docker.service

在ExecStart=/usr/bin/dockerd-current 后面加上

-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docker

systemctl start docker

查看进程

netstat -tulp

PS：Centos7没有netstat，所以要先下载。

yum install net-tools

防火墙开放2375端口号

[root@xuan ~]# firewall-cmd --zone=public --add-port=2375/tcp --permanent

重启防火墙

[root@xuan ~]# firewall-cmd --reload

Idea连接虚拟机docker

打开小扳手（setting）找到docker，输入虚拟机ip

Springboot项目添加docker-maven-plugin插件.

创建docker文件夹和Dockerfile文件，docker要在src/main里

Dockerfile:

FROM java:8
VOLUME /tmp
ADD docker-1.0-SNAPSHOT.jar app.jar
EXPOSE 8080
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

此处深坑：
ADD 后的jar包名必须和打包后的名字一样，看到配置成功后的镜像名以shaxxx开头，请回头

FROM：选择的jdk
EXPOSE 是端口号和server.port=8082一致
ADD：第一个jar是打包的项目名 第二个是别名

在idea的右边找到Maven Projects，找到Lifecycle，双击package打包
build success 则说明打包成功，此时聚焦docker视图，images会多出一个镜像

创建容器，找到刚刚生成的镜像，点击创建容器

Image ID 是打包生成的那个镜像
Container name 容器名字随便取
Bind ports 8081是docker对外开放的端口，8080是项目端口

设置好后，启动容器，启动成功后去虚拟机查看是否启动成功

docker container ls

访问虚拟机ip+端口号
