springCloud Finchley 微服务架构从入门到精通【十】Docker Maven插件部署项目

##一、Centos7 上安装docker##

docker服务器的安装部署

1、Docker 要求 CentOS 系统的内核版本高于 3.10 ，验证CentOS 版本是否支持 Docker 。

root@bogon ~]# uname -r

2、更新yum包到最新

root@bogon ~]# sudo yum update

3、卸载旧版本

[root@bogon ~]# sudo yum remove docker  docker-common docker-selinux docker-engine

4、设置yum源

[root@bogon ~]# sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

5、安装docker

[root@bogon ~]# sudo yum install docker-ce

6、启动并加入开机启动

[root@bogon ~]# sudo systemctl start docker
[root@bogon ~]# sudo systemctl enable docker

7、验证是否安装成功

[root@bogon ~]# docker version

这里写图片描述

##二、centos7安装 jdk 1.8 和 maven 3.5##

由于安装过于简单，自行百度

##二、修改springcloud项目配置##

###1、pom.xml 中添加 docker-maven-plugin 插件，完整pom.xml如下###

###2、构建镜像文件###

进入项目目录，运行 mvn clean package docker:build -DskipTests

注： -DskipTests 为跳过测试，springboot测试类会再启动一个主类，有时会报单例错误

[root@localhost Downloads]# cd commonservice-eureka
[root@localhost commonservice-eureka]# mvn clean package docker:build -DskipTests

//以下为输出日志：
Digest: sha256:c1ff613e8ba25833d2e1940da0940c3824f03f802c449f3d1815a66b7f8c0e9d

使用docker images查看镜像

[root@localhost commonservice-eureka]# docker images
REPOSITORY             TAG                 IMAGE ID            CREATED             SIZE

java                   latest              d23bdf5b1b1b        16 months ago       643MB
[root@localhost commonservice-eureka]#

启动镜像

[root@localhost commonservice-eureka]# docker run -p 8761:8761 commonservice-eureka
