摘要：一上安裝服務器的安裝部署要求系統的內核版本高于，驗證版本是否支持。

docker服務器的安裝部署

1、Docker 要求 CentOS 系統的內核版本高于 3.10 ，驗證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、卸載舊版本

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

4、設置yum源

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

5、安裝docker

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

6、啟動并加入開機啟動

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

7、驗證是否安裝成功

[root@bogon ~]# docker version

由于安裝過于簡單，自行百度

進入項目目錄，運行 mvn clean package docker:build -DskipTests

注： -DskipTests 為跳過測試，springboot測試類會再啟動一個主類，有時會報單例錯誤

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

使用docker images查看鏡像

[root@localhost commonservice-eureka]# docker images
REPOSITORY             TAG                 IMAGE ID            CREATED             SIZE
commonservice-eureka   latest              e3279c0c77c7        2 minutes ago       693MB
java                   latest              d23bdf5b1b1b        16 months ago       643MB
[root@localhost commonservice-eureka]# 

啟動鏡像

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