docker服務器的安裝部署java
一、Docker 要求 CentOS 系統的內核版本高於 3.10 ,驗證CentOS 版本是否支持 Docker 。linux
root@bogon ~]# uname -r
二、更新yum包到最新spring
root@bogon ~]# sudo yum update
三、卸載舊版本docker
[root@bogon ~]# sudo yum remove docker docker-common docker-selinux docker-engine
四、設置yum源apache
[root@bogon ~]# sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
五、安裝dockercentos
[root@bogon ~]# sudo yum install docker-ce
六、啓動並加入開機啓動springboot
[root@bogon ~]# sudo systemctl start docker [root@bogon ~]# sudo systemctl enable docker
七、驗證是否安裝成功服務器
[root@bogon ~]# docker version
因爲安裝過於簡單,自行百度微信

進入項目目錄,運行 mvn clean package docker:build -DskipTests 架構
注: -DskipTests 爲跳過測試,springboot測試類會再啓動一個主類,有時會報單例錯誤
[root@localhost Downloads]# cd commonservice-eureka [root@localhost commonservice-eureka]# mvn clean package docker:build -DskipTests //如下爲輸出日誌: Digest: sha256:c1ff613e8ba25833d2e1940da0940c3824f03f802c449f3d1815a66b7f8c0e9d Status: Downloaded newer image for java:latest ---> d23bdf5b1b1b Step 2/3 : ADD /commonservice-eureka-0.0.1-SNAPSHOT.jar // ---> b796a24d8225 Step 3/3 : ENTRYPOINT ["java", "-jar", "/commonservice-eureka-0.0.1-SNAPSHOT.jar"] ---> Running in b488f35f00dd Removing intermediate container b488f35f00dd ---> e3279c0c77c7 ProgressMessage{id=null, status=null, stream=null, error=null, progress=null, progressDetail=null} Successfully built e3279c0c77c7 Successfully tagged commonservice-eureka:latest [INFO] Built commonservice-eureka [INFO] ------------------------------------------------------------------------ [INFO] BUILD SUCCESS [INFO] ------------------------------------------------------------------------ [INFO] Total time: 15:49 min [INFO] Finished at: 2018-05-25T02:34:34-07:00 [INFO] -----------------------------------------------------------------------
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]#
啓動鏡像
[root@localhost commonservice-eureka]# docker run -p 8761:8761 commonservice-eureka
