## 1.手工方式 ### 1.1.準備Springboot jar專案  將專案打包成jar ### 1.2.編寫Dockerfile ``` FROM java:8 VOLUME /tmp ADD elk-web-1.0-SNAPSHOT.jar elk.jar EXPOSE 8080 ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/elk.jar"] ``` >FROM：表示基礎映象，即執行環境 >VOLUME /tmp建立/tmp目錄並持久化到Docker資料資料夾，因為Spring Boot使用的內嵌Tomcat容器預設使用/tmp作為工作目錄 >ADD：拷貝檔案並且重新命名(ADD elk-web-1.0-SNAPSHOT.jar elk.jar 將應用jar包複製到/elk.jar) >EXPOSE：並不是真正的釋出埠，這個只是容器部署人員與建立image的人員之間的交流，即建立image的人員告訴容器佈署人員容器應該對映哪個埠給外界 >ENTRYPOINT：容器啟動時執行的命令，相當於我們在命令列中輸入java -jar xxxx.jar，為了縮短 Tomcat 的啟動時間，新增java.security.egd的系統屬性指向/dev/urandom作為 ENTRYPOINT ### 1.3.構建容器 ```shell [root@VM_0_15_centos elk]# docker build -t elk .
