一手動打包測試：
[root@zhaixl1 docker]# ll
總用量 260160
-rw-r--r-- 1 root root 305 12月 22 21:12 Dockerfile
-rw-r--r-- 1 root root 183246769 12月 22 19:53 jdk-8u121-linux-x64.tar.gz
-rw-r--r-- 1 root root 83150458 12月 22 11:48 new_msg_center-0.0.1-SNAPSHOT.jar
# Dockerfile
FROM centos
MAINTAINER zhaixl
ADD jdk-8u121-linux-x64.tar.gz ./
RUN mv jdk1.8.0_121 jdk8
ADD new_msg_center-0.0.1-SNAPSHOT.jar app.jar
ENV JAVA_HOME=/jdk8
ENV PATH=$JAVA_HOME/bin:$PATH
ENV CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
EXPOSE 8081
ENTRYPOINT ["java","-jar","/app.jar"]
[root@zhaixl1 docker]#docker build -t zhaixl/new_messagecenter ./
[root@zhaixl1 docker]#docker run -it -p 8081:8081 -d --name messagecenter3 zhaixl/new_messagecenter
二 maven 自動build Docker Image
1. build Docker Image zhaixl/centos_jdk8
FROM centos
MAINTAINER zhaixl
ADD jdk-8u121-linux-x64.tar.gz ./
RUN mv jdk1.8.0_121 jdk8
ENV JAVA_HOME=/jdk8
ENV PATH=$JAVA_HOME/bin:$PATH
ENV CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
[root@zhaixl1 docker]#docker build -t zhaixl/centos_jdk8 ./
2. maven build Docker Image zhaixl/centos_jdk8
在項目目錄創建Dockerfile文件: src/main/docker/Dockerfile(沒有後綴),內容如下:
#build Docker file
MAINTAINER zhaixl
FROM zhaixl/centos_jdk8
VOLUME /tmp
ADD new_msg_center-0.0.1-SNAPSHOT.jar app.jar
RUN sh -c 'touch /app.jar'
ENV JAVA_OPTS=""
ENTRYPOINT [ "sh", "-c", "java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar /app.jar" ]
#其中 new_msg_center-0.0.1-SNAPSHOT.jar 是項目打包後 /target/ 裏面的文件名
3.在pom文件中添加docker支持
<properties>
<docker.image.prefix>ramer</docker.image.prefix>
</properties>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
<plugin>
<groupId>com.spotify</groupId>
<artifactId>docker-maven-plugin</artifactId>
<version>0.4.11</version>
<configuration>
<imageName>${docker.image.prefix}/${project.artifactId}</imageName>
<dockerDirectory>src/main/docker</dockerDirectory>
<resources>
<resource>
<targetPath>/</targetPath>
<directory>${project.build.directory}</directory>
<include>${project.build.finalName}.jar</include>
</resource>
</resources>
</configuration>
</plugin>
</plugins>
</build>
4.打包,創建鏡像:
mvn package -Dmaven.test.skip=true docker:build
注意: 請確保maven已添加到path中;並且已安裝docker,如果沒有安裝,請訪問: https://www.docker.com/community-edition#/download 下載合適的版本.

6. 運行docker容器
##最好添加--name參數
docker run --name=springboot-docker-demo -p 8081:8081 -it zhaixl/new_msg_center
在瀏覽器訪問: http://192.168.72.11:8081/messagecenter/api/1.0.0/message/getMessage
docker run --name=springboot-docker-demo -p 8081:8081 -it -d zhaixl/new_msg_center
7. 查看正在運行的容器
cmd: docker ps
8. 啓動/關閉/重啓/刪除docker容器
cmd: docker start/stop/restart/rm CONTAINER_ID/NAME
其中:
CONTAINER_ID: 是容器id,執行 docker ps 可查看
NAME: 是容器的名稱,也就是docker run –name後面的名字
