springboot2.X打包docker容器部署

# **1.创建项目** #

使用idea创建springboot项目

项目地址: [springboot-docker-demo][]

创建好之后,在pom.xml中添加docker的build工具

这里需要服务器docker开通远程访问端口(下面有开通方法),用于项目docker镜像的打包上传

dockerHost  docker服务器地址

imageName 镜像名称+版本号

<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>1.0.0 </version> 
       <configuration> 
        
       <dockerHost>http://192.168.112.135:2375 </dockerHost> 
        
       <imageName>demo:1.0.0 </imageName> 
        
       <forceTags>true </forceTags> 
        
       <dockerDirectory>${project.basedir}/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>

接下来在项目的 src/java/main 目录下创建 docker/Dockerfile 结构如下

Dockerfile文件内容为

# 父镜像 
       FROM lion_li/jdk: 8 
       
       MAINTAINER Lion Li 
       
       VOLUME /root 
       # 添加jar包到容器并重命名 
       ADD docker-demo- 0. 0. 1-SNAPSHOT.jar demo.jar 
       
       RUN bash -c 'touch /demo.jar' 
       # 同步容器与本机时间 
       RUN cp /usr/share/zoneinfo/Asia/Shanghai /etc/ localtime \ 
       && echo 'Asia/Shanghai' > /etc/timezone 
       # 使用端口 
       EXPOSE 8080 
       
       ENV JAVA_OPTS= "-Xms256m -Xmx256m" 
       
       # -Djava.security.egd=file:/dev/./urandom 加速tomcat启动 
       # -Dspring.profiles.active=prod 指定spring运行环境,不用可以删除 
       ENTRYPOINT [ "sh", "-c", "java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -Dspring.profiles.active=prod -jar /demo.jar"]

lion\_li/jdk:8  该镜像为本人搭建的oracle jdk镜像 也可以使用 openjdk镜像  java:8

如需oracle jdk镜像请参考本人的另一篇文章: [docker 搭建 oracle jdk(版本可更换) 镜像][docker _ oracle jdk_]

# **2.构建镜像** #

使用maven打包工具打包

使用docker工具构建镜像并上传服务器

此操作需要服务器docker开通远程访问端口

可以参考本人的另一篇文章: [docker 开启端口 2375 供外部程序访问][docker _ 2375]

查看镜像

docker images

![20190618134510947.png][]

上传成功

再次执行,docker会把名称赋值给我们较新的镜像,原先较旧的镜像也不会覆盖,而是会变为一个无名镜像

将无名镜像删除即可

可以参考我的另一篇文章: [docker 删除 容器/镜像 方法][docker _ _]

# **3.生成容器** #

创建容器

docker run -d --name demo -p 8080:8080 -t demo:1.0.0

查看所有容器

docker ps -a

![20190618135118152.png][]

创建成功,运行容器

docker start demo

# **4.查看springboot docker容器运行日志** #

docker logs -f -t --tail 行数 容器名

docker logs -f -t --tail 50 demo

# **5.测试** #

访问insert接口

![2019061814070023.png][]

访问查询接口

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MDQ2MTI4MQ_size_16_color_FFFFFF_t_70 4][]
