【docker】docker部署spring boot项目在服务器上

IDE:idea

工具:docker

spring boot:2.0.1

========================================

简单记录一下流程，以供参考：

第一步：首先得有一个spring boot的项目【集成了jpa+mybatis的spring boot 例子：https://github.com/AngelSXD/swapping】

第二步：项目打包为jar包

install成功以后

找到项目根目录下的target目录，这里面的jar就是打包好可以部署的jar包

第三步：准备服务器和其他的环境，例如mysql数据库，docker

　　进入服务器，【centOS7上安装docker步骤：https://www.cnblogs.com/sxdcgaq8080/p/9178918.html】

　　如果你想在服务器上安装mysql，步骤如下：【https://www.cnblogs.com/sxdcgaq8080/p/9199406.html】

　　【当然，你打包的jar包中，配置文件中连接的数据库的地址需要是你mysql的实际地址，否则数据库连接不上】

第四步：准备服务器上的jar包存放目录以及Dockerfile文件

　　进入服务器，创建你jar包上传到服务器要放的目录，例如：【在linux上创建目录的命令自己查！！】

　　我要将jar包即将放在这个目录下：

　　并且在本目录下创建Dockerfile文件，并且将下面这段粘贴在Dockerfile文件中【使用vi命令即可完成文件的创建以及文件内容的填充】

FROM java:8
VOLUME /temp
ADD swapping.jar swapping.jar
RUN bash -c 'touch /swapping.jar'
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","-Xmx1024m","-Xms1024m","/swapping.jar"]

对于文件内容的解释：【Dockerfile命令解释：http://www.docker.org.cn/dockerppt/114.html】

FROM java:8

指定要构建的spring boot服务镜像的基础源镜像是java，版本是8；如果本地没有java:8的镜像，就会从dockerHub下载。一般首次下载，以后就不会下载了。

VOLUME /temp

VOLUME 指向了容器内的/tmp的目录，由于 Spring Boot 使用内置的Tomcat容器，Tomcat 默认使用/tmp作为工作目录。这个命令的效果是：在宿主机的/var/lib/docker目录下创建一个临时文件并把它链接到容器中的/tmp目录

VOLUME 命令只能指定挂载点，也就是说在此处，只能指定容器内的目录，不能指定宿主机上对应的目录，也就是说是宿主机上自动生成的目录 去挂载了  容器内的指定的/tmp目录！！！
如果想要指定宿主机的目录去进行挂载，只能通过run命令中的 -v参数进行 宿主机的指定目录 挂载  容器内的指定目录

ADD swapping.jar swapping.jar

其实就是 ADD 【rz上传上来的文件】 【要被拷贝到即将要构建的docker容器中的文件】

RUN bash -c 'touch /swapping.jar'

实际执行复制操作的命令

ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","-Xmx1024m","-Xms1024m","/swapping.jar"]

ENTRYPOINT 配置容器启动后执行的命令，并且不可被 docker run 提供的参数覆盖。

-Djava.security.egd=file:/dev/./urandom
添加java.security.egd的系统属性指向/dev/urandom，JVM上的随机数与熵池策略
参考地址：【https://blog.csdn.net/lanmo555/article/details/51909021】

第五步：上传jar包

先修改jar包名字：修改为swapping.jar【文件名需要与Dockerfile文件中配置的一致】

　　使用命令

rz

即可完成jar包上传

注意，

#Dockerfile和jar包放在同一个目录下

第六步：需要进入jar包所在目录，使用jar包创建镜像

　　命令如下：【注意有点哦】

docker build -t swapping .

第七步：运行镜像，启动docker容器

　　最简单的运行命令

docker run --name swapping -itd --net=host  swapping 

　　需要注意spring boot项目的时区问题的启动命令【关于时区处理问题，需要参考：https://www.cnblogs.com/sxdcgaq8080/p/10057385.html】

　　需要注意spring boot项目启动开发配置文件和生产配置文件的配置文件的启动应用【https://www.cnblogs.com/sxdcgaq8080/p/10481974.html】

docker run --name swapping -itd --net=host -v /etc/localtime:/etc/localtime:ro  -v /etc/timezone:/etc/timezone:ro  swapping

　　启动成功后：查看容器启动情况

docker logs -f swapping

退出日志查看 使用

Ctrl+Z

查看启动运行日志如下：

root@wj:/soft/java/dockerJar/swapping# docker logs -f swapping

可以看到启动成功了。

第八步：访问服务看是否正常

接口返回正常

数据库存储正常

好了，服务部署完成拉！！！！！

OK，如果想要重新启动spring boot服务，可以使用命令

docker restart swapping

ok现在，如果代码更新了，想要停止服务，移除springboot服务，重新部署

分别执行如下步骤即可

停止服务

docker stop swapping

移除容器

docker rm -f swapping

移除jar包

rm -f swapping.jar

重新打包【在idea操作，注意配置文件中的连接地址等配置】

【并且注意Dockerfile文件中指定的jar包文件名，需要与上传的jar包文件名一致】

上传jar包

rz

然后重新制作镜像

docker build -t swapping .

启动服务

docker run --name swapping -itd --net=host -v /etc/localtime:/etc/localtime:ro  -v /etc/timezone:/etc/timezone:ro  swapping

即可完成重新部署！！！

当然，你之前构建的镜像文件依旧存在，虽然它不影响你项目的使用，但是你的镜像存在会占据你服务器的空间

所以可以使用命令,查看目前有哪些镜像

docker images

可以使用命令，删除不用的镜像文件

docker rmi 9d3ee8a877d3
