## 利用Dockerfile部署SpringBoot项目 ##

### 1、创建一个SpringBooot项目并且打成jar包 ###

![format_png][]

### 2、在Linux中创建一个文件夹，来做docker测试 ###

[root@izwz90lvzs7171wgdhul8az ~]# mkdir /root/docker_test

### 3、将jar包上传到Linux中 ###

创建存放jar包的文件夹

[root@izwz90lvzs7171wgdhul8az docker_test]# mkdir /root/docker_test/jar

然后利用XShell上传jar包到上面的文件夹中

### 4、编写Dockerfile文件 ###

# 基于java镜像创建新镜像
    FROM java:8
    # 作者
    MAINTAINER Howinfun
    # 将jar包添加到容器中并更名为app.jar
    ADD  jar/app.jar /root/docker_test/app.jar
    # 运行jar包
    ENTRYPOINT ["nohup","java","-jar","/root/docker_test/app.jar","&"]

注意：ADD 、 COPY 指令用法一样，唯一不同的是 ADD 支持将归档文件（tar, gzip, bzip2, etc）做提取和解压操作。还有需要注意的是，COPY 指令需要复制的目录一定要放在 Dockerfile 文件的同级目录下。

### 5、制作镜像 ###

[root@izwz90lvzs7171wgdhul8az docker_test]# docker build -t sbdemo .

命令参数：

*  \-t：指定新镜像名
 *  .：表示Dockfile在当前路径

如果我们的 Dockerfile 文件路径不在这个目录下，或者有另外的文件名，我们可以通过 -f 选项单独给出 Dockerfile 文件的路径

[root@izwz90lvzs7171wgdhul8az docker_test]# docker build -t sbdemo -f /root/docker_test/Dockerfile /root/docker_test/

命令参数：

*  \-f：第一个参数是Dockerfile的路径 第二个参数是Dockerfile所在文件夹制作完成后通过docker images命令查看我们制作的镜像：

[root@izwz90lvzs7171wgdhul8az  docker_test]# docker images | grep sbdemo
    sbdemo              latest              7efac46ef997        4 hours ago         686MB

### 6、启动容器 ###

[root@izwz90lvzs7171wgdhul8az docker_test]# docker run -d -p 8888:8888 --name mysbdemo sbdemo:latest

命令参数：

*  \-d：后台运行
 *  \-p：公开指定端口号
 *  –name：给容器命名

启动后可通过docker ps查看正在运行的容器：

[root@izwz90lvzs7171wgdhul8az docker_test]# docker ps
    CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
    5096c8c7b36f        sbdemo              "nohup java -jar /ro??   4 seconds ago       Up 2 seconds        0.0.0.0:8888->8888/tcp   mysbdemo

### 7、查看容器启动日志 ###

我们可以通过 docker logs 查看指定容器的日志：

[root@izwz90lvzs7171wgdhul8az docker_test]# docker logs mysbdemo

### 8、访问接口 ###

容器启动后，我们尝试使用postman或者其他http工具去访问部署在容器中的应用接口。
