Docker基础（二）

• 编程

容器数据卷

出现的意义：

  • 数据持久化，因为容器删除后，保存在容器中的数据会丢失

  • 方便容器与宿主机数据交互

docker数据类型：

  • 数据卷 ：相当于mount一块磁盘

  • 数据容器：将数据保存在容器上，用于容器间共享数据，这种容器一般不跑应用，只是挂载卷

数据卷

挂载分类

  • 具名挂载

    1. -v 卷名:容器路径

    2. [root@master ~]

    3. f7640ae90c7ec4a2514bc0bf4fb41c156c21d9e5b3ab43aabcba7ed279a9b3df

    4. [root@master ~]

    5. DRIVER VOLUME NAME

    6. local 7a767141bcb3e25b07c67aaad61ffacab081d1b80937fc7b02c3184cd4706b0b

    7. local 7727d1a368eec5721da70bf1af6121065b646a7be02d97b007e9c8b508148029

    8. local test_volume

    9. [root@master ~]

    10. "Mountpoint": "/var/lib/docker/volumes/test_volume/_data",

  • 匿名挂载

    没有指定宿主机目录的，一般默认宿主机路径为/var/lib/docker/volumes/卷名/_data

    1. -v 容器路径

    2. [root@master ~]

    3. c986f508b492e8327a0916c54f824f2f46490f50674fd0ef6c2303d369a304ad

  • 指定宿主机路径挂载

    1. -v 宿主机路径:容器路径

扩展


 
 
    
  
  
  1.     
  2. -v 宿主机路径:容器路径:ro

测试一：挂载centos镜像


 
 
    
  
  
  1. [root@master ~]    
  2. [root@master centos_tmp]    
  3. CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
    4. 
  
  
  4. c475662fa21b centos:latest "/bin/bash" 4 minutes ago Up 4 minutes silly_hamilton
    5.

  6. [root@master centos_tmp]    
  7.  "Mounts": [

分别在容器外创建文件、容器内创建文件验证：

DockerFile

构建步骤

  1. 编写dockerfile

  2. docker build

  3. docker run

  4. dockers push

基础语法

  • 每个指令（关键字）必须大写

  • 从上到下，顺序执行

  • 注释用

  • 每一个指令都创建一个镜像层并提交

常用命令


 
 
    
  
  
  1. FROM     
  2. MAINTAINER     
  3. ADD     
  4. COPY     
  5. RUN     
  6. CMD     
  7. ENTRYPOINT     
  8. ONBUILD     
  9. ENV     
  10. WORKDIR     
  11. EXPOSE     
  12. VOLUME

CMD和ENTRYPOINT的区别:

  1. 编写两个dockersfile


 
 
    
  
  
  1. [root@master docker_file]    
  2. FROM centos
    3. 
  
  
  
  
  3. MAINTAINER yiyu
    4. 
  
  
  
  
  4. CMD ["ls","-a"]
    5. 
  
  
  5. [root@master docker_file]    
  6. FROM centos
    7. 
  
  
  
  
  7. MAINTAINER yiyu
    8. 
  
  
  
  
  8. ENTRYPOINT ["ls","-a"]
    9. 
  
  
  9. [root@master docker_file]  
  
        
  1.  2. 分别编译生成镜像
    2. 
 
 

 
 
    
  
  
  1. [root@master docker_file]    
  2. [root@master docker_file]    
  3. [root@master docker_file]  
  
        
  1.  3. 查看镜像列表

  1. 结论：从上可以看出，启动时添加的-a，会把CMD中的参数全部替换掉，转而把你输入的参数当成命令去执行，而会在ENTRYPOINT的参数后面是添加。即-l和ls -a -l的区别。

实例1：制作centos镜像


 
 
    
  
  
  1.     
  2. [root@master ~]    
  3. yiyu/centos 1.0 a4d1fa934530 23 hours ago 231MB
    4. 
  
  
  4. centos latest 5d0da3dc9764 2 months ago 231MB
    5.

1.编写dockerfile


 
 
    
  
  
  1. [root@master docker_file]    
  2. MAINTAINER yiyu
    3. 
  
  
  
  
  3. ENV default_path="/usr/local/bin"
    4. 
  
  
  
  
  4. WORKDIR $default_path
    5. 
  
  
  
  
  5. RUN yum install -y perf
    6. 
  
  
  6. RUN yum install -y net-tools
    7. 
  
  
  
  
  7. EXPOSE 8080
    8. 
  
  
  
  
  8. CMD echo "$default_path"
    9. 
  
  
  9. CMD /bin/bash
    10.

  1. 构建dockerfile，看到最后的两个successfully就说明构建成功了


 
 
    
  
  
  1. [root@master docker_file]    
  2. Sending build context to Docker daemon 3.072kB
    3. 
  
  
  3. Step 1/9 : FROM yiyu/centos:1.0
    4. 
  
  
  4. ...
    5. 
  
  
  5. Successfully built 3e8d28433743
    6. 
  
  
  6. Successfully tagged mycentos:1.0
    7. 
  
  
  7.     
  8. [root@master docker_file]    
  9. mycentos 1.0 3e8d28433743 46 seconds ago 371MB
    10. 
  
  
  10. yiyu/centos 1.0 a4d1fa934530 23 hours ago 231MB
    11. 
  
  
  11. centos latest 5d0da3dc9764 2 months ago 231MB
    12.

  1. 分别启动 yiyu/centos:1.0 和 mycentos:1.0 对比，发现前者无perf和ifconfig命令，后者有


 
 
    
  
  
  1.     
  2. [root@master docker_file]    
  3. [root@aaf5b20b026f /]    
  4. bash: perf: command not found
    5. 
  
  
  5. [root@aaf5b20b026f /]    
  6. bash: ifconfig: command not found

  10. [root@49812951c620 bin]        
  11.  usage: perf [--version] [--help] [OPTIONS] COMMAND [ARGS]
    12.
