一、镜像制作的方法

  1、本地导入导出镜像

    请参考:Docker 架构原理及简单使用

导出:docker  save nginx >/tmp/nginx.tar.gz
导入:docker load </tmp/nginx.tar.gz

  2、docker commit 命令创建镜像副本

    请参考:Docker docker commit方法镜像制作

  3、docker file

    前面两种方法已经介绍过了,这里介绍docker file,生成环境推荐使用这种方法

二、docker file方法制作镜像

  1、什么是docker file

    用来全自动构建镜像文件,命名为Dockerfile

  2、Dockerfile 文件编写指令及语法

    1)指令

FROM       
MAINTAINER   
RUN       
CMD      
EXPOSE
ENV
ADD
COPY
ENTRYPOINT
VOLUME
USER
WORKDIR
ONBUILD

    2)语法

    引用了docker中文文档:http://www.docker.org.cn/dockerppt/114.html

1、FROM       <image>
  例子:FROM centos
  FROM指定构建镜像的基础源镜像,如果本地没有指定的镜像,则会自动从Docker的公共库pull镜像下来。
  FROM必须是Dockerfile中非注释行的第一个指令,即一个Dockerfile从FROM语句开始
  FROM可以在一个DOCKERfile中出现多次,如果有需求在一个Dockerfile中创建多个镜像
2、MAINTAINER   <name>
  例子:MAINTAINER zxg zhutoyearn@163.com
  指定创建镜像的用户
3、RUN       <"executable","parm1","param2">
  两种使用方式:
  • RUN
  • RUN  "executable", "param1", "param2"
  例子:RUN yum install wget -y

  每条RUN指令将在当前镜像基础上执行指定命令,并提交为新的镜像,后续的RUN都在之前RUN提交后的镜像为基础,镜像是分层的,可以通过一个镜像的任何一个历史提交点来创建,类似源码的 版本控制 。

  exec 方式会被解析为一个 JSON 数组,所以必须使用双引号而不是单引号。exec 方式不会调用一个命令 shell,所以也就不会继承相应的变量,如:

    RUN [ "echo", "$HOME" ]  #错误,这个个方法不会输出HOME变量,下面为正确方式
    RUN [ "sh", "-c", "echo", "$HOME" ]
 RUN 产生的缓存在下一次构建的适合是不会失效的,会被重用,可以使用--no-cache选择,即docker build-no-cache,如此便不会缓存

4、CMD       <"executable",>
 三种使用方式:
  • CMD  "executable","param1","param2"
  • CMD  "param1","param2"
  • CMD command param1 param2 (shell form)
 例子:CMD["nginx"] 

CMD指定在 Dockerfile 中只能使用一次,如果有多个,则只有最后一个会生效。

CMD的目的是为了在启动容器时提供一个默认的命令执行选项。如果用户启动容器时指定了运行的命令,则会覆盖掉CMD指定的命令。

CMD会在启动容器的时候执行,build 时不执行,而RUN只是在构建镜像的时候执行,后续镜像构建完成之后,启动容器就与RUN无关了,这个初学者容易弄混这个概念,这里简单注解一下。

  
、EXPOSE  <port>[<port>...]
  告诉docker服务端容器对外映射的本地端口,需要在docker run的使用使用-p或者-P选项生效   例子:EXPOSE 80
、ENV
  ENV <key> <value>
  ENV <key>=<value>。。。
  指定一个环节变量,会被后续RUN指令使用,并在容器运行时保留   例子:ENV myname zxg
     ENV myhome beijing
     ENV myname="zxg" myhome=beijing
  
、ADD
  ADD <src>...<dest>
  ADD复制本地主机文件、目录或者远程文件URLS从并且添加到容器指定路径中
  支持通过Go的正则模式匹配,具体规则可参见Go filepath.Match   例子:ADD hom* /mydir/  #adds all files starting with ”hom“
     ADD hom?.txt /mydir/ #?is replaced with any single character
    ADD index.html /usr/share/nginx/html/index.html

  注意如下:
  • 路径必须是绝对路径,如果 不存在,会自动创建对应目录
  • 路径必须是 Dockerfile 所在路径的相对路径
  • 如果是一个目录,只会复制目录下的内容,而目录本身则不会被复制
  
、COPY
  COPY <src>...<dest>
  COPY复制新文件或者目录并且添加到容器指定路径中,用法和ADD相同,唯一区别时不能指定远程文件URLS。
、ENTRYPOINT
  ENTRYPOINT "executable","param1","param2"
  ENTRYPOINT command param1 param2(shell form)

    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,而CMD是可以被覆盖的。如果需要覆盖,则可以使用docker run --entrypoint选项。

    每个 Dockerfile 中只能有一个ENTRYPOINT,当指定多个时,只有最后一个生效。

    Exec form ENTRYPOINT 例子

    通过ENTRYPOINT使用 exec form 方式设置稳定的默认命令和选项,而使用CMD添加默认之外经常被改动的选项。

    FROM ubuntu
    ENTRYPOINT ["top", "-b"]
    CMD ["-c"]

    通过 Dockerfile 使用ENTRYPOINT展示前台运行 Apache 服务

    FROM debian:stable
    RUN apt-get update && apt-get install -y --force-yes apache2
    EXPOSE 80 443
    VOLUME ["/var/www", "/var/log/apache2", "/etc/apache2"]
    ENTRYPOINT ["/usr/sbin/apache2ctl", "-D", "FOREGROUND"]

    Shell form ENTRYPOINT 例子

    这种方式会在/bin/sh -c中执行,会忽略任何CMD或者docker run命令行选项,为了确保docker stop能够停止长时间运行ENTRYPOINT的容器,确保执行的时候使用exec选项。

    FROM ubuntu
    ENTRYPOINT exec top -b

    如果在ENTRYPOINT忘记使用exec选项,则可以使用CMD补上:

    FROM ubuntu
    ENTRYPOINT top -b
    CMD --ignored-param1 # --ignored-param2 ... --ignored-param3 ... 依此类推

、VOLUME 
  VOLUME ["/data"]
  创建一个可以从本地主机或其他容器挂载的挂载点,后续具体介绍
、USER
  USER daemon
  指定运行容器时的用户名或UID,后续RUN、CMD、ENTERPOINT也会使用指定用户 、WORKDIR
 WORKDIR /path/to/workdir
  为后续的RUN、CMD、ENTRYPOINT指令配置工作目录。可以使用多个WORKDIR指令,后续命令如果参数是相对路径,则会基于之前命令指定的路径
  WORKDIR /a
  WORKDIR b
  WORKDIR c
  RUN pwd
  最终路径是/a/b/c
  WORKDIR指令可以在ENV设置变量之后调用环境变量:
  ENV DIRPATH /path
  WORKDIR $DIRPATH/$DIRNAME
  最终路径则为 /path/$DIRNAME
13、ONBUILD
  ONBUILD [INSTRUCTION]
  配置当所创建的镜像作为其他新创建镜像的基础镜像时,所执行的操作指令
  例如:Dockerfile 使用如下的内容创建了镜像image-A:
    [...]
    ONBUILD ADD . /app/src
    ONBUILD RUN /usr/local/bin/python-build --dri /app/src
    [...]
  

  3、例子examples,做一个centos安装了nginx及wget的镜像

[root@web1 docker]# vim Dockerfile
#this is docker file for centos-nginx
FROM centos
MAINTAINER zxg <victor@docker.com>
RUN yum install wget -y
RUN rpm -ivh https://mirrors.aliyun.com/epel/epel-release-latest-7.noarch.rpm
N yum install nginx -y
▽DD index.html /usr/share/nginx/html/index.html
RUN echo "daemon off;">>/etc/nginx/nginx.conf
EXPOSE
CMD ["nginx"]

  4、使用build命令制作镜像

   1)build命令说明

$ docker build --help
Usage: docker build [OPTIONS] PATH | URL | -
Build a new image from the source code at PATH
--force-rm=false Always remove intermediate containers, even after unsuccessful builds # 移除过渡容器,即使构建失败
--no-cache=false Do not use cache when building the image # 不实用 cache
-q, --quiet=false Suppress the verbose output generated by the containers
--rm=true Remove intermediate containers after a successful build # 构建成功后移除过渡层容器
-t, --tag="" Repository name (and optionally a tag) to be applied to the resulting image in case of success

    2)制作镜像

   docker build -t zxg/nginx1 .

   整个过程还挺长,所以折叠了,可以点开看一下

[root@web1 docker]# docker build -t zxg/nginx1  .
