Docker3-Dockerfile创建镜像的方法（推荐docker file这种方法）

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 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 　　　　　　
　　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　　　
　　例子：MAINTAINER zxg [email protected]
　　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。

　　
5、EXPOSE　　[...]
　　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

6、ENV
　　ENV  
　　ENV =。。。
　　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
　　
7、ADD
　　ADD ...
　　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

　　
8、COPY
　　COPY ...
　　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。
9、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

10、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
11、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

12、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  
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 80
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  .
