1、Docker简介

1.1、Docker为什么会出现？

避免开发和运维打架^__

1.2、Docker理念

一次封装，到处运行

1.3、是什么？

解决了运行环境和配置问题，方便做持续集成并有助于整体发布的容器虚拟化技术

2、Docker能干什么？

2.1、容器虚拟化

2.2、 一次构建、随处运行

更快速的应用交付和部署更便捷的升级和扩缩容更简单的系统运维更高效的计算资源利用

3、Docker安装

3.1、前提说明

系统和内核版本的限制 去官网看一下 uname -r 3.10.0-1127.el7.x86_64 cat /etc/redhat-release CentOS Linux release 7.8.2003 (Core)

3.2、Docker的基本组成

镜像

       Docker镜像（image）就是一个只读的模板。镜像可以用来创建Docker容器，一个镜像可以创建很多容器。

Docker面向对象容器对象镜像类 容器

       Docker利用容器（Container）独立运行的一个或一组应用。容器是用镜像创建的运行实例        容器可以被启动、开始、停止、删除。每个容器都是互相隔离的、保证安全的平台        可以把容器看做一个简易版的Linux环境（包括root用户权限、进程空间、用户空间和网络空间）和运行在其中的应用程序。        容器的定义和镜像几乎一模一样，也就是一堆层的统一视角，唯一的区别在于容器的最上边的那一层是可读可写的

仓库(Repository)

       仓库是集中存放镜像文件的场所        仓库和仓库注册服务器(Registry)是有区别的。仓库注册服务器上往往存放着许多仓库，每个仓库中又包含多个镜像，每个镜像有不同的标签(tag)。

总结

3.4、永远的HelloWorld

10. 测试 docker run hello-world(镜像名) ------------------------------------------------------ Unable to find image 'hello-world:latest' locally latest: Pulling from library/hello-world 0e03bdcc26d7: Pull complete Digest: sha256:8c5aeeb6a5f3ba4883347d3747a7249f491766ca1caa47e5da5dfcf6b9b717c0 Status: Downloaded newer image for hello-world:latest Hello from Docker! This message shows that your installation appears to be working correctly. To generate this message, Docker took the following steps: 1. The Docker client contacted the Docker daemon. 2. The Docker daemon pulled the "hello-world" image from the Docker Hub. (amd64) 3. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. 4. The Docker daemon streamed that output to the Docker client, which sent it to your terminal. To try something more ambitious, you can run an Ubuntu container with: $ docker run -it ubuntu bash Share images, automate workflows, and more with a free Docker ID: https://hub.docker.com/ For more examples and ideas, visit: https://docs.docker.com/get-started/

3.5、阿里云镜像加速

https://cr.console.aliyun.com/cn-qingdao/instances/mirrors sudo mkdir -p /etc/docker sudo tee /etc/docker/daemon.json <<-'EOF' { "registry-mirrors": ["https://o66gqcsszc.mirror.aliyuncs.com"] (//后面的写自己的，这个是错的) } EOF sudo systemctl daemon-reload sudo systemctl restart docker

5、容器数据卷

5.1、是什么？

有点类似我们Redis里面的rdb和aof文件

5.2、能干什么？

容器的持久化 容器间的继承+共享数据 <!-- --> 卷就是目录或文件，存在于一个或多个容器中，由docker挂载到容器，但不属于联合文件系统，因此能绕过UnionFS 提供一些用于持续存储或共享数据的特性 卷的设计目的就是数据的持久化，完全独立于容器的生存周期，因此Docker不会在容器删除时删除其挂载的数据卷 <!-- 特点 --> 1 数据卷可在容器之间共享或重用数据 2 卷中的更改可以直接生效 3 数据卷中的更改不会包含在镜像的更新中 4 数据卷的生命周期一直持续到没有容器使用它为止

5.3、数据卷

## 容器内添加 #1 直接命令添加 docker run -it -v /宿主机绝对路径:/容器内目录 镜像名 docker run -it -v /myDataVolume:/dataVolumeContainer centos docker run -it -v /宿主机绝对路径:/容器内目录:ro 镜像名 ## 只支持主机单向修改，容器只能读 #2 DockerFile添加 通过镜像描述文件来创建自己的镜像，当然就可以在创建的时候，先指定镜像共享文件路径

5.4、数据卷容器

## 数据的继承和共享 ## 数据的持久化 -------------------------------- ########################创建DockerFile################### FROM centos VOLUME ["/dataVolumeContainer1","/dataVolumeContainer2"] ## docker会自动在宿主机上新建数据卷的持久化目录 通过 docker inspect 容器名 来查看路径 CMD echo "finshed,--------success1" CMD /bin/bash -------------------------------- # 通过DockerFile来创建镜像 -------------------------------- docker build -f /mydocker/DockerFile -t **/centos -------------------------------- #通过DockerFile创建镜像启动容器 docker run -it --name dc01 **/centos dc02&&dc03 继承dc01 docker run -it --name dc02 --volumes-from dc01 **/centos docker run -it --name dc03 --volumes-from dc01 **/centos 在dc01的数据卷创建文件，把dc01退出，dc02\dc03上都会有，如果再把dc02退出，dc03上也有 ###############数据卷的生命周期 直到没有容器去使用######################

6、DockerFile解析

6.1、是什么？

DockerFile 是用来构建Docker镜像的构建文件，是由一系列命令和参数构建的脚本 通过配置文件描述镜像，可以构建自己的镜像

6.2、DockerFile构建过程 解析

基础知识 每条保留字指令都必须为大写字母且后面跟随至少一个参数 指令按照从上到下，顺序执行 #表示注释 每条指令都会创建一个新的镜像层，并对镜像进行提交 Docker执行DockerFile的大致步骤 docker从基础镜像运行一个容器 执行一条指令并对容器做出修改 执行类似 docker commit的操作提交一个新的镜像层 docker再基于刚提交的镜像运行一个新容器 执行dockerfile中的下一条指令直到所有指令执行完成 总结 DockerFile是软件的原材料 Docker镜像是软件的交付品 Docker容器可以认为是软件的运行态 DockerFile面向开发，Docker镜像成为交付标准，Docker容器则涉及部署与运维，三者缺一不可，合力充当Docker体系的基石

6.3、保留字指令

ADD 后面的URL和压缩包，docker会自动解析、解压 COPY 如果后面直接跟压缩包会出问题，不会自动解压 CMD 后面指定的命令，最终只有最后一个命令会执行 ENTRYPOINT 后面的命令属于追加 ONBUILD 一旦镜像被继承，则触发后面指令 EXPOSE 对外暴露接口 ENV 在构建镜像过程中，设置环境变量 WORKDIR 一登录所在的目录

7、自定义镜像mycentos

7.1、centos案例

编写DockerFile配置 ## /mydocker/DockerFile2 FROM centos MAINTAINER **<**@gmail.com> ENV MYPATH /usr/local WORKDIR $MYPATH RUN yum -y install vim RUN yum -y install net-tools EXPOSE 80 CMD echo $MYPATH CMD echo "success------------ok" CMD /bin/bash build配置文件 docker build -f /mydocker/DockerFile2 -t mycentos:1.3 . 运行images docker run -it mycentos:1.3

7.2、CMD/ENTRYPOINT

docekr run -it -p 7777:8080 ### CMD 在Dockerfile最后 CMD 后面跟着命令 如果run 一个镜像实例，在后面添加参数时，会报错，因为会把CMD后加的 命令覆盖，而run的时候加的参数根本不是命令，所以会报错 ### ENTRYPOINT 在Dockerfile最后 ENTRYPOINT 后面跟着命令 如果run 一个镜像实例，在后面添加参数时,docker会默认将参数 追加到 ENTRYPOINT 后面跟着的命令后，作为一个参数，这样命令就更强大了

7.3、ONBUILD

FROM centos RUN yum install -y curl ENTRYPOINT ["curl","-s","http://ip.cn"] ONBUILD RUN echo "father onbuild------------886" ## 如果有其他镜像要基于上面镜像进行构建，在build时，会触发ONBUILD后面的命令

7.4、自定义Tomcat

创建Dockerfile # /mydocker/tomcat vim Dockerfile FROM centos MAINTAINER h**<***@gmail.com> #把宿主机当前上下文的c.txt拷贝到容器 /usr/local路径下 COPY c.txt /usr/local/cincontainer.txt ADD jdk-8u202-linux-x64.tar.gz /usr/local/ ADD apache-tomcat-8.5.58.tar.gz /usr/local/ # 安装vim编辑器 RUN yum -y install vim #设置工作访问时候的WORKDIR路径，登录落脚点 ENV MYPATH /usr/local WORKDIR $MYPATH #配置java与tomcat环境变量 ENV JAVA_HOME /usr/local/jdk1.8.0_202 ENV CLASSPATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar ENV CATALINA_HOME /usr/local/apache-tomcat-8.5.58 ENV CATALINA_BASE /usr/local/apache-tomcat-8.5.58 ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/lib:$CATALINA_HOME/bin #容器运行时监听的端口 EXPOSE 8080 #启动时运行tomcat #ENTRYPOINT ["/usr/local/apache-tomcat-8.5.58/bin/startup.sh"] #CMD["/usr/local/apache-tomcat-8.5.58/bin/catalina.sh","run"] CMD /usr/local/apache-tomcat-8.5.58/bin/startup.sh && tail -F /usr/local/apache-tomcat-8.5.58/bin/logs/catalina.out 构建 ## /mydocker/tomcat docker build -t *tomcat8 . 运行 docker run -d -p 9080:8080 --name myt8 -v /mydocker/tomcat/test:/usr/local/apache-tomcat-8.5.58/webapps/test -v /mydocker/tomcat/tomcatlogs/:/usr/local/apache-tomcat-8.5.58/logs --privileged=true **tomcat8:latest

运行下面的命令

docker run -d -p 9080:8080 --name myt8 -v /mydocker/tomcat/test:/usr/local/apache-tomcat-8.5.58/webapps/test -v /mydocker/tomcat/tomcatlogs/:/usr/local/apache-tomcat-8.5.58/logs --privileged=true **tomcat8:latest

7.5、在的定义的tomcat中发布web服务

## /mydocker/tomcat/test mkdir WEB-INF cd WEB-INF vim web.xml ------------ ------------ cd .. vim index.jsp ----------- ----------- <!-- web.xml --> <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" > <web-app> <display-name>Archetype Created Web Application</display-name> </web-app> <!-- index.jsp --> <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" isELIgnored="false" %> <html> <head> <title>Title</title> </head> <body> <div style="width:270px;height: 30px"><font color="red">${errMsg}</font></div> <%="i am in docker tomcat self"%> <form action="transfer.action" method="post"> dst:<input type="text" name="outName"><br/> goal:<input type="text" name="inName"><br/> money:<input type="text" name="money"><br/> <input type="submit" value="ok"/> </form> <%System.out.printlin("=============docaker tomcat self");%> </body> </html> docker exec 2ebfdba94b30 ls -l /usr/local/apache-tomcat-8.5.58/webapps/test drwxr-xr-x. 2 root root 21 Oct 19 15:15 WEB-INF -rw-r--r--. 1 root root 623 Oct 19 15:15 index.jsp ##重启容器 docker restart 容器名

8、Docker常用安装

8.1、总体步骤

8.2、安装tomcat

8.3、安装mysql

搜索镜像 docker search mysql 拉取镜像 docker pull mysql:5.6 运行镜像 docker run -p 12345:3306 --name mysql -v /mydocker/mysql/conf:/etc/mysql/conf.d -v /mydocker/mysql/logs:/logs -v /mydocker/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -d mysql:5.6 docker run -p 12345:3306 --name mysql -v /mydocker/mysql/conf:/etc/mysql/conf.d -v /mydocker/mysql/logs:/logs -v /mydocker/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -d mysql:5.6 外部win10连接运行在docker上的mysql服务数据备份 docker exec 容器ID sh -c ' exec mysqldump --all-databases -uroot -p"123456" ' > /mydocker/mysql/all.sql

8.4、安装Redis

拉取镜像 docker pull redis:3.2 启动redis docker run -p 6379:6379 -v /mydocker/myredis/data:/data -v /mydocker/myredis/conf/redis.conf:/usr/local/etc/redis/redis.conf -d redis:3.2 redis-server /usr/local/etc/redis/redis.conf --appendonly yes docker run -p 6379:6379 -v /mydocker/myredis/data:/data -v /mydocker/myredis/conf/redis.conf:/usr/local/etc/redis/redis.conf -d redis:3.2 redis-server /usr/local/etc/redis/redis.conf --appendonly yes 创建配置文件 vim /mydocker/myredis/conf/redis.conf/redis.conf

9、PUSH到阿里云仓库

9.1、镜像生成的方法

通过DockerFile生成从容器创建一个新的镜像 docker commit -a "yhw" -m "new mycentos with vim and ifconfig" 正在运行的容器id 新的镜像名:tag

9.2、将本地镜像推送到阿里云

$ sudo docker login --username=**********@qq.com registry.cn-shanghai.aliyuncs.com $ sudo docker tag [ImageId] registry.cn-shanghai.aliyuncs.com/***/mycentos:[镜像版本号] $ sudo docker push registry.cn-shanghai.aliyuncs.com/**/mycentos:[镜像版本号] docker login --username=*******@qq.com registry.cn-shanghai.aliyuncs.com docker tag 1e4bf6b2ed06 registry.cn-shanghai.aliyuncs.com/***/mycentos:1.0 docker push registry.cn-shanghai.aliyuncs.com/***/mycentos:[镜像版本号]
