Docker容器化技术入门

Docker入门

本人环境搭建在内网树莓派4b上，使用的linux发行版为树莓派Ubuntu 21.04 server版本

一些镜像需要根据自己的处理器架构去修改！！！

安装Docker

sudo apt install docker.io

查看安装的docker是否成功

root@ubuntu:/home/ubuntu# docker version

Docker HelloWorld

使用pull命令吧hello-world镜像pull下来

使用docker pull --help得到pull的使用文档可知

pull 用法Usage: docker pull [OPTIONS] NAME[:TAG|@DIGEST]

sudo docker pull hello-world:latest      #latest可以不加，默认会pull最新版

使用run命令吧hello-world跑起来

sudo docker run hello-world

root@ubuntu:/home/ubuntu# sudo docker run hello-worldHello 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.(arm64v8)3. The Docker daemon created a new container from that image which runs theexecutable that produces the output you are currently reading.4. The Docker daemon streamed that output to the Docker client, which sent itto your terminal.To try something more ambitious, you can run an Ubuntu container with:$ docker run -it ubuntu bashShare 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/

可以看出我们的docker安装成功，测试hello-world也成功了

当然，我们可以不用pull命令，直接使用run命令来运行一个镜像。docker在检索宿主机中没有hello-world镜像后会去官方镜像仓库pull下来再运行

sudo  docker run hello-world:latest

Docker run 的底层原理图

Docker命令

镜像命令

docker images 查看所有本地主机上的镜像

docker search 查找镜像

比如我们需要查找mysql镜像

sudo docker search mysql

我们会发现符合名称为mysql的镜像太多了，可以使用STARS数量来过滤一部分镜像

docker search mysql --filter=STARS=3000NAME      DESCRIPTION                                     STARS     OFFICIAL   AUTOMATEDmysql     MySQL is a widely used, open-source relation…   12191     [OK]       mariadb   MariaDB Server is a high performing open sou…   4683      [OK]

也可以使用OFFICIAL参数来查找出全部的官方镜像 --filter “is-official=true”

docker search mysql --filter "is-official=true"NAME         DESCRIPTION                                     STARS     OFFICIAL   AUTOMATEDmysql        MySQL is a widely used, open-source relation…   12191     [OK]       mariadb      MariaDB Server is a high performing open sou…   4683      [OK]       percona      Percona Server is a fork of the MySQL relati…   570       [OK]       phpmyadmin   phpMyAdmin - A web interface for MySQL and M…   461       [OK]

当然，使用命令行search查找镜像不如去官方网站去查找(http://hub.docker.com)，上面有不同的镜像和版本的介绍和帮助文档，在网站中找到合适的镜像再pull到本地是最好的

docker pull 下载镜像

这个命令在我们运行hello-world镜像时候说过了

我们再次pull一个mysql来使用（注意问题，我的架构是树莓派的armv8架构，直接使用pull mysql下来的是x86/64架构的镜像，不能运行）

我们到官方镜像网站去查询mysql镜像https://hub.docker.com/

排名最前面的mysql我们点进去查看，发现能找到的版本都不支持armv8架构

这时我们去查看下官方文档

能看到有支持armv8架构的mysql 的超链接，点过去

找到了一个最新版本为mysql:oracle版本的mysql，支持的架构中有我们树莓派4b的架构

# docker pull mysql# Using default tag: latest           # 如果不写tag，默认就是latest 我们这里不能使用正常版本的mysql，必须修改后缀为oracleroot@ubuntu:/# sudo docker pull mysql:oracleoracle: Pulling from library/mysql63ea605e0f83: Pull complete 8682e4307360: Pull complete 8811e76642f8: Pull complete 04ed278df250: Pull complete 2c93b01f7b04: Pull complete 13a0806a1841: Pull complete dc52d9a5079e: Pull complete 4efb38734b87: Pull complete 98e25dd4e90f: Pull complete 142127aec3b2: Pull complete Digest: sha256:c290ae4835977163f5e64f0097ca8e3e68b7bfe8e1be6eaf868cd2c784f49a61Status: Downloaded newer image for mysql:oracledocker.io/library/mysql:oracle

docker rmi 删除镜像

docker rmi -f [镜像id]                        # 删除指定镜像docker rmi -f [镜像id1] [镜像id2] [镜像id3]    # 删除多个镜像docker rmi -f $(docker images -aq)            # 删除所有镜像

容器命令

容器是在镜像基础上的，有镜像了才能有对应的容器。镜像和容器是层级关系，镜像生成容器，我们操作的层级是容器

我们pull一个centos镜像

sudo docker pull centos

docker run 运行命令

docker run [可选参数] 镜像名 [命令] [文件扩展名]可选参数：-a stdin: 指定标准输入输出内容类型，可选 STDIN/STDOUT/STDERR 三项；-d: 后台运行容器，并返回容器ID；-i: 以交互模式运行容器，通常与 -t 同时使用；-P: 随机端口映射，容器内部端口随机映射到主机的端口-p: 指定端口映射，格式为：主机(宿主)端口:容器端口-t: 为容器重新分配一个伪输入终端，通常与 -i 同时使用；--name="nginx-lb": 为容器指定一个名称；--dns 8.8.8.8: 指定容器使用的DNS服务器，默认和宿主一致；--dns-search example.com: 指定容器DNS搜索域名，默认和宿主一致；-h "mars": 指定容器的hostname；-e username="ritchie": 设置环境变量；--env-file=[]: 从指定文件读入环境变量；--cpuset="0-2" or --cpuset="0,1,2": 绑定容器到指定CPU运行；-m :设置容器使用内存最大值；--net="bridge": 指定容器的网络连接类型，支持 bridge/host/none/container: 四种类型；--link=[]: 添加链接到另一个容器；--expose=[]: 开放一个端口或一组端口；--volume , -v: 绑定一个卷

这两种方法区别：

docker exec # 进入容器后开启一个新的终端，可以在里面操作*

docker attach # 进入容器正在执行的终端，不会启动新的进程

docker从容器中拷贝文件到主机

docker cp 容器id:容器内路径容器外路径

我们本地已经有了tomcat:9的镜像了，可以直接运行

docker run -d -p 3344:8080 --name tomcat01 tomcat:9  #后台运行tomcat，吧8080端口映射到3344端口，名称设置为tomcat01

docker: Error response from daemon: driver failed programming external connectivity on endpoint tomcat01 (d7acc0975879aa737958f8d12e7c58d144abe1a91ed23c4d65c2c10e6511ec29): Bind for 0.0.0.0:3344 failed: port is already allocated.

报错了，根据信息可以看得出，我们nginx的端口和tomcat设置的端口重复了，我们把nginx的容器关闭重新开启tomcat

root@ubuntu:/home/ubuntu# docker psCONTAINER ID   IMAGE     COMMAND                  CREATED         STATUS         PORTS                                   NAMES258ae4f6f9d8   nginx     "/docker-entrypoint.…"   6 minutes ago   Up 6 minutes   0.0.0.0:3344->80/tcp, :::3344->80/tcp   nginx01root@ubuntu:/home/ubuntu# docker stop 258ae4f6f9d8258ae4f6f9d8

刚刚运行的启动tomcat虽然报错，但是容器已经生成了；我们直接运行tomcat01容器就可以了

访问之后我们发现tomcat报错404

我们进入容器查看下可以发现webapps目录是空的，但是webapps.dist中有我们需要的文件

我们把webapps.dist中的文件复制到webapps目录中

刷新网站查看，成功进入tomcat

tomcat部署成功！

Dcoekr部署Mysql

我们的armv8架构需要不同的mysql（之前已经下载好了）

mysql oracle 3ffe8c471196 3 days ago 485MB

我们把我们刚刚修改好的tomcat9容器commit成了一个镜像，后面就可以直接使用这个镜像来创建容器而不用修改webapps文件夹了

容器数据卷

如果数据都在容器中，那么我们吧容器删除，容器中的数据就会丢失！

容器之间可以有一个数据共享技术！Docker容器中产生的数据，同步到本地！

这就是卷技术，目录的挂载，将我们容器内的目录挂载到linux目录上面！

**总结： **容器的持久化和同步操作！容器间数据也是可以共享的！

使用方法一：指定路径挂载 run -v来挂载

docker run -it -v /home/ceshi:/home centos /bin/bash     #centos镜像创建容器时吧/home目录挂载到主机/home/ceshi上

使用方法二：匿名挂载

docker run -it -v /home centos /bin/bash #会生成一个

docker volume ls     #查看所有volume卷的情况DRIVER              VOLUME NAMElocal               561b81a03506f31d45ada3f9fb7bd8d7c9b5e0f826c877221a17e45d4c80e096local               36083fb6ca083005094cbd49572a0bffeec6daadfbc5ce772909bb00be760882

这种情况就是匿名挂载

使用方法三：具名挂载

docker run -it  --name centos1 -v juming-centos:/etc centos

可以看到centos1容器的etc目录的所有数据

数据容器卷读写权限

# 通过 -v 容器内容路径 ro rw 改变读写权限ro  readonly    # 只读rw  readwrite   # 可读可写 docker run -d -P --name nginx02 -v juming-nginx:/etc/nginx:ro nginxdocker run -d -P --name nginx02 -v juming-nginx:/etc/nginx:rw nginx # ro 只要看到ro就说明这个路径只能通过宿主机来操作，容器内容无法操作

数据容器卷总结：

# 如何确定是具名挂载还是匿名挂载，还是指定路径挂载！-v  容器内路径                   # 匿名挂载-v  卷名:容器内路径               # 具名挂载-v /主机路径:容器内路径            # 指定路径挂载

DockerFile

DockerFile就是生成镜像的构建脚本，通过这个脚本可以生成镜像，镜像是一层一层的，脚本一个个的命令，每个命令都是一层。

# 我们这个文件的名字就是dockerfileFROM centos VOLUME ["volume01","volume02"] CMD echo "----end----"CMD /bin/bash

这个dockerfile中的意思就是从centos开始，匿名挂载了两个目录，cmd输出"----end----"并且使用bash打开这个自己构建的centos

构建dockerfile

docker build -f dockerfile -t baicha/centos1.0.1 .   #build构建了文件dockerfile，名称为baicha/centos,tag为1.0.1    ！！！一定不要忘记后面的点，代表当前路径下

可以看到数据已经互通了 此时我们如果启动了多个此镜像，数据会在多个容器中后互通

push镜像到官方平台

注册官方平台账号

在docker中使用login登陆

root@ubuntu:/home/ubuntu# docker login -u [用户名]Password: WARNING! Your password will be stored unencrypted in /root/.docker/config.json.Configure a credential helper to remove this warning. Seehttps://docs.docker.com/engine/reference/commandline/login/#credentials-storeLogin Succeeded

我们把刚构建好的baicha/centos镜像上传到官方库中

上传需要对我们需要上传的镜像重新打一个tag

可套用的公式其实是： docker tag 需要上传的镜像[:TAG] [docker hub自己注册的账号名]/镜像名[:TAG]

比如我的dockerhub账号是baicha123，存放的仓库为baicha-private。这时候我们就需要吧镜像名修改为baicha123/baicha-private：TAG

修改为域名/命名空间/仓库名:TAG #域名根据是什么网络，我是本地搭建的，就使用registry.cn-hangzhou.aliyuncs.com

push到阿里云仓库

root@ubuntu:/home/ubuntu# docker push registry.cn-hangzhou.aliyuncs.com/baicha/mycentos:1.0.1
The push refers to repository [registry.cn-hangzhou.aliyuncs.com/baicha/mycentos]
350f36b271de: Pushed
1.0.1: digest: sha256:61db0533f2c724e19a6120b64ec361a25cc6469a8a8cc2fc27bf19fbc796a803 size: 529

可以看到成功push上去了！

Docker网络、Docker Compose、Docker Swarm等技术点等博主忙完这一阵就更新！
