Docker Basic

安装 docker

---

1. 二进制格式

   tar -xf /usr/local/src/docker/docker-19.03..tgz
   cd docker/
   mv * /usr/bin/
   mkdir /etc/docker
   vi /etc/docker/daemon.json
   dockerd &

2. yum 包

   yum install epel-release
   yum install docker-io

   centos-6

   yum install -y yum-utils
   yum-config-manager     --add-repo     https://download.docker.com/linux/centos/docker-ce.repo
   yum install docker-ce docker-ce-cli containerd.io
   systemctl status docker
   docker -v

   centos-7

   默认关闭了【nightly or test】在 docker-ce.repo 中：

   yum-config-manager --enable docker-ce-nightly
   yum-config-manager --enable docker-ce-test
   yum-config-manager --disable docker-ce-nightly
   yum-config-manager --disable docker-ce-test

   指定确定的版本来安装

   yum list docker-ce --showduplicates | sort -r
   yum install docker-ce-<VERSION_STRING> docker-ce-cli-<VERSION_STRING> containerd.io

3. 阿里安装

   # step : 安装必要的一些系统工具
   sudo yum install -y yum-utils device-mapper-persistent-data lvm2
   # Step : 添加软件源信息
   sudo yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
   # Step : 更新并安装Docker-CE
   sudo yum makecache fast
   sudo yum -y install docker-ce
   # Step : 开启Docker服务
   sudo service docker start
   
   # 注意：
   # 官方软件源默认启用了最新的软件，您可以通过编辑软件源的方式获取各个版本的软件包。例如官方并没有将测试版本的软件源置为可用，您可以通过以下方式开启。同理可以开启各种测试版本等。
   # vim /etc/yum.repos.d/docker-ee.repo
   #   将[docker-ce-test]下方的enabled=0修改为enabled=
   #
   # 安装指定版本的Docker-CE:
   # Step : 查找Docker-CE的版本:
   # yum list docker-ce.x86_64 --showduplicates | sort -r
   #   Loading mirror speeds from cached hostfile
   #   Loaded plugins: branch, fastestmirror, langpacks
   #   docker-ce.x86_64            17.03..ce-.el7.centos            docker-ce-stable
   #   docker-ce.x86_64            17.03..ce-.el7.centos            @docker-ce-stable
   #   docker-ce.x86_64            17.03..ce-.el7.centos            docker-ce-stable
   #   Available Packages
   # Step2: 安装指定版本的Docker-CE: (VERSION例如上面的17.03.0.ce.-.el7.centos)
   # sudo yum -y install docker-ce-[VERSION]

4. 服务管理

   systemctl start docker
   systemctl stop docker

   yum

5. 镜像加速

   {
     "registry-mirrors": ["http://hub-mirror.c.163.com","https://registry.docker-cn.com","https://mirror.ccs.tencentyun.com"]
   }

   daemon.json

   重新配置镜像信息，重启一下

   #这里操作，等同于登录到本地内建虚拟机执行编辑配置的操作
   docker-machine ssh default
   sudo vi /var/lib/boot2docker/profile
   # --registry-mirror http://hub-mirror.c.163.com
   exit
   docker-machine restart default
   # 检查添加
   docker info

   windows 环境下【DockerToolbox】

6. 卸载
   卸载 7 的 yum

   yum remove docker-ce docker-ce-cli containerd.io
   # $ du -sh  /var/lib/docker
   # .2G    /var/lib/docker
   rm -rf /var/lib/docker

镜像操作常用命令

---

1. 检索
   docker search 关键字
2. 拉取
   docker pull 镜像名称[:tag]
   tag 表示版本信息，默认是 latest
3. 本地镜像
   docker images
4. 删除本地镜像
   docker rmi IMAGE-ID

容器操作命令

---

• # 创建容器
  docker run -d [--name 容器名] 镜像名[:tag]
  #停止容器：
  docker stop [容器名|CONTAINER-ID]
  #启动容器：
  docker start [容器名|CONTAINER-ID]
  
  #查看容器
  #查看运行中的容器：
  docker ps
  #查看所有的现有容器：
  docker ps -a
  
  #删除容器
  docker rm [容器名|CONTAINER-ID]
  
  #端口映射
  docker run -d -p : [--name 容器名] [镜像名:tag]
  
  #查看容器日志
  docker logs [CONTAINER-ID|容器名]

  基本操作

  # 启动容器
  docker run -d --name myTomcat tomcat:
  
  # 启动容器并且映射端口到本地监听的 （默认tcp）
  docker run -d -p : --name myTomcat2 tomcat:

  启动一个 tomcat 容器

  #交互式启动容器
  docker run -it --name myCent centos:
  # ctro + p + q 退出容器保持运行，exit 退出并关闭容器

  交互式启动一个 linux 容器

• # 这是一个正在运行的 tomcat8
  $ docker inspect 39692a4836cd

  创建容器实例

• 容器数据卷

  #默认就是 rw
  docker run -it -v /data01:/data01 centos
  
  # ro
  docker run -it -v /data02:/data02:ro centos

  命令行方式创建

  $ cat mydocker/dockerfile
  FROM centos
  VOLUME ["/DATA01","/DATA02","/DATA03"]
  CMD echo "docker said that welcome argor."
  CMD /bin/bash
  
  $ docker build -f mydocker/dockerfile -t argor/centos: .
  
  $ docker images argor/centos

  $ docker run -it 67716c343a7b /bin/bash

  使用dockersfile创建一个新的镜像

• 数据卷容器

  docker run -it --name wonderful_swirles argor/demo
  docker run -it --name again --volumes-from wonderful_swirles argor/demo

  volumes-from

Docker .
