前言：
Docker 核心概念
Docker 镜像操作
Docker 容器操作
Docker 资源控制
Docker 数据卷管理
一：Docker概述
官方网站：www.docker.com
官方文档：docs.docker.com
docker是一种轻量级的”虚拟机“
在linux容器里运行的开源工具
容器内的应用程序之间相互隔离、互不影响
便于应用拆分、解耦
例：LNMP——部署到同一台主机中
linux ——容器1
nginx——容器2
mysql——容器3
php-fpm——容器4
应用之间不受影响，可以方便迁移
1.1 docker概念：
daocker是一个开源的应用容器引擎（相当于vm 15就是虚拟机的引擎），让开发者可以打包他们的应用以及依赖包到一个可移植的镜像中；然后发布到任何流行的linux或windows机器上，也可以实现虚拟化
容器是完全使用沙箱机制，相互之间不会有任何接口
docker不需要虚拟出来硬件，比如虚拟cpu、虚拟磁盘；docker是进程之间的隔离
1.2 docker设计的目标：
提供简单的应用程序打包工具
开发人员和运维人员职责逻辑分离
多环境保持一致性
1.3 docker的组成：
- docker Client ——客户端
- docker Daemon——守护进程
- docker Images——镜像
- docker container ——容器
- docker registry ——镜像仓库
输入的指令交由客户端，客户端转发给守护进程处理
守护进程识别处理命令，比如说制造镜像images；也可以从仓库(regisstry，分为公有和私有)中拉取，从这中间需要一个加速器,后面去配置一个阿里云加速器
利用镜像images，直接制造容器containors
容器会开放端口，用以客户访问
彼此进程之间是相互隔离的，采用的就是解耦的思想
docker可以在秒级别的层面去扩展收缩节点
容器内的应用可以直接打包成镜像上传到仓库内
1.4 docker的使用场景
打包应用程序简化部署——做镜像文件
可脱离底层硬件任意迁移
例：服务器从腾讯云迁移到阿里云
应用程序打包和发布
应用程序隔离
持续集成
部署微服务
快速搭建测试环境
提供paas（平台即服务）
1.5 docker版本：
社区版（community edition，CE）
企业版（Enterprise edition，EE） 增值服务
二： docker与虚拟机的区别
openstack的云主机搭建是基于IAAS基础设施即服务的层面搭建
docker（k8s）的容器containors是基于PAAS平台即服务的层面搭建
区别于VMware Workstation Pro、kvm、exsi、hyper-v 微软、Virtual box的硬件虚拟化，docker是基于进程的隔离
app 应用
bins/libs 进程
guest OS 安装虚拟机系统（guest OS）
docker engine/安装虚拟化引擎 hypervisor/监控平台
openrating system 宿主系统
infrastructure 硬件层面
备注：
-
docker 没有虚拟系统层面
-
hypervisor会侵占5%的cpu资源
-
docker engine 几乎忽略，只损耗关于网络通信的资源
-
docker的安全性低，因为是在宿主系统直接安装
-
虚拟机因为有一个虚拟机系统，所以安全性要高
备注：
-
磁盘占用，docker占用空间少，因为他是个进程级别
-
docker主要支持linux
docker支持平台
- linux（centos、debian、fedora、oracle linux、rhel、suse、ubuntu）
- mac
- windows
二：docker的核心概念及安装方式
镜像
容器
仓库
2.1 centos安装docker的两种方式
- 使用curl 获得docker的安装脚本进行安装
- 使用yum仓库来安装docker
2.2 实操演示
2.2.1 关闭防火墙，核心防护
[root@nginx ~]# systtemctl stop firewalld
-bash: systtemctl: command not found
[root@nginx ~]# systemctl stop firewalld
[root@nginx ~]# systemctl disable firewalld
[root@nginx ~]# setenforce 0
setenforce: SELinux is disabled
[root@nginx ~]# sed -i 's/^SELINUX=.*/SELINUX=disabled/' /etc/selinux/config

2.2.2 部署19版docker
- 安装依赖包
[root@nginx ~]# yum install -y yum-utils device-mapper-persistent-data lvm2
- 1
- 设置阿里云镜像源
[root@nginx ~]# cd /etc/yum.repos.d/
[root@nginx yum.repos.d]# yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
Loaded plugins: fastestmirror
adding repo from: https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
grabbing file https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo to /etc/yum.repos.d/docker-ce.repo
repo saved to /etc/yum.repos.d/docker-ce.repo
[root@nginx yum.repos.d]# ls
docker-ce.repo //新增

- 开启docker服务，并开启自启
[root@nginx yum.repos.d]# systemctl start docker
[root@nginx yum.repos.d]# systemctl enable docker
- 1

2.2.3 使用阿里云设置镜像加速器
打开https://help.aliyun.com/document_detail/60750.html
登录，点击容器镜像服务控制台
前往开通
设置密码
tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://fk2yrsh1.mirror.aliyuncs.com"]
}
EOF

[root@nginx ~]# docker ps -a

[root@nginx ~]# cat nginx_c | docker import - nginx:c
