前言
Docker 是一个开源的应用容器引擎，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 操作系统的机器上，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 入门
Docker 为什么会出现
在 Docker 之前，一款产品需要两种配置环境（开发环境和运维上线环境）。
由于
开发和运维的环境（电脑操作系统、软件版本等）不同，经常导致运维人员无法成功部署产品。分布式系统（如
Hadoop）需要为每一个电脑配置环境，非常麻烦。由于开发人员经常使用
Windows或者MacOS进行开发，然后将产品部署到Linux上，因此经常出现无法成功部署问题。
Docker 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 操作系统的机器上，进而解决了上面问题。
Docker 的思想来自于集装箱！隔离机制（容器是完全使用沙箱机制，相互之间不会有任何接口。）使得 Docker 能够轻松的部署软件，并且各个软件不会相互冲突。
Docker 通过隔离机制，使得服务器可以被利用到极致。
Docker 的历史
Docker 是 PaaS 提供商 dotCloud 开源的一个基于 LXC 的高级容器引擎，源代码托管在 Github 上, 基于 go 语言并遵从 Apache2.0 协议开源。
与 Docker （容器技术）相对应是虚拟机技术（如 VMware）。
虚拟机技术: 在本地操作系统（如Windows）装一个VMware，通过VMware可以虚拟出来一个新的电脑（操作系统）。相当笨重！虚拟机技术和Docker（容器技术）都属于虚拟化技术！
VMware:Linux centos原生镜像相当于一台完整的电脑，每个都需要几个G，每次启动都需要几分钟。
docker: 镜像一般十分小巧，只有几M或者几KB，秒级启动。
Docker 是基于 Go 语言开发的！是一个开源项目。
Docker 的官网地址为：https://www.docker.com/ 。
Docker 的官方文档地址为：https://docs.docker.com/ 。
Docker Hub 的地址为：https://hub.docker.com/ 。
虚拟机技术和容器化技术对比
虚拟机技术的缺点
如下图，每一个虚拟机都包括操作系统内核、库文件和上层应用软件。
资源占用十分多。冗余步骤多。启动很慢。
容器化技术
Docker 和虚拟机技术的区别：
传统虚拟机会首先虚拟出一个完整的操作系统和相关硬件，然后在这个系统上安装和运行软件。Docker的容器是没有自己的内核的，也没有相关硬件。容器内的应用是直接运行在宿主机上的，因此十分的轻巧。容器间是相互隔离的，每个容器都有一个独立的文件系统，因此各个容器互不影响。
DevOps(开发和运营维护)
更快速的交互和部署
传统开发和运营维护：大量帮助文档和安装程序。Docker: 打包镜像，一键运行。
更便捷的升级和扩缩容
Docker会像搭积木一样部署应用。整个项目会被打包成一个镜像。
更简单的系统运维
- 开发和测试环境高度一致。
更高效的计算机资源利用
Docker是内核级别的虚拟化，可以在一个物理机上运行多个容器实例！服务器的性能可以被压榨到极致。
名词解释
镜像（image）
Docker镜像相当于模板，可以用于创建Docker容器服务。一个镜像可以创建多个Docker容器服务（我们软件或者服务是运行在容器中的）。
容器（container）
Docker通过镜像来创建一个或者多个容器，进而独立运行一个或者一组应用。容器具有启动、停止和删除等基本命令！
可以把容器理解为一个独立的
linux系统。
仓库（repository）
- 存放镜像的地方。如
Docker Hub和阿里云镜像服务器。
- 存放镜像的地方。如
安装 docker
官方 Ubuntu 安装 Docker Engine 教程为：Install Docker Engine on Ubuntu。
为了在 Ubuntu 安装 Docker Engine，确保你满足 prerequisites，然后安装 Docker。
Prerequisites
OS requirements
为了安装 Docker Engine，你需要这些 Ubuntu 版本之一的 64 位版本：
Ubuntu Jammy 22.04 (LTS)
Ubuntu Impish 21.10
Ubuntu Focal 20.04 (LTS)
Ubuntu Bionic 18.04 (LTS)
Docker Engine 支持 x86_64 (or amd64)，armhf，arm64，和 s390x 体系结构。
通过下面命令获得本机体系结构：
$ hostnamectlUninstall old versions
旧版本的 Docker 被称为 docker，docker.io 或 docker-engine。如果安装了这些，请卸载它们：
$ sudo apt-get remove docker docker-engine docker.io containerd runcIt’s OK if
apt-getreports that none of these packages are installed.The contents of
/var/lib/docker/, includingimages,containers,volumes, andnetworks, are preserved. If you do not need to save your existing data, and want to start witha clean installation, refer to theuninstall Docker Enginesection.
Installation methods
You can install Docker Engine in different ways, depending on your needs:
Most users
set up Docker’s repositoriesand install from them, for ease of installation and upgrade tasks. This is the recommended approach.Some users download the DEB package and
install it manuallyand manage upgrades completely manually. This is useful in situations such as installing Docker on air-gapped systems with no access to the internet.In testing and development environments, some users choose to use automated
convenience scriptsto install Docker.
Install using the repository
Before you install Docker Engine for the first time on a new host machine, you need to set up the Docker repository. Afterward, you can install and update Docker from the repository.
Set up the repository
- Update the
aptpackage index andinstall packagesto allowaptto use a repository over HTTPS:
$ sudo apt-get update
$ sudo apt-get install \
ca-certificates \
curl \
gnupg \
lsb-release- Add Docker’s official GPG key:
$ sudo mkdir -p /etc/apt/keyrings
$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg- Use the following command to set up the repository:
$ echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/nullInstall Docker Engine
- Update the
aptpackage index, and install thelatest versionofDocker Engine,containerd, andDocker Compose:
$ sudo apt-get update
# 下面的安装命令第一次可能出错，需要再次运行一次
$ sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin
$ sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin- Verify that Docker Engine is installed correctly by running the
hello-worldimage.

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.

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.

}底层原理
Docker Engine 是一个客户端-服务器应用程序，具有以下主要组件：
一个
服务器，是一个长期运行的程序，被称为守护进程。一个
REST API，该API可以指定某些程序（如bash）与守护进程交互，进而向守护进程发出指令。
Docker 是一个 Client Server 结构的系统。Docker 守护进程运行在宿主机上，客户端可以通过 Socket 访问守护进程，进而管理运行在宿主机上的容器（一个运行时环境）。
为什么 Docker 比 VMware 快
docker有着比虚拟机更少的抽象层，docker不需要Hypervisor实现硬件虚拟化，docker容器上的程序直接使用宿主机上的硬件资源。因此，docker更能充分利用宿主机上的CPU、内存等资源。docker利用的是宿主机的内核，不需要Guest OS。因此，当新建一个容器时，docker不需要和虚拟机一样重新加载一个操作系统内核，因而只需几秒钟；虚拟机需要加载Guest OS，需要几分钟。

Docker 安装 Tomcat
docker hub 中 tomcat 的主页：https://hub.docker.com/_/tomcat 。
# 官方的使用
# 我们之前的启动都是后台的，停止了容器之后，容器还是可以查到
# --rm 一般用来测试，用完就删
$ docker run -it --rm tomcat:9.0
# 下载
$ docker pull tomcat
# 启动运行
$ docker run -d -p 3344:8080 --name tomcat01 tomcat
# 测试访问没有问题
# 进入容器
$ docker exec -it tomcat01 /bin/bash
# 发现的问题：
# 该镜像默认是最小的镜像，所有不必要的都删除了，保证最小可运行环境即可
# 1. linux 命令较少
# 2. webapps 下内容为空(base) lyfubuntu@lyfubuntu:~/my_computer_language/docker$ docker run --help

Docker 部署 elasticsearch
docker hub 中 elasticsearch 的主页：https://hub.docker.com/_/elasticsearch 。
官方使用方法
How to use this image
Note: Pulling an images requires using a specific version number tag. The latest tag is not supported.
For Elasticsearch versions prior to 6.4.0 a full list of images, tags, and documentation can be found at docker.elastic.co.
For full Elasticsearch documentation see here.
The commands below are intended for deploying in a development context only. For production installation and configuration, see Install Elasticsearch with Docker.
Running in Development Mode
Create user defined network (useful for connecting to other services attached to the same network (e.g. Kibana)):
$ docker network create somenetworkRun Elasticsearch:
$ docker run -d --name elasticsearch --net somenetwork -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:tagRunning in Production Mode
See Install Elasticsearch with Docker
# es 暴露的端口很多
# es 十分的耗内存
# es 的数据一般需要放置到安全目录！ 挂载
# --net somenetwork 网络配置
# 启动 elasticsearch
$ docker run -d --name elasticsearch --net somenetwork -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:7.6.2
$ docker run -d --name elasticsearch -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:7.6.2

Docker 原理
Docker 镜像都是只读的，当容器启动时，一个新的可写层被加载到镜像的顶部！这一层就是我们通常说的容器层，容器层之下的都叫做镜像层。
commit 镜像
# 提交容器成为一个新的镜像
docker commit
# 命令和 git 原理类似
docker commit -m="提交的描述信息" -a="作者" 容器id 目标镜像名:[TAG]
docker commit -a="xiaofan" -m="add webapps app" d798a5946c1f tomcat007:1.0实战测试
# 1. 启动一个默认的 tomcat
# 2. 发现这个默认的 tomcat 没有 webapps 应用，镜像的原因，官方镜像默认 webapps 下面是没有内容的
# 3. 我自己拷贝进去了基本的文件
# 4. 将我们操作过的容器通过 commit 提交为一个镜像！我们以后就使用我们自己制作的镜像了(base) lyfubuntu@lyfubuntu:~/my_computer_language/docker$ docker commit --help

(base) lyfubuntu@lyfubuntu:~/my_computer_language/docker/my_centos$docker 的回顾
问题: 如果将应用和环境打包成一个镜像，那么容器被删除，容器中的数据就会丢失！
需求: 数据需要持久化。
MySQL: 容器删了 == 删库跑路，需求: MySQL 数据需要存储到本地！
容器数据卷: 数据共享技术，Docker 容器中产生的数据会同步到本地。
容器数据卷: 就是目录挂载 -> 将容器内目录挂载到宿主机目录上面！
总结: 容器数据卷 -> 数据持久化、同步( 宿主机和容器 )和共享( 容器间 )。
数据卷
使用
docker run -v挂载目录
docker run -it -v 主机目录:容器目录

容器之间的配置信息可以通过数据卷容器传递。数据卷容器的生命周期一直持续到没有容器使用为止。一旦你持久化到了
本地，这个时候，本地的数据是不会删除的！
Dockerfile
dockerFile 是用来构建 docker 镜像的文件！命令参数脚本！
构建步骤
编写一个
dockerFile文件。docker build使用dockerFile构建一个镜像。docker run运行镜像。docker push发布镜像（DockerHub、阿里云镜像）。
很多官方镜像都是基础包，很多功能都不具备，我们通常会自己搭建镜像！
官方既然可以制作镜像，我们一样可以！
Dockerfile 的构建过程
基础知识:
每个
保留关键字（指令）都必须是大写字母。从上到下顺序执行。#表示注释。每个
指令都会创建一个新的镜像层。
Dockerfile是面向开发的，我们以后要发布项目->镜像-> 编写Dockerfile文件。
Docker镜像逐渐成为企业的交付标准，必须要掌握！
步骤：开发、部署、运维… 缺一不可！
Dockerfile: 构建文件，定义了一切的步骤（源代码）。
DockerImages: 通过Dockerfile构建生成的镜像，最终发布的产品！
DockerContainer: 容器就是镜像运行起来创建的服务器。
Dockerfile 指令说明
FROM # 基础镜像，一切从这里开始构建
MAINTAINER # 镜像的作者，姓名+邮箱
RUN # 镜像构建的时候需要运行的命令
ADD # COPY 文件，会自动解压
WORKDIR # 镜像的工作目录
VOLUME # 挂载的目录
EXPOSE # 暴露的端口
CMD # 指定这个容器启动的时候要运行的命令，只有最后一个会生效，可以被替代
ENTRYPOINT # 指定这个容器启动的时候要运行的命令，可以追加命令
ONBUILD # 该 dockerfile 文件创建的镜像被当做基础镜像创建一个新镜像时，会运行 ONBUILD 的指令，是一个触发指令
COPY # 将文件拷贝到镜像中
ENV # 设置环境变量！创建一个自己的 centos
# 1. 编写 Dockerfile
$ cat mydockerfile-centos
FROM centos
MAINTAINER xiaofan<594042358@qq.com>
ENV MYPATH /usr/local
WORKDIR $MYPATH # 镜像的工作目录
RUN yum -y install vim
RUN yum -y install net-tools
EXPOSE 80
CMD echo $MYPATH
CMD echo "---end---"
CMD /bin/bash
# 2. 通过这个文件构建镜像
# 命令 docker build -f dockerfile文件路径 -t 镜像名:[tag] .
$ docker build -f mydockerfile-centos -t mycentos:0.1 .
Successfully built d2d9f0ea8cb2
Successfully tagged mycentos:0.1
我们可以列出本地进行的变更历史。

(base) lyfubuntu@lyfubuntu:~/my_computer_language/docker/tomcat_ip_ping$结论: 容器与容器之间是可以相互 ping 通的！
绘制一个网络模型图
结论: tomcat01 和 tomcat02 共用一个路由器: docker0。
所有容器在不指定网络的情况下，都是使用 docker0 路由的。docker 会给我们的容器分配一个默认的可用 IP 地址。
docker 使用的是 linux 的桥接，宿主机有一个 docker 容器的网桥 docker0。
docker 中所有的网络接口都是虚拟的，虚拟的转化效率高！( 内网传递文件 )
只要容器删除，对应的网桥也被删除。
