一、什么是 Docker
Docker 是一个开源的容器化平台,可以使开发者将应用及其依靠打包到一个容器中,而且可以在任何情况中一致地运行。容器是轻量级的、可移植的,可以实现跨平台和跨情况的部署。
Docker 与虚拟化的区别
虚拟化
:虚拟机需要虚拟化硬件,启动时占用大量资源,启动时间较长。
容器化
:容器通过共享操纵体系内核来创建多个隔离的运行情况,资源占用少,启动敏捷。
二、Docker 安装与卸载
1. Docker 安装

[root@docker:~]# ll autoinstall-docker-docker-compose.tar.gz
-rw-r--r-- 1 root root 84288398 Feb 27 19:04 autoinstall-docker-docker-compose.tar.gz
[root@docker:~]# ./install-docker.sh i
[root@docker:~]# docker --version
Docker version 20.10.24, build 297e128
复制代码
验证安装是否成功,通过运行 hello-world 镜像
[root@docker:~]# docker run crpi-z431eabbod8b9a37.cn-shenzhen.personal.cr.aliyuncs.com/jasper2024/k8s: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:

2. Docker 卸载
[root@docker:~]# ./install-docker.sh r
Removed /etc/systemd/system/multi-user.target.wants/docker.service.
Docker 卸载成功!
