安装 Docker Engine

Ubuntu 安装

1. 通过仓库安装

1.1. 移除旧版本

sudo apt-get remove docker docker-engine docker.io containerd runc

支持的存储驱动
overlay2(默认), aufs , btrfs

1.2 配置仓库

sudo apt-get update

sudo apt-get install \
    ca-certificates \
    curl \
    gnupg \
    lsb-release

1.3. 添加 GPG key

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

1.4. 配置稳定版仓库

echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

1.5. 安装 Docker Engine

sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io

结果:

public@public:~$ sudo apt-get install docker-ce docker-ce-cli containerd.io

安装指定版本的 Docker

列举仓库中可用的 Docker 版本

apt-cache madison docker-ce

结果如下:

 docker-ce | 5:20.10.13~3-0~ubuntu-bionic | https://download.docker.com/linux/ubuntu bionic/stable amd64 Packages
 docker-ce | 5:20.10.12~3-0~ubuntu-bionic | https://download.docker.com/linux/ubuntu bionic/stable amd64 Packages
 docker-ce | 5:20.10.11~3-0~ubuntu-bionic | https://download.docker.com/linux/ubuntu bionic/stable amd64 Packages
 ....

安装指定版本的 docker
比如,我安装 5:20.10.13_3-0ubuntu-bionic

sudo apt-get install docker-ce=5:20.10.13~3-0~ubuntu-bionic docker-ce-cli=5:20.10.13~3-0~ubuntu-bionic containerd.io

1.5 验证

命令:

 sudo docker run hello-world

控制台输出:

Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
2db29710123e: Pull complete 
Digest: sha256:f861ba8563637d693e3043069b0a4ebf3d92c2e865b541379f6a6b8164b7c8bb
Status: Downloaded newer image for hello-world: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

2. 通过安装包安装

2.1. 下载安装包

访问 https://download.docker.com/linux/ubuntu/dists/, 选择自己的操作系统版本,我的是 18.04 对应是bionic;
然后访问 https://download.docker.com/linux/ubuntu/dists/bionic/pool/stable/amd64/ 下载对应的 .deb 文件.

有以下几类文件:
containerd.io_1.5.10-1_amd64.deb
docker-ce-cli_20.10.9_3-0ubuntu-bionic_amd64.deb
docker-ce-rootless-extras_20.10.9_3-0ubuntu-bionic_amd64.deb
docker-ce_20.10.9_3-0ubuntu-bionic_amd64.deb
docker-compose-plugin_2.3.3~ubuntu-bionic_amd64.deb
docker-scan-plugin_0.17.0~ubuntu-bionic_amd64.deb

2.2. 安装安装包

sudo dpkg -i 下载好的deb文件

2.3. 验证

sudo docker run hello-world

如何卸载 Docker ?

卸载 docker-ce docker-ce-cli containerd.io
命令:

sudo apt-get purge docker-ce docker-ce-cli containerd.io

删除所有的容器,镜像和卷

 sudo rm -rf /var/lib/docker
 sudo rm -rf /var/lib/containerd
