1 - 安装概述
Docker 目前分为 Community Edition (CE) 和 Enterprise Edition (EE) 两个版本。日常学习开发考虑使用CE版本。
而 Docker Community Edition (CE) 又分为 Stable / Test / Nightly 三个版本,如果不需要最新的特性,那么 Stable 是比较合适的选择。
以下安装都是选择 Docker Community Edition Stable 版本, 参考docker官网的文章:
2 - Ubuntu下安装Docker
参考官网文档:
https://docs.docker.com/install/linux/docker-ce/ubuntu/
适用于以下版本:
- Ubuntu Lunar 23.04
- Ubuntu Kinetic 22.10
- Ubuntu Jammy 22.04 (LTS)
- Ubuntu Focal 20.04 (LTS)
准备工作
清除老版本:
for pkg in docker.io docker-doc docker-compose podman-docker containerd runc; do sudo apt-get remove $pkg; done
安装需要的工具:
sudo apt-get update
sudo apt-get install ca-certificates curl gnupg
添加 GPG key:
sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg
准备用于 apt 的仓库:
echo \
"deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
"$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
此时打开 /etc/apt/sources.list.d/docker.list
文件:
sudo vi /etc/apt/sources.list.d/docker.list
就能看到如下内容:
deb [arch=amd64 signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu jammy stable
其中 jammy
是ubuntu版本代码名称 VERSION_CODENAME ,其内容来自文件 /etc/os-release
:
PRETTY_NAME="Ubuntu 22.04.2 LTS"
NAME="Ubuntu"
VERSION_ID="22.04"
VERSION="22.04.2 LTS (Jammy Jellyfish)"
VERSION_CODENAME=jammy
ID=ubuntu
ID_LIKE=debian
HOME_URL="https://www.ubuntu.com/"
SUPPORT_URL="https://help.ubuntu.com/"
BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/"
PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy"
UBUNTU_CODENAME=jammy
注意
对于 Linux Mint 这样的基于 ubuntu 的发行版本,VERSION_CODENAME 会不一样。
因此需要在安装 docker 时,需要修订这个值为对应 ubuntu 的值,或者叫做 UBUNTU_CODENAME
ubuntu各个版本的codename 请见:https://download.docker.com/linux/ubuntu/dists/
执行 apt update 之后:
sudo apt-get update
就可以安装了。
安装
一般 不推荐 安装最新版本,尤其是和 k8s 一起使用时:
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
可以先执行
apt-cache madison docker-ce
# apt-cache madison docker-ce | awk '{ print $3 }'
查看当前可选版本:

docker-ce | 5:20.10.13~3-0~ubuntu-jammy | https://download.docker.com/linux/ubuntu jammy/stable amd64 Packages
这里先固定使用 20.10.21 版本, 执行安装命令:
VERSION_STRING=5:20.10.21~3-0~ubuntu-jammy
sudo apt-get install docker-ce=$VERSION_STRING docker-ce-cli=$VERSION_STRING containerd.io docker-buildx-plugin docker-compose-plugin
安装完成后检验一下:
sudo docker run hello-world
查看安装的版本:
$ docker --version
Docker version 20.10.21, build baeda1f
设置
设置权限避免每次sudo
为了以非 root 用户使用 docker, 可以将用户加入 “docker” 组.
sudo usermod -aG docker sky
重新登录之后生效。验证一下:
docker run hello-world
取消 apt source 更新
docker 安装之后,没有必要时刻保持更新,因此可以取消 apt source的设置,加速 apt update 的执行:
sudo vi /etc/apt/sources.list.d/docker.list
将内容注释即可。
修改 containerd 的配置
containerd 的默认配置文件中 disable 了 CRI ,可以打开文件 /etc/containerd/config.toml
看到这行:
disabled_plugins = ["cri"]
将这行注释之后,重启 containerd:
sudo systemctl restart containerd.service
如果不做这个修改,k8s 安装时会报错 “CRI v1 runtime API is not implemented”。
3 - Macos下安装Docker
参考:
下载
- Mac with Intel chip: intel 芯片
- Mac with Apple silicon):m1 芯片
m1安装
对于 m1 芯片的用户,先安装 rosetta 2:
softwareupdate –install-rosetta
正常安装,过程简单。
验证一下安装,看一下版本信息:
$ docker version

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.
(arm64v8)
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

intel芯片安装
TBD:准备放弃黑苹果,专心用m1。
4 - Docker安装后的设置
镜像加速
为了加速拉取 Docker ,需要配置镜像地址:
- 网易的镜像地址:http://hub-mirror.c.163.com
- 或者用阿里云的镜像: 打开地址 https://cr.console.aliyun.com/cn-hangzhou/mirrors 查看专属加速器地址,一般是 https://****.mirror.aliyuncs.com
mac下修改
任务栏点击 Docker for mac 应用图标 -> Perferences… -> Daemon -> Registry mirrors。
linux下修改
针对Docker客户端版本大于 1.10.0 的用户
通过修改daemon配置文件/etc/docker/daemon.json来使用加速器
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://****.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

5 - [归档]ubuntu 16.04下安装Docker
归档原因:不再使用ubuntu 16.04.
以 ubuntu 为例,参考官网文档:
https://docs.docker.com/install/linux/docker-ce/ubuntu/
安装准备
看一下自己的Linux机器版本和内核信息:
-

lsb_release -a
No LSB modules are available. Distributor ID: LinuxMint Description: Linux Mint 18.3 Sylvia Release: 18.3 Codename: sylvia
这台机器是Linux Mint 18.3 升级到非常新的Linux内核4.15.0-38了,Linux Mint 18.3 是基于 Ubuntu 16.04,但是有些系统参数不一样,比如这里 Codename 是 sylvia
,而不是 Ubuntu 16.04 的 xenial
。后面安装时要小心,需要修改为 Ubuntu 16.04 的参数。
安装步骤
-
卸载旧版本
sudo apt-get remove docker docker-engine docker.io
-
安装docker
简单起见,使用 docker 仓库安装。
sudo apt-get install apt-transport-https ca-certificates curl software-properties-common curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add - # 官方给的是这样,但是`lsb_release -cs`在Linux Mint下取值会不对,因此手工修改 # Linux Mint 18是基于ubuntu 16.04,为 xenial # Linux Mint 19是基于ubuntu 18.04,为 bionic # sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" # for ubuntu 16.04 / linuxmint 18.* sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu xenial stable" # for ubuntu 18.04 / linuxmint 19.* sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable" sudo apt-get update sudo apt-get install docker-ce

Hello from Docker!

设置权限避免每次sudo
为了以非root用户使用docker, 可以将用户加入"docker"组.
sudo usermod -aG docker sky
重新登录之后生效。
设置docker的cgroup driver
备注: 发现 docker 20.10.21~3-0~ubuntu 版本已经修改为默认 systemd ,因此新版本可以不用这么设置。
docker 默认的 cgroup driver 是 cgroupfs,可以通过 docker info 命令查看:
$ docker info | grep "Cgroup Driver"
Cgroup Driver: cgroupfs
而 kubernetes 在v1.22版本之后,如果用户没有在 KubeletConfiguration 下设置 cgroupDriver 字段,则 kubeadm 将默认为 systemd
。
为了保持一致,需要修改 docker 的 cgroup driver 为 systemd
, 方式为打开 docker 的配置文件(如果不存在则创建)
sudo vi /etc/docker/daemon.json
增加内容:
{
"exec-opts": ["native.cgroupdriver=systemd"]
}
修改完成后重启 docker:
sudo systemctl restart docker
# 重启后检查一下
docker info | grep "Cgroup Driver"
设置swap limit
如果遇到如下的 “No swap limit support” 警告:
docker info | grep "Cgroup Driver"
Cgroup Driver: systemd
WARNING: No swap limit support
则说明 swap limit 功能没能开启。解决方法是 grub
$ sudo vi /etc/default/grub
......
GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount=1"
......
注意
如果 GRUB_CMDLINE_LINUX= 内有内容,切记不可删除,只需在后面追加,并用空格和前面的内容分隔开。执行下面命令生效并重启。
$ sudo update-grub2
$ sudo reboot
