Ubuntu 22.04安裝docker

如果之前有安裝過舊版本，則通過此命令刪除舊版本

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

# 更新資源庫
$ sudo apt-get update
# 安裝證書
$ sudo apt-get install \
    ca-certificates \
    curl \
    gnupg \
    lsb-release
# 安裝官方GPG key
$ sudo mkdir -p /etc/apt/keyrings
################  這段可以替換為國內(nèi)阿里云鏡像地址 開始
### 將2塊 `https://download.docker.com/linux/ubuntu` 替換為 `https://mirrors.aliyun.com/docker-ce/linux/ubuntu`
$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
# 建立docker資源庫
$ 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/null

# 再次更新資源庫
$ sudo apt-get update
# 開始安裝
$ sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin
# 驗(yàn)證 是否安裝成功
$ sudo docker -v

Windows 10 子系統(tǒng)Ubuntu 22.04 按以上步驟安裝完docker后，啟動(dòng) docker 可能會(huì)報(bào)錯(cuò)

$ docker ps
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
$ sudo service docker start

$ cat /var/log/docker.log

以上可以通過將 iptables 切回 iptables-legacy文章來源地址http://www.zghlxwxcb.cn/news/detail-630872.html

$ sudo update-alternatives --config iptables
There are 2 choices for the alternative iptables (providing /usr/sbin/iptables).

  Selection    Path                       Priority   Status
------------------------------------------------------------
* 0            /usr/sbin/iptables-nft      20        auto mode
  1            /usr/sbin/iptables-legacy   10        manual mode
  2            /usr/sbin/iptables-nft      20        manual mode

Press <enter> to keep the current choice[*], or type selection number: 1
update-alternatives: using /usr/sbin/iptables-legacy to provide /usr/sbin/iptables (iptables) in manual mode

$ sudo service docker start
 * Starting Docker: docker                                                                                       [ OK ]
$ docker ps -a
