Install Docker on Ubuntu 22.04(LTS)

精选 原创

如果之前安装过旧版本Docker，需要先卸载。

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



卸载完成后，需要安装几个软件使得apt能够通过https安装软件。



sudo apt-get update

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



不过似乎都已经默认安装过了。



添加Docker的官方GPG密钥，好像是为了能够防止软件被篡改。



sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg



添加Docker软件源：



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



但是添加的源是国外的网站，根据经验来看速度必然很慢，因此刚才的代码应该改为：



echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null



安装Docker引擎等等：



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