在 Ubuntu 22.04 LTS 中安装 Docker

1.更新 Ubuntu apt update

2.添加 Docker 库
首先，安装必要的证书并允许 apt 包管理器使用以下命令通过 HTTPS 使用存储库：

sudo apt install apt-transport-https ca-certificates curl software-properties-common gnupg lsb-release

然后，运行下列命令添加 Docker 的官方 GPG 密钥：

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

添加 Docker 官方库：

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

使用命令更新 Ubuntu 源列表：

sudo apt update

安装 Docker

最后，运行下列命令在 Ubuntu 22.04 LTS 服务器中安装最新 Docker CE：

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

sudo systemctl start docker
sudo systemctl enable docker

一键安装命令

sudo apt install -y apt-transport-https ca-certificates curl software-properties-common gnupg lsb-release
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
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
sudo apt update -y
sudo apt install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin
sudo systemctl start docker
sudo systemctl enable docker

sudo usermod -aG docker $USER
newgrp docker
