你好呀，我的老朋友！我是老寇，欢迎来到老寇IoT云平台！

查看系统版本及架构

lsb_release -a
dpkg --print-architecture

安装 Docker【Amd64 Ubuntu 22.04】

注意：需要检查是否安装SSH，否则无法连接主机

# 安装
sudo apt-get install openssh-server
# 查看状态
sudo systemctl status ssh
# 启动
sudo systemctl start ssh
# 开机启动
sudo systemctl enable ssh

1.更新包索引

sudo apt-get update

2.安装必要的系统工具

sudo apt-get install apt-transport-https ca-certificates curl software-properties-common

3.添加 Docker 官方 GPG 密钥【没添加好就多试几次】

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

4.添加 Docker 仓库

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

5.再次更新包索引

sudo apt-get update

6.安装 Docker CE

sudo apt-get install docker-ce

7.启动 Docker 服务

## 启动
sudo systemctl start docker
# 查看状态
sudo systemctl status docker
# 开机启动
sudo systemctl enable docker

8.安装Docker Compose

sudo wget https://github.com/docker/compose/releases/download/v2.40.3/docker-compose-linux-x86_64
mv docker-compose-linux-x86_64 /usr/local/docker-compose
sudo chmod +x /usr/local/docker-compose
# 全局设置
sudo ln -s /usr/local/docker-compose /usr/bin/docker-compose
# 查看版本
docker-compose --version

9.远程访问

sudo apt-get install vim
sudo vim /usr/lib/systemd/system/docker.service
# 找到 ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock 这行，添加 -H tcp://0.0.0.0:2375
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H fd:// --containerd=/run/containerd/containerd.sock

sudo systemctl daemon-reload
sudo systemctl restart docker

安装 Docker【Arm64 Ubuntu20.04】

1.卸载旧版本（避免冲突）

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

2.安装依赖

sudo apt-get update
sudo apt-get install -y ca-certificates curl gnupg lsb-release

3.添加 Docker 官方 GPG key

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

4.添加官方仓库

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

5.更新包索引

sudo apt-get update

6.安装 Docker CE

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

我是老寇，我们下次再见啦！
