Ubuntu上安装Docker及可视化管理工具的流程步骤

#更新软件包索引
sudo apt update
 
#安装添加 Docker 仓库所需的前置软件包
sudo apt install apt-transport-https curl

#阿里云镜像源
curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
 
#官方网站
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

#添加Docker的阿里云仓库到软件源列表
echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://mirrors.aliyun.com/docker-ce/linux/ubuntu/ $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
 
#添加Docker的官方仓库到软件源列表
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

#刷新软件包列表，以便系统识别新添加的 Docker 仓库
sudo apt update

#安装Docker 引擎及其相关组件
sudo apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin docker-ce-rootless-extras

#检查 Docker 的运行状态
sudo systemctl is-active docker

#运行 hello-world 测试容器，验证 Docker 是否安装成功并正常工作
sudo docker run hello-world

sudo vim /etc/docker/daemon.json

{
  "registry-mirrors": [
    "https://docker.1ms.run",
    "https://dockerpull.org"
  ]
}

sudo systemctl daemon-reload
sudo systemctl restart docker

sudo docker info

sudo apt purge docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin docker-ce-rootless-extras

sudo rm -rf /var/lib/docker
sudo rm -rf /var/lib/containerd

sudo docker pull portainer/portainer-ce

sudo docker run -d -p 9000:9000 \
--name portainer --restart always \
-v /var/run/docker.sock:/var/run/docker.sock \
-v portainer_data:/data portainer/portainer-ce

docker ps

​sudo docker restart portainer

sudo usermod -aG docker ${USER}
