 3、顺序安装相关的包

sudo dpkg -i libltdl7_2.4.6-2_amd64.deb 
sudo dpkg -i docker-ce-cli_18.09.6~3-0~ubuntu-bionic_amd64.deb 
sudo dpkg -i containerd.io_1.2.5-1_amd64.deb
sudo dpkg -i docker-ce_18.09.6~3-0~ubuntu-bionic_amd64.deb

 4、验证是否成功

docker -v

 5、docker ps 或 docker images遇到问题permission denied

报错信息

Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.39/images/json: dial unix /var/run/docker.sock: connect: permission denied

 解决方案：

（1）添加docker组

（2）添加用户到docker组

（3）切换用户

sudo groupadd docker
sudo usermod -aG docker ${USER}
su ${USER}

备注：

①${USER}表示用户名
