curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg

# Add the repository to Apt sources:
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" | \

常见问题 ​

修改默认网桥的网段 IP ​

默认网段是172.17.0.1/16，可能会发生冲突，所以需要手动更改。

编辑或新建配置文件

sh
vim /etc/docker/daemon.json
json
{
	"bip": "192.168.6.1/24"
}
