ubuntu系统，修改/etc/docker/daemon.json，修改如下。

{
	builder: {
		gc: {
			defaultKeepStorage: 20GB,
			enabled: true
		}
	},
	experimental: false,
	features: {
		buildkit: true
	},
	registry-mirrors: [
		"https://docker.mirrors.ustc.edu.cn",
		"https://mirror.baidubce.com",
		"https://docker.m.daocloud.io",
		"https://mirror.ccs.tencentyun.com",
		"https://docker.nju.edu.cn",
		"https://docker.mirrors.sjtug.sjtu.edu.cn",
		"https://mirror.gcr.io",

		"https://docker.jsdelivr.fyi",
		"https://dockertest.jsdelivr.fyi",
		"https://mirror.aliyuncs.com",

	]
}

###【修改后需要重启】：

sudo systemctl daemon-reload
sudo systemctl restart docker
sudo systemctl status docker
sudo docker info
