解决ubuntu docker拉取环境失败问题

sudo tee /etc/docker/daemon.json <<-'EOF'
{
    "registry-mirrors": [
    	"https://docker.m.daocloud.io",
    	"https://docker.imgdb.de",
    	"https://docker-0.unsee.tech",
    	"https://docker.hlmirror.com",
    	"https://docker.1ms.run",
    	"https://func.ink",
    	"https://lispy.org",
    	"https://docker.xiaogenban1993.com"
    ]
}
EOF

或者打开文件vim /etc/docker/daemon.json

{
    "registry-mirrors": [
    	"https://docker.m.daocloud.io",
    	"https://docker.imgdb.de",
    	"https://docker-0.unsee.tech",
    	"https://docker.hlmirror.com",
    	"https://docker.1ms.run",
    	"https://func.ink",
    	"https://lispy.org",
    	"https://docker.xiaogenban1993.com"
    ]
}
