hi guys.i'm live in china ,so So I pull my docker mirror very, very slowly. i want set mirror  use the following command

“

mkdir -p /etc/docker

tee /etc/docker/daemon.json <<-'EOF'

{

"registry-mirrors": ["https://docker.mirrors.ustc.edu.cn"]

}

EOF

”

Then I restart my docker servers，It works 100 times faster。

Now the problem is, once I restart the nas, the file /etc/docker/daemon.json , failed to save....i used  winscp to view the file. It doesn't exist

so ,Is there a kind person who can help me

User Scripts plugin 

that was really helpful, thanks very much!

 

here is the working script (tested on unRaid 6.8.2):

#!/bin/bash
#name=docker.registry_mirrors

# prepare folder
mkdir -p /etc/docker

# update mirror
tee /etc/docker/daemon.json << EOF
{
  "registry-mirrors": ["https://docker.mirrors.ustc.edu.cn"]
}
EOF

# restart docker service if necessary
is_docker_running=$(/etc/rc.d/rc.docker status | awk 'NR == 1 {print} ' | grep running)
echo $is_docker_running
if [ ! -z "$is_docker_running" ]; then
	/etc/rc.d/rc.docker restart
fi

this is great, docker wasn't restarting when I ran this though. Got caught in an unmountable docker.img file. Hopefully that doesn't happen when array starts, it should create the file pretty quick before docker becomes active I'm guessing.

when user script quits, it always kills child process. docker service restart can't be put in the script as it will kill it in the end.
