How to set up the mirror URL for downloading?

Rancher
1

Hi Forum,
I am new to Rancher and I am trying to set up Rancher in my local environment. I am using Docker to start Rancher with docker run -d --privileged -p 80:80 -p 443:443 -v /opt/data/rancher_data:/var/lib/rancher --restart=always --name rancher-285 rancher/rancher:v2.8.5; however, after starting the Rancher I found out logs of inaccessible errors of the container below

I am sure it was caused by my local network connection…therefore, I wanted to mirror another available URL for git.rancher.io...; so Rancher can connect to the URL correctly.

If you could give any suggestion or documentation on this?

Thanks in advance!
