Obsolete with Docker RC1
VPN is now supported: https://docs.docker.com/docker-for-mac/apple-m1/
Workaround for VPN Problem using Docker Tech Preview 1 on Apple Silicon
If you cannot pull from third party Docker registries on a VPN, then this is for you.
Error Message:
Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)
Usage:
Find out which utun interface your vpn uses by running if config:
ifconfig
Then look for a utun interface with an associated IPv4 address:
utun2: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1500
inet 192.168.50.14 --> 192.168.50.14 netmask 0xffffffe0
Then open the vpn.sh file and edit this line appropriately:
export UTUN_INTF="utun2"
Now execute the script to enable the workaround:
./vpn.sh
Note:
You have to run this script on every reboot.
