[Alpine Linux]: DNS resolution inside an Alpine Linux-based Codespace sporadically fails

[legomushroom]

Apline Linux kernel queries a random nameserver as oppose to using nameservers in sequence as other Linux distros would do. This causes some of DNS requests to go past our defined nameserver.

🔨 Workarounds

1. Either add explicit ip-address hostname mapping to /etc/hosts file inside a Codespace. This will help DNS resolution process.

2. Or modify the /etc/resolv.conf file to keep only the VPN Gateway-defined nameserver (the one marked with # Codespaces VPN Gateway comments)
