Accessing the Internet when Minikube

[Vaiden Logan]

I have a Fabric VM with Minikube and Docker installed. I start minikube with “minikube start”. When I try to ping any IP address on the internet (I’ve been trying 8.8.8.8), the packets never get a response. Pinging the IP of the host the pod is running on works fine.

What special configuration do I need to do (maybe a proxy?) to access the Internet?

Hello,

This depends on which site your VM sliver is ending up. It is most likely you are on an IPv6 management site in which case it is worth looking at your DNS setup. By default the DNS servers *should* resolve IPv4 sites using our Nat64 capability, but it sometimes depends on the image.

You can also try manually configuring your DNS to use nat64.net setup.

If you are trying to reach IPv4 (8.8.8.8) from inside a container, then the issue likely is that you need to enable IPv6 in the container network since the management network you are on is IPv6.

Thank you. It turns out Minikube doesn’t support IPv6 at all, which is a surprise to me. Thank you for your reply.

You can test this on one of the IPv4 sites (e.g. I believe MAX or TACC) – if it works there, but not on  other sites, the issue is IPv6. You should easily be able to tell if a site is IPv4 by the management IP address you are given when you create a slice (we really should make a list, but it’s pretty short).
