rkt networking on ubuntu

Question

I am trying to run a simple rkt container on ubuntu 16.10. I am having some networking problems. Here are the commands I ran.

sudo rkt run --interactive quay.io/coreos/alpine-sh

Then running:

/ # ping google.com ping: bad address 'google.com' / # ping 8.8.8.8 PING 8.8.8.8 (8.8.8.8): 56 data bytes 64 bytes from 8.8.8.8: seq=0 ttl=58 time=6.815 ms

After coming out: sudo rkt list UUID APP IMAGE NAME STATE CREATED STARTED NETWORKS 4d35bf55 alpine-sh quay.io/coreos/alpine-sh:latest exited 40 seconds ago 39 seconds ago

As you can see network tab is empty. Here is my iptables:

sudo iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination
Chain FORWARD (policy ACCEPT) target prot opt source destination
ACCEPT all -- anywhere 172.16.28.0/24
ACCEPT all -- 172.16.28.0/24 anywhere
Chain OUTPUT (policy ACCEPT) target prot opt source destination

Answer 1

try adding --dns

sudo rkt run --interactive quay.io/coreos/alpine-sh --dns=8.8.8.8

btw 8.8.8.8 is the address of google's DNS server
