Hi,

I have installed controller-0 and bootstrap was failed at 'Download images
and push to local registry'.

I noticed that, dns resolution is failing in the controller but not in the
host.
controller-0:~$ dig docker.io

; <<>> DiG 9.9.4-RedHat-9.9.4-72.el7 <<>> docker.io
;; global options: +cmd
;; connection timed out; no servers could be reached
controller-0:~$ ping quay.io
PING quay.io (3.233.133.41) 56(84) bytes of data.

--- quay.io ping statistics ---
3 packets transmitted, 0 received, 100% packet loss, time 2054ms

I can ping from the controller.
I have added following entries to iptables but no luck.

sudo iptables -A OUTPUT -p udp -d 8.8.4.4,8.8.8.8 --dport 53 -m state
--state NEW,ESTABLISHED -j ACCEPT
sudo iptables -A INPUT  -p udp -s 8.8.4.4,8.8.8.8 --sport 53 -m state
--state ESTABLISHED     -j ACCEPT
sudo iptables -A OUTPUT -p tcp -d 8.8.4.4,8.8.8.8 --dport 53 -m state
--state NEW,ESTABLISHED -j ACCEPT
sudo iptables -A INPUT  -p tcp -s 8.8.4.4,8.8.8.8 --sport 53 -m state
--state ESTABLISHED     -j ACCEPT

I am not sure if my network configuration is correct.

controller-0:~$ ip route list
default via 10.10.10.1 dev ens3
10.10.10.0/24 dev ens3 proto kernel scope link src 10.10.10.3
169.254.0.0/16 dev eth1000 scope link metric 1002
169.254.0.0/16 dev eth1001 scope link metric 1003
169.254.0.0/16 dev ens3 scope link metric 1004
169.254.0.0/16 dev ens4 scope link metric 1005
172.17.0.0/16 dev docker0 proto kernel scope link src 172.17.0.1 linkdown

Following is my local routing configuration and host IP is 192.168.10.100.
$ ip route list
default via 192.168.172.3 dev eno1 proto static metric 100
10.10.10.0/24 dev stxbr1 proto kernel scope link src 10.10.10.1
192.168.122.0/24 dev virbr0 proto kernel scope link src 192.168.122.1
192.168.10.0/24 dev eno1 proto kernel scope link src 192.168.10.100 metric
100
