I just installed docker on CentOS 8. Everything went fine, I’ve run the hello_world test container and the result was successful.
The issue is that inside the containers I cannot resolve any DNS queries. For example when I type ping 8.8.8.8 (on any kind of base container such as ubuntu os centOS) i get the correct answer but when I try running ping google.com I don’t get any answer, meaning that the container is unable to resolve the DNS for any URL.
I’ve also tried running a base container like this:
docker run busybox ping -c 1 192.203.230.10
ang I’m getting this (correct) output:
[server@localhost ~]$ docker run busybox ping -c 1 192.203.230.10
PING 192.203.230.10 (192.203.230.10): 56 data bytes
64 bytes from 192.203.230.10: seq=0 ttl=51 time=32.413 ms
--- 192.203.230.10 ping statistics ---
1 packets transmitted, 1 packets received, 0% packet loss
round-trip min/avg/max = 32.413/32.413/32.413 ms
But now trying resolving the domain google.com with the command:
docker run busybox nslookup google.com
I get this output:
