Permission denied error when pinging inside Docker container
Question
I have just installed Docker on Ubuntu 18.04, and I cannot get access to outside networks from within my container.
I ran docker run --rm -it ubuntu:trusty ping 192.168.1.1 which yields: socket: Permission denied
On the other hand, the command docker run --rm -it ubuntu:trusty whoami yields root as expected, meaning the problem occurs inside the container.
How can I debug this?
Thanks in advance.
