Answer 1

Before reading this answer just let you know, it's my 2nd day of learning docker, It may not be the perfect help for you.

This error may also occur when the ping package is not installed in the container, I resolved the problem as follow, bash into the container like this

docker container exec -it my_nginx /bin/bash

then install ping package

apt-get update
apt-get install inetutils-ping

This solved my problem.

Answer 2

Please use alpine image of nginx:

docker container run -d --name my_nginx_name nginx:alpine

docker container run -d --name my_nginx_name2 nginx:alpine

Then try to ping using below command:

docker container exec -it my_nginx_name ping my_nginx_name2
