Docker Network inside a container partially working

Docker Engine General
1

I have running the “FROM php:5.6-apache” container with my own php application. That works. But one part didn’t. My application can not use the network.

If i run manualy

docker run -t -i myapp ping 8.8.8.8 it
that works great. But if my app does it like

$ping = exec(“ping -c 1 -s 64 -t 64 8.8.8.8”);
then it doesen’t.
