Running expose in Docker for another container fails

[TiiFuchs]

Hi,

I tried to run expose in a Docker container that is linked to a nginx webserver. I ran expose share nginx .... Note that "nginx" is the hostname of the container that serves the website and it is reachable via curl etc.

But expose cannot resolve the hostname "nginx", because in app/Client/Http/HttpClient.php in line 69 the dns ip is fixed as '127.0.0.1', which is not how it's configured in the Ubuntu system I ran expose on.

I found out that docker configured the dns to be 127.0.0.11 in /etc/resolv.conf, and when I changed this IP address in HttpClient.php to the correct one, everything worked fine. I also tried to remove the DNS IP address and it worked too.

So I guess it should be removed...? So the DNS resolver of the system is beeing used.

This was fixed then reverted for some reason, so the bug is back on latest version, i added a comment on the PR that the regression was made:

Reverting to 1.4.1 works.
