Access outside LDAP server from docker container

[HELP]

This is my 1st post in Docker Community. If you are difficult to understand my sentence , i want you to forgive.

i want to build Web-server (use apache on centos 7) , MySQL and phpMyAdmin container by docker-compose . and i want access outside LDAP server.

but i use bridge network then i can’t access outside LDAP server from Web-server. incidentally i can’t accsess www.google.com by ping command.

how should i do ?

docker -v is Docker version 17.12.0-ce, build c97c6d6
docker-compose -v is docker-compose version 1.19.0-rc2, build a186c31
cat /etc/centos-release is CentOS Linux release 7.4.1708 (Core) ← this is runnning Docker contaner server .

i carried out the contents of this web site.
https://bugzilla.redhat.com/show_bug.cgi?id=1033606

so that my problem was setted.

GoodBye!
