+### How can I tell a container to connect to another container?
+
+**Static configuration**
+
+If you need to preconfigure a connection, use the *DOCKER_HOST* environment 
+variable. It will only work in the *environment* section of the service config:
+
+```json
+  "environment": {
+    "FOO_SERVER": "${DOCKER_HOST}"
+  }
+```
+
+**From running container**
+
+Lookup the IP on your host. On Linux you would do something like:
+
+```
+$ ip addr show docker0
+6: docker0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default 
+    link/ether 02:42:69:cd:44:2c brd ff:ff:ff:ff:ff:ff
+    inet 172.17.0.1/16 brd 172.17.255.255 scope global docker0
+       valid_lft forever preferred_lft forever
+    inet6 fe80::42:69ff:fecd:442c/64 scope link 
+       valid_lft forever preferred_lft forever
