-    - Get logs from file and merge with docker stdout
-- Mix Logs of Unbound
+- Golang binary to setup the container at start, and:
+  - Mix logs of unbound, tinyproxy, shadowsocks and openvpn together somehow

 - Maybe use `--inactive 3600 --ping 10 --ping-exit 60` as default behavior
 - Try without tun
