How can I debug php mounted to a container running on docker beta for mac

Question

I have spent half the day trying different things including this solution I came across on gist.github.com

I have a docker-compose file which mounts a folder containing my client and server projects:

 volumes:
    - ~/projectx:/projectx

my docker php.ini contains the following xdebug options

[xdebug]
xdebug.remote_enable=1
xdebug.remote_port=9000
xdebug.remote_connect_back=On
xdebug.var_display_max_children = 999
xdebug.var_display_max_data = 999
xdebug.var_display_max_depth = 100

I have the xdebug chrome extension installed

In my mac host file I have the following 127.0.0.1 localhost dtest.xxx.com so I can access my web app (and other docker web apps) through dtest.xxx.com which all works to run the app

In Phpstorm (version 2016.1.2) In preferences -> Languages & Frameworks -> PHP -> Servers I have :

host = dtest.xxx.com, port=80 , Debugger = Xdebug
Use path mappings is checked and I have
      File/Directory set to /Users/<myname>/projectx/server
      Absolute path on the server is set to /projectx/server

I have tried setting the xdebug.remote_host to my macs ip obtained from ifconfig as well as trying the ip in /Users/<myname>/Library/Containers/com.docker.docker/Data/database/com.docker.driver.amd64-linux/slirp/host

But I cannot hit a breakpoint , I have even added xdebug_break() double check. I am also running the latest docker beta Version 1.12.0-rc3-beta18 (build: 9996)

I would very much appreciate anyone's help, it's a real blocker for me.

If any further information is required I am happy to provide.

UPDATE 2:

As pointed out by @Rashidul , Since 17.06 docker for Mac, you can replace xdebug.remote_host="192.168.65.1" with xdebug.remote_host="docker.for.mac.localhost"

UPDATE: The Correct way

so I eventually figured out that my xdebug settings in docker should be

xdebug.enable=1
xdebug.remote_enable = 1
xdebug.idekey="PHPSTORM"
xdebug.remote_port=9000
xdebug.remote_host="192.168.65.1"
xdebug.remote_connect_back=0

where 192.168.65.1 is the entry found in ~/Library/Containers/com.docker.docker/Data/database/com.docker.driver.amd64-linux/slirp/host

In recent update the above no longer exists, to get the Docker host IP I know use the below my .profile

export DOCKER_HOST_IP=$(ipconfig getifaddr en0)

Also make sure to set the idekey correctly in the chrome extension, in my case PHPSTORM
With this I no longer require the ssh tunnel

Original Solution:

The workaround I used was to open up an ssh tunnel to the docker container running php using a command like, in my case I have the docker container ssh port mapped to 12 hence the -p 12

ssh -R 9000:localhost:9000 [email protected] -p:12
