You have to rely on something to check if our services are up and running. Wether it’s a monitoring tool, a loadbalancer checking for healthy endpoints, …
I recommend using a a route named /ping and use good old http request for checking.
This way – imho – you have a stronger guarantee that your service is up and running.
PS: Don’t forget to disable logging for this route 😉
When pushing changes to your website you want to test them in an environment similar to your production one – without the fear of breaking something for your customers: voilà, staging.

Virtualbox is usually not my first choice with vagrant but https://github.com/ceph/ceph-ansible didn’t work out of the box with the vmware-fusion provider so I’m sticking with it for now.

I recently ran into a problem with a compile-on-filesystem-change application on boot2docker. Due to the layered structure of boot2docker (Host->VM->docker) the mechanics required for inotify are not working.
Luckily there exists a solution: https://github.com/brikis98/docker-osx-dev
I use docker-compose – so after installing docker-osx-dev, just run it in the folder containing the docker-compose.yml and docker-osx-dev finds the correct folders to watch.
