very weird bug with containers inside virtual box

[rande]

Hello,

I have a working setup on Docker for Mac + Modd in a docker-compose file to restart 2 services: api and ssr. modd is working fine.

Now, I am testing the same code inside a VirtualBox VM with docker, modd only "see" changes for one service (randomly, or there is a race condition somewhere) so it is either api or ssr which get the notification.

To make it works, I switch to inotifywait, and both containers "see" the notification. So, there is a bug with modd (I have tested version 0.5 and 0.7 of modd) but I cannot understand why.

Subject: [PATCH] feat(dx): experiment vagrant box
