The default docker-compose.yml in the examples folder does NOT work on Windows (10). When running docker-compose up it errors out for every volume specification in the docker-compose.yml file with Cannot create container for service ${SERVICE_NAME}: invalid volume specification
Here's just one of the errors, it happens with all of the "volume" configs in the docker-compose.yml file:

ERROR: for librenms_rrdcached  Cannot create container for service rrdcached: invalid volume specification: 'H:\devel\librenms-docker\examples\compose\rrd-journal:/data/journal:rw'

Looks like we have to set this in our ~/Documents/WindowsPowershell/Microsoft.PowerShell_profile.ps1
...
$Env:COMPOSE_CONVERT_WINDOWS_PATHS=1
...

  1. Follow the above instruction to set the environment variable COMPOSE_CONVERT_WINDOWS_PATHS=1 in the specified Microsoft.Powershell_profile.ps1 script
  2. Modify the default docker-compose.yml in the librenms-docker examples folder, the following worked perfectly for me (note: I added the ports section to each service container so I could easily modify the published (windows host) port, it had no adverse affect by leaving the port specifications there. Ultimately, it's just more verbose):

@xorr0 I don't provide support for Windows for this Docker image but thank you for your report. I think this will help Windows users.

* I ran into this exact same issue with another project, and [filed an issue](https://github.com/netdisco/netdisco-docker/issues/25)

* The FIX is two-fold, as reported in the [docker-compose issues #4240](https://github.com/docker/compose/issues/4240#issuecomment-267746348):

Looks like we have to set this in our ~/Documents/WindowsPowershell/Microsoft.PowerShell_profile.ps1

1. Follow the above instruction to set the environment variable `COMPOSE_CONVERT_WINDOWS_PATHS=1` in the specified `Microsoft.Powershell_profile.ps1` script

Tried this on W10 server and the smtp one keeps crashing or restarting.
