various errors while following instructions from readme

[ninrod]

I'm on arch linux. After issuing docker-compose pull and docker-compose run --name wscef wscef, I got this error:

wscef-docker $ docker-compose run --name wscef wscef
WARNING: The HOSTNAME variable is not set. Defaulting to a blank string.
Creating network "wscefdocker_default" with the default driver
No protocol specified
Failed to connect to Mir: Failed to connect to server socket: Arquivo ou diretório não encontrado

/home/ff/startup.sh: linha 26: /usr/local/bin/warsaw/core: Arquivo ou diretório não encontrado
wscef-docker $

what can I do now?

If using Fedora and variants disable SELinux but is possble using feature... adding a Z arguments on mount points of docker, explained in this Issue https://github.com/farribeiro/wscef-docker/issues/9#issuecomment-320833518

@farribeiro, are you talking about this snippet?

- <src>:<dest>:Z or - <src>:<dest>:ro,Z

What is this exactly doing?

ps: I see that you prefer english. I'll edit my post accordingly.

Take a look on the docker-compose.yml

[ninrod]

Yes I've looked into it. I still don't know what the Z parameter does.
