Lesspass: Building for ARM(rpi) & Docker fails

Hello,

I wanted to run lesspass with docker on my rpi but sadly the building fails at Step 5

$ docker-compose up
Creating network "containers_default" with the default driver
Creating volume "containers_www" with default driver
Creating volume "containers_postgresql" with default driver
Creating volume "containers_profiles" with default driver
Building webserver

The images wont run that easy like said in #215

We can close this now, it should work on raspberry pi too

Seems like the package epel-release could not be found. Some googleing showed that the repo of that package must be explicitly added for ARMv7 like showed here https://stackoverflow.com/questions/35925066/epel-repository-for-arm7 because the is no offical repo for armhf.

I have no centos knowledge so maybe some one can fix this.
Thanks :)
