The volumes section of elasticsearch service looks OK to me:
/opt/trains/data/elastic_7:/usr/share/elasticsearch/data

What about the UID for epdadmin user? 'id -u epdadmin'

epdadmin@epdadmin-desktop:~$ id -u epdadmin
1000

WobblyCrab70 what command are you using to start the docker-compose?

I will use whatever command you tell me and write it down forever

I used docker-compose up and another one i can find if i look for it

Can you try doing sudo docker-compose up ?

should I be in some path for this?

i am in opt/trains

I am getting these errors infinitely

It starts like this:
WARNING: The TRAINS_HOST_IP variable is not set. Defaulting to a blank string. WARNING: The TRAINS_AGENT_GIT_USER variable is not set. Defaulting to a blank string. WARNING: The TRAINS_AGENT_GIT_PASS variable is not set. Defaulting to a blank string. Starting trains-elastic ... Starting trains-mongo ... Starting trains-fileserver ... Starting trains-redis ...

even though i have configured the WARNINGS as the guide told me

Are the errors in the elastic log the same? (it's hard to see in your pasted log)

Oh, yes, it seems they are

and all the paths are in /opt/trains/... ?

Starting trains-elastic ... done

I mean, you're running from /opt/trains ?

above dump is from sudo docker-compose up

i really have to go, I am greatful for your dedicated help. any chance to set a concentrated time for this tomorrow?

So that's the issue - the docker-compose.yml assumes everything resides in /opt/trains , not in your home folder

Just put everything there and it'll work 😄

cp -rf ?

I'll have to check later 🙂 thanks a lot

I'd do the setup process again (i.e. mkdir etc.)

just to make sure you have the folders set up right

ok thanks
