[vinxenxo]

Hi there!! I'm trying to build and up a consul project with docker-compose

I have all the requisites installed
I follow all the instructions and I test it locally and consuls deploy to web and runs fine
but when build the containers on the same enviroment to run in a docker production env
get this error when execute

$ sudo docker-compose run app rake db:create
[...]
Successfully tagged consul_app:latest
consul_database_1 is up-to-date
Creating consul_app_1 ... error

**ERROR: for consul_app_1  Cannot create container for service app: create .: volume name is too short, names should be at least two alphanumeric characters

ERROR: for app  Cannot create container for service app: create .: volume name is too short, names should be at least two alphanumeric characters**

This is Dockerfile

# CMD [ "config/containers/app_cmd.sh" ]
CMD ["bundle", "exec", "rails", "server", "-b", "0.0.0.0"]

I try to figure out with volumes and so with all I can find online but no way
Thanks in advance

Hi @vinxenxo you could give a try with our docker related files >> https://file.participation.tools/f.php?h=3L36DBL5&d=1 works smooth for us (also added the .env file voor development) Cheers,

Thanks for the files @raoulkramer , I think there's a missing script, though:

Step 10/19 : COPY scripts/tmp-cleanup.sh /usr/local/bin/tmp-cleanup.sh
COPY failed: file not found in build context or excluded by .dockerignore: stat scripts/tmp-cleanup.sh: file does not exist

And the file doesn't come in the zip

hi @glicerico , Sorry my mistake, I was testing a script but that didn't work. So please take line 20 COPY scripts/tmp-cleanup.sh /usr/local/bin/tmp-cleanup.sh out of the dockerfile.

Quoting a comment in #3588 (by @asolera ):

I had the same problem here! Solved by changing the app/volume section of docker-compose.yml file to this:

 volumes:
      - "$PWD:/var/www/consul"
