I had trouble with some of the Gems. I removed Gemfile.lock and ran Bundle Update. Also had to install RVM to manage Ruby Versions.
Next problem: Can't get PG to run correctly (though admittedly I'm very bad at this sort of task). Here is my error:
could not translate host name "db" to address: Name or service not known
Couldn't create 'myapp_development' database. Please check your configuration.
rake aborted!
PG::ConnectionBad: could not translate host name "db" to address: Name or service not known
Not sure if you got this to work zsilverzweig, but I figured I'd comment here in case anyone else comes upon this post.
I had to add the following to the docker-compose.yml file to get this to work:
Under the db service
ports:
# expose 5432
- 5432:5432
# I honestly can't remember if this was necessary,
# but I also have these environment variables set.
environment:
POSTGRES_USER: postgres
POSTGRES_PASSWORD: ${DB_PASS}
POSTGRES_DB: db
in the backend service:
environment:
# THIS IS KEY. I pass in docker-machine ip as the DB_HOST
# when I run docker-compose. this is necessary because
# docker-machine is running on virutalbox, and so localhost
# doesn't work with any of these, you need to be referencing
# the external IP of the virtualbox.
# ex: DB_HOST=$(docker-machine ip) docker-compose up backend
DB_HOST: ${DB_HOST}
# I did this so I could link the db pass with the one given the db service
# above. Not setting a password didn't work for me, but in theory it should.
DB_PASS: ${DB_PASS}
The biggest issue I had was figuring out that the virtualbox IP needed to be referenced directly. Once I figured that out, I could at least log onto the psql console and change the password.
