Can't deploy Rails App, push fails (PG::ConnectionBad: could not connect to server: Connection refused)
Hi, after playing with DigitalOcean for a while I am setting up an instance for my customer and I am unable to push the app, because of database error.
PG::ConnectionBad: could not connect to server: Connection refused
Is the server running on host "127.0.0.1" and accepting
TCP/IP connections on port 5432?
Which seems weird, since I bet the port is different on DO, but I don’t see how this can be if dokku/docker replaces the database.yml?
My database.yml is almost the same as on my other app which runs just fine.
development:
database: cttv
adapter: postgresql
user: michal
host: localhost
test: &test
database: cttv_test
adapter: postgresql
user: michal
host: localhost
production:
database: cttv
adapter: postgresql
user: michal
host: localhost
cucumber:
<<: *test
I think I did all the steps, but let me know if something is missing:
- installed postgres
- created database
- linked my app
- added rails_12factor to gemfile
- relinked the app with db to be sure with a script
Listing the processes reveal postgres should be running:

The app name is ‘dev’ since I want to see it on dev.mydomain.com, the pg logs:

One thing I know is different though is that I have set only the A record of dev.myserver.com, not the myserver.com itself, since there is still the old app running on heroku which I’ll then want to switch to DO, when the deploy is successful.
But that shouldn’t affect anything, right?
