Running Heroku Console does not start

Question

I am trying to run Heroku console, but in the console, I get the message "Running console attached to terminal" but the console doesn't start.

In the Heroku logs, I get the error:

 Error: no child processes attached.

Any help?

Answer 1

I just had a thread with Heroku support about my similar issue, here was their response, which worked for me.

So this is a bamboo app. You can either do

$ heroku console

which will tap into a running web dyno, or you can run a new console as a one-off process with:

$ heroku run bundle exec rails console

On cedar apps you'd also be able to do

$ heroku run console

which also starts a one-off process, because the console process type would be implied by the rails buildpack or declared in your Procfile. It amounts to the same as the previous line.

Answer 2

I was experiencing same issues.
Try

heroku run rails console

in Rails >=3

Happy coding :)

Answer 3

Try

$ telnet rendezvous.heroku.com 5000 

to test the net enabled access to that port. They mention that filtered-port issue on their guide

Answer 4

I think this is the same problem you're describing and it has an accepted answer which seemed to fix the issue for the guy that posted the question :-)

heroku run console returns 'Error connecting to process'

Answer 5

I had this problem before I'd actually pushed my code to heroku.

Once I successfully pushed and started everything (bundle, rake etc.) the console actually worked.

Answer 6

Do this and then try In Procfile

web: bundle exec unicorn_rails -p $PORT -c config/unicorn.rb

In unicorn.rb

worker_processes 2 preload_app true timeout 30

@resque_pid = nil

before_fork do |server, worker| @resque_pid ||= spawn("bundle exec rake environment resque:work QUEUE=*") end

after_fork do |server, worker| ActiveRecord::Base.establish_connection end
