I have deployed a rails 3.1 app to Heroku Cedar stack, and am trying to perform a:
heroku run rake db:migrate
it returns:
Running console attached to terminal... Error connecting to process
I also try to simply launch the console:
heroku run console
Any run command returns the same error.
Running console attached to terminal... Error connecting to process
Looking at the logs I get the error code:
2011-09-25T16:04:52+00:00 app[run.2]: Error R13 (Attach error) -> Failed to attach to process
When I heroku ps
to see the current processes, I can see my attempts are running:
Process State Command ------------ ------------------ ------------------------------ run.2 complete for 26m bundle exec rails console run.3 up for 27s bundle exec rails console run.4 up for 3s bundle exec rake db:create web.1 up for 46s bundle exec thin start -p $PORT -e..
But again each of them are raising exceptions:
2011-09-25T16:31:47+00:00 app[run.3]: Error R13 (Attach error) -> Failed to attach to process 2011-09-25T16:31:47+00:00 heroku[run.3]: Process exited 2011-09-25T16:31:48+00:00 heroku[run.3]: State changed from up to complete 2011-09-25T16:32:11+00:00 app[run.4]: Error R13 (Attach error) -> Failed to attach to process 2011-09-25T16:32:11+00:00 heroku[run.4]: Process exited 2011-09-25T16:32:12+00:00 heroku[run.4]: State changed from up to complete
Server Admin isnt my cup of tea, hence the decision to use Heroku.
Both Heroku docs and Googling have not led me down a path that give me much to go on.
Any ideas? This has not been my experience on the Bamboo stack.
My other errors are obviously related to DB migrations not being performed. Until I can run the rake tasks, I'm stuck moving forward.
I had the same problem, and although I did not solve the problem, I found a workaround.
Instead of using:
heroku run rake db:migrate
You can use:
heroku run:detached rake db:migrate
This runs the command in the background, writing the output to the log. When it is finished you can view the log for the result.
Not ideal, but when you are on an inadequate network, it will get you out of a hole :)
