Why is my middleman heroku app ignoring the Procfile? - heroku

I've been struggling trying to launch my middleman repo to heroku. I've followed a tutorial http://randomerrata.com/post/56163474367/middleman-on-heroku, but have had continued issues. Although installing the puma gem, for some reason the procfile is being ignored and the heroku app keeps pointing to
web bundle exec sudo unicorn_rails -c ./config/unicorn.rb -p $PORT -D --env production
Any idea how to get this thing to stop pointing to the unicorn rails and use puma?

Perhaps it would be worth checking out middleman-heroku as a different route to take. Alternatively I would check that your Gemfile.lock is up to date and committed.

I would try tailing the logs with heroku logs -t to see if you can see what's happening.
Is your Procfile called Procfile with a capital P?
What does it look like, can you post it here?
My Procfile has web: bundle exec puma -p $PORT. Is Puma listed in your Gemfile?

Using Sidekiq and Passenger in same Heroku Dyno

I have a simple web app on heroku running on Passenger and I am trying to make the emails asynchronous. I set it all up with Sidekiq in my dev environment and then I realized I have to start a new dyno on Heroku to run the Sidekiq worker and have to pay $34/m. I am trying to see if I can run Sidekiq on the web dyno with Passenger and save the $34/m cost for now till its worth that investment.
I found a post here that explains how to do this with Unicorn. I am wondering if I can do the same thing with Passenger.
If that doesn't work I will look at using sucker_punch or use unicorn instead but will be good if I can Sidekiq working on the same dyno with Passenger.
I am on rails 3.1, sidekiq 3.1.4 and passenger 4.0.5 - can upgrade here if I have to.
Thanks for your thoughts.

You can. There's no difference between Passenger and Unicorn when it comes to achieving this goal. Instead of specifying web: bundle exec unicorn ... in your Procfile, you just set web: bundle exec passenger in your Procfile. Instead of setting a Unicorn config file, you set equivalent Passenger command line arguments or configuration.

Heroku: where did my gems go?

I have been deploying a Rails 3.2 application to heroku for several weeks now. I have also been executing rake tasks on the Cedar stack where my application is located.
One day after a deploy I noticed that rake was no longer working. I get, for example, the following:
$:~/dev/my_project$ heroku run rake -T
Running `rake -T` attached to terminal... up, run.7566
bundler: command not found: rake
Install missing gem executables with `bundle install`
Trying to run commands with bundle exec yields the same results.
What I've tried:
heroku run bundle install. This works and informs me that gems were installed into ./vendor/bundle. However, heroku run ls ./vendor/bundle yields only the following:
$:~/dev/my_project$ heroku run ls ./vendor/bundle/
Runningls ./vendor/bundle/attached to terminal... up, run.3458
bin ruby
bundle package. Although the deployment works it does not help my problem.
fiddling around with the rubygems-bundler gem (although I think this is now part of core bundler). This does not seem to have any effect.
On Heroku, gems are installed within the vendor/bundle/ruby/<version>/gems directory. I just checked my Heroku instance and confirmed this.
You are going to want to use bundle exec rake task because the gems are not in the users PATH.

How to run Rack-based application (not Rails) with Unicorn

How can I run a Rack-based application (not Rails) with unicorn? Let's assume I have a "hello world" response simple rack app with the name of server.ru, and config file at the same directory with the name of unicorn.conf, how am I supposed to run it? In Thin, for example, I would do something like:
bundle exec rackup server.ru -s thin -E production -p 4001
How would I do the same to run under Unicorn?
Unicorn does not give any special treatment to Rails 3+ applications, so the behavior is exactly the same for Rails 3+ applications and non-Rails Rack applications. Just run
unicorn
in your app's root. To run with a specific port, pass -p/--port with the port:
unicorn -p 4001
You can also specify the rackup file:
unicorn server.ru
You can see all the options by running unicorn --help. Of course, you should prepend bundle exec to these commands as needed by your setup.
You can make a setting file for unicorn like this:
working_directory "/path/to/your/app"
listen 4001
pid "/tmp/unicorn.pid"
And then launch unicorn with the following command:
unicorn -c /path/to/your/setting/file.rb

Heroku not loading bundler for non-web ruby app

I have a program that I wrote using ruby. It doesn't have any web interface, but I use bundler for dependency management.
On my local system, running the app is as simple as typing rake app:start, and it loads up just fine.
When I deploy to heroku, however, my app crashes with a cannot load such file -- bundler error.
My Procfile looks has this entry app: bundle exec rake app:start.
Any help is greatly appreciated.
The problem was that Heroku was not changing the GEM_HOME field to the vendor/bundle directory.
By adding the following config vars to Heroku, my app ran as expected:
GEM_HOME: /app/vendor/bundle/ruby/1.9.1
PATH: /app/vendor/bundle/ruby/1.9.1/bin:bin:node_modules/.bin:/usr/local/bin:/usr/bin:/bin
Adding these was done via the heroku config:set CONFIG_NAME=VALUE command.

Heroku Cedar: how to stop using WEBrick

In my Gemfile I have:
gem 'thin'
But when I push my application to Heroku Cedar, WEBrick is still used ("Booting WEBrick" in logs).
Where might be a problem?
You just need to create a Procfile and add the following line:
web: bundle exec rails server -p $PORT thin -e $RACK_ENV
Push that to Heroku and you'll be all set.
