Deploying pimentaCHAT on Heroku

Two ways to deploy pimentaCHAT to Heroku:

  • easy one click
  • customized command line

One Click automatic deploy

Try clicking the button below, and either login or create a new account, then follow all prompts.

One-Click Deploy


If everything goes well, you will have your own instance of pimentaCHAT running.

If not, please raise an issue.

Update existing One-Click Heroku Deployment

Prepare for updates:

# create local repo pointing to the Heroku remote
heroku git:clone --app YOUR_HEROKU_APPNAME && cd YOUR_HEROKU_APPNAME

# attach the GitHub repository of pimentaCHAT as a new remote
git remote add origin https://bitbucket.org/pimenta-group/pimenta.chat

From now on you can simply update your Heroku instance by running:

git pull origin master # pull down the latest version from GitHub
git push heroku master # push all updates back to your Heroku app instance

Customized command line for developers

This is the option that gives you full control. It is the preferred option for developers.

First make sure you have the following installed:

  • git
  • Heroku CLI

Next, checkout the latest version of pimentaCHAT:

git clone https://bitbucket.org/pimenta-group/pimenta.chat

Change into the pimentaCHAT directory, and create your Heroku app:

heroku apps:create  --addons mongolab:sandbox,logentries:le_tryit -b https://github.com/pimentachat/heroku-buildpack-meteor <your app name>

Choose <your app name> carefully, as your pimentaCHAT will then be accessible at:

https://<your app name>.herokuapp.com/

Next, you MUST set the ROOT_URL environment variable:

heroku config:add ROOT_URL=https://<your app name>.herokuapp.com/

If your app failed to start, check and make sure you have ROOT_URL set.

Heroku app deployment is triggered by git commits - to Heroku’s repos, and not GitHub.

You are almost ready to deploy and stage your own instance. But you must first wire up the git repos to Heroku.

git remote add heroku https://git.heroku.com/<your app name>.git

Finally, deploy and stage your app by:

git push heroku master

pimentaCHAT should now be running.

Got Problems

  • Set the repository as the buildpack URL:
heroku buildpacks:set https://github.com/AdmitHub/meteor-buildpack-horse.git
  • Then try again
git push heroku master
  • Still got problems, please raise an issue.


  • To add any service to an app, even if it is free, you will need to register a valid credit card with Heroku. pimentaCHAT needs both mongolab and logenteries services.
  • Heroku (actually CloudFoundry) uses custom buildpacks to stage applications. The buildpack used by pimentaCHAT can take a very long time to build - since it needs to download Meteor and build the server image every time.
  • You must set the ROOT_URL environment variable, as shown above, otherwise the server side will crash.
  • Note mongolab’s free sandbox plan does not support oplog tailing - check other plans if you need oplog.
  • If you are scaling to multi-dynos on Heroku, and you have clients/customers still using older browsers that do not support WebSocket, you need to be mindful of sticky session support (BETA) on Heroku - see sticky sessions on Heroku.
