Ubuntu in Heroku

▶️🐳 This is a guide on how to use Ubuntu on Heroku.

Note that this guide does not use pure Ubuntu from docker rather uses a ubuntu based on OS made by Heroku itself

Usage

Here's the steps to use Ubuntu on Heroku:

  1. Loging into Heroku Login:
$ heroku login -i
heroku: Enter your login credentials
Email: me@example.com
Password: ***************
Two-factor code: ********
Logged in as me@heroku.com
  1. Loging into Heroku containers:
$ heroku container:login

Login Succeeded
  1. Creating a Heroku Create: (Not requied if you aleardy have a app)
$ heroku create
Creating safe-journey-10471... done, stack is heroku-18
https://safe-journey-10471.herokuapp.com/ | https://git.heroku.com/safe-journey-10471.git
  1. Pushing the Heroku App:
$ heroku container:push worker -a safe-journey-10471
=== Building worker ...
...
...
Your image has been successfully pushed. You can now release it with the 'container:release' command.

Note: here we are using worker and not web process id because web require a listening port, we are also using the app from berfore with the -a parameter. You should use your app name created

  1. Releaseing the Heroku App:
$ heroku container:release worker -a safe-journey-10471
Releasing images worker to safe-journey-10471... done
  1. Scaling your app to work as a worker
$ heroku ps:scale worker=1 
Scaling dynos... done, now running worker at 1:Free
  1. Checking if the worker in working:
$ heroku ps -a safe-journey-10471
Free dyno hours quota remaining this month: 549h 52m (99%)
Free dyno usage for this app: 0h 0m (0%)
...
...
=== worker (Free): /bin/sh -c bash\ heroku-exec.sh (1)
worker.1: up 2020/01/19 04:35:29 -0800 (~ 1m ago)
  1. Shell into your app!
$ heroku ps:exec -a safe-journey-10471 -d worker.1
Running this command for the first time requires a dyno restart.
Do you want to continue? [y/n]: y
Initializing feature... done

/ $ uname -a

And there you go, now you have your own Heroku container running Ubuntu!
