Heroku runs on dynos which they describe as “a lightweight container running a single super-specified command”. In essence, Heroku abstracts the container away from the user and puts a sandbox up around what it can do. Docker is an opensource container standard that can run just about anywhere.

.

Correspondingly, does heroku use containers?

The Heroku Platform uses the container model to run and scale all Heroku apps. The containers used at Heroku are called “dynos.” Dynos are isolated, virtualized Linux containers that are designed to execute code based on a user-specified command.

One may also ask, does heroku use Kubernetes? Heroku lets app developers spend 100% of their time on their application code, not managing servers, deployment, ongoing operations, or scaling; Kubernetes: Manage a cluster of Linux containers as a single system to accelerate Dev and simplify Ops. Agile deployment for Ruby, Node.

Also question is, how do you deploy a container?

Deploy Docker Containers

  1. Step 1: Set up your first run with Amazon ECS.
  2. Step 2: Create a task definition.
  3. Step 3: Configure your service.
  4. Step 4: Configure your cluster.
  5. Step 5: Launch and view your resources.
  6. Step 6: Open the Sample Application.
  7. Step 7: Delete Your Resources.

How many Heroku dynos do I need?

Well, that depends. Most production apps need at least a web process and a background worker process for things like sending email and processing payments. That's two dynos running for 744 hours per month, which exceeds your 1,000 hour allotment.
