Using Your Own Dockerfiles

Dockerfiles are often used for managing configuration and automating the build process for a service. If your repositories have Dockerfiles, it’s easy to get them set up in Runnable. At the end of this guide, you’ll have a running container for a repository, built from its Dockerfile.

Note: Using your own Dockerfiles is a great way to start using Runnable, but some features are reserved for apps that use Docker Compose:

  • Automatically creating isolated stacks for branches
  • Running automated tests

Adding Your Repository

From the Containers page, click the Add Services button and select a repository that uses a Dockerfile. We’ll be using the Dockerfile in the default branch (set on GitHub) to build and run a container. Later, you’ll be able to launch containers for additional branches of this repository.

Add Service

In the modal that appears, click the No Compose File tab. Then select Use a Dockerfile in your repo and type in the path for your Dockerfile, relative to the root of your repository. You’ll see a green check when we find a matching file.

Dockerfile Path

Then click the Create Environment button to continue.

Building your Dockerfile

In the next view, you’ll see the Dockerfile we imported from your repository.

Note: If your Dockerfile uses a private image, you’ll need to set up access to your registry so your container can build successfully.


Click Save & Build to start building your container. When your container’s build logs appear, you can click Done to close this view.

Using Your Containers

Once the container is running, you can interact with the terminal or open its URL to view its web output.


By default, you’ll also get new environments for branches of this repository when you push to GitHub. Pushes from other collaborators who have joined Runnable will also trigger new environments.
