Cuber is an incredible automation tool that makes deploying your applications to Kubernetes a breeze. In this article, we will guide you step-by-step on how to use Cuber to streamline your deployment process.

What is Cuber?

Cuber is a Ruby-written automation tool designed to simplify the packaging and deployment of applications (regardless of the language or framework) on Kubernetes. Think of Cuber as a universal remote control for your applications; while many remotes have too many buttons that can confuse users, Cuber keeps it simple by providing a standardized and reliable approach. You just create a Cuberfile, write around ten lines of code, and execute cuber deploy to deploy your app seamlessly across any Kubernetes cluster.

Why Choose Kubernetes?

• Kubernetes can be up to 80% cheaper than platform-as-a-service options like Heroku.
• You have the flexibility to select from different cloud providers, preventing vendor lock-in.
• Kubernetes can scale applications of any size reliably.

Despite its complexities, Cuber simplifies Kubernetes deployments to provide a user experience that mirrors the ease of using a PaaS while giving the advantages of bare metal infrastructure.

Installation of Cuber

Before getting started, you need to install some prerequisites:

• Ruby
• Git
• Docker
• Pack
• kubectl

Once the prerequisites are set up, install Cuber by running the command:

gem install cuber

Quickstart Guide

To get started, follow these steps:

1. Open your application folder and create a Cuberfile. Here’s a sample:

ruby
# Give a name to your app
app myapp

# Get the code from this Git repository
repo . 

# Build the Docker image automatically (or provide a Dockerfile)
buildpacks herokubuildpacks:20

# Publish the Docker image in a registry
image username/myapp

# Connect to this Kubernetes cluster
kubeconfig path/to/kubeconfig.yml

# Run and scale any command on Kubernetes
proc :web, your_web_server_command

2. In your terminal, deploy your application by typing:

cuber deploy

3. Check on your application’s status with:

cuber info

Production-Ready Solution

Cuber has been instrumental in scaling Pushpad and has proven to be stable and reliable in production for over a year. Users have reported a remarkable 100% uptime and an impressive 80% savings on cloud costs.

Troubleshooting Your Cuber Experience

If you encounter any issues while using Cuber, consider the following ideas:

• Ensure that all your prerequisite installations were successful and that their paths are correctly configured.
• Validate your Cuberfile for syntax errors or misconfigurations.
• Check the Kubernetes cluster connectivity and that your kubeconfig.yml file is correctly set up.
• Consult the [Cuber documentation](https://cuber.cloud) for additional insights on configuration and troubleshooting techniques.
