About this project

Deployah bridges the gap between complex Helm charts and resource-heavy cluster-side setups. Designed for simplicity, this CLI lets users turn a brief application specification into a live Helm release on Kubernetes without requiring extensive Helm knowledge or cluster-side configuration. Streamline app deployments effortlessly.

Deployah is an innovative command-line interface (CLI) designed to streamline the deployment of applications to Kubernetes without requiring extensive knowledge of Helm, Kubernetes, or complex cluster setups. With Deployah, users can easily convert a concise application specification into a fully functioning Helm release, simplifying the deployment process to just one binary.

Key Features

Ease of Use: Employs a straightforward Spec-to-Release approach, similar to the Source-to-Image (S2I) methodology, but specifically for deploying applications. Just define a short YAML spec and Deployah manages the rest.
Single Binary: No need to install additional tools such as helm, kubectl, or kind. Deployah includes these as libraries, significantly reducing setup complexity and the potential for configuration conflicts.
Fast Deployment: Create and deploy applications quickly using a simple command workflow that is effective for both local and remote Kubernetes clusters.

How It Works

Deployah operates in a systematic three-phase process:

Read the Spec: It begins by parsing the provided YAML specification, validating the input, and ensuring that configuration errors are caught early.
Resolve Configuration: The tool selects the appropriate environment, applies any specified variables, and fills in sensible defaults for deployment.
Deploy: Finally, Deployah generates Helm values from the spec and installs the Helm release on the designated Kubernetes cluster. Users do not have to manually write Helm charts, enabling faster and more efficient application deployment.

Example Usage

To get started, simply:

Start a Local Cluster:
```
deployah cluster up
```

Create an Application Spec in a deployah.yaml file:

apiVersion: v1-alpha.2
project: my-first-app
components:
  web:
    image: nginx:latest
    port: 80
    environments: [local]
    expose: true

Deploy the Application:
```
deployah deploy local
```
Check Status:
```
deployah status my-first-app
```

Benefits

Perfect for developers who want to deploy applications quickly without deep Kubernetes expertise.
Simplifies the process significantly with no need for prior Helm knowledge or complex local setup procedures.
Improves productivity by minimizing the learning curve and enhancing deployment efficiency.

Deployah is ideal for teams looking to accelerate application deployment in Kubernetes, ensuring a seamless integration experience without heavy lifting.
