This is the primary repository for
the Keptn software and documentation.
Keptn provides a “cloud-native” approach
for managing the application release lifecycle
metrics, observability, health checks,
with pre- and post-deployment evaluations and tasks.
It is an incubating project, under the umbrella of the
[Keptn Application Lifecycle working group](https://github.com/keptn/wg-app-lifecycle).

> **Note** Keptn was developed under the code name of
  "Keptn Lifecycle Toolkit" or "KLT" for short.
  The source code contains many vestiges of these names.

## Goals

Keptn provides Cloud Native teams with the following capabilities:

- Pre-requisite evaluation before deploying workloads and applications
- Checking the Application Health in a declarative (cloud-native) way
- Standardized way to run pre- and post-deployment tasks
- Provide out-of-the-box Observability
- Deployment lifecycle management

![Operator Maturity Model with third level circled in](https://raw.githubusercontent.com/keptn/lifecycle-toolkit/main/assets/operator-maturity.jpg)

Keptn can be seen as a general purpose and declarative
[Level 3 operator](https://operatorframework.io/operator-capabilities/)
for your Application.
For this reason, Keptn is agnostic to deployment tools
that are used and works with any GitOps solution.

For more information about the core concepts of Keptn, see
our core concepts
[documentation section](https://keptn.sh/stable/docs/core-concepts/).

## Status

Status of the different features:

- ![status](https://img.shields.io/badge/status-stable-brightgreen)
  Observability: expose [OTel](https://opentelemetry.io/) metrics and traces of your deployment.
- ![status](https://img.shields.io/badge/status-stable-brightgreen)
  K8s Custom Metrics: expose your Observability platform via the [Custom Metric API](https://github.com/kubernetes/design-proposals-archive/blob/main/instrumentation/custom-metrics-api.md).
- ![status](https://img.shields.io/badge/status-stable-brightgreen)
  Release lifecycle: handle pre- and post-checks of your Application deployment.
- ![status](https://img.shields.io/badge/status-stable-brightgreen)
  Certificate Manager: automatically configure TLS certificates with the
  [Keptn Certificate Manager](https://keptn.sh/stable/docs/components/certificate-operator/).
  You can instead
  [configure your own certificate manager](https://keptn.sh/stable/docs/installation/configuration/cert-manager/) to provide
  [secure communication with the Kube API](https://kubernetes.io/docs/concepts/security/controlling-access/#transport-security).

The status follows the
[Kubernetes API versioning schema](https://kubernetes.io/docs/reference/using-api/#api-versioning).

## Installation

Keptn can be installed on any Kubernetes cluster
running Kubernetes >=1.27.

Use the following command sequence
to install the latest release of Keptn:

```shell
helm repo add keptn https://charts.lifecycle.keptn.sh
helm repo update
helm upgrade --install keptn keptn/keptn -n keptn-system --create-namespace --wait
```

### Monitored namespaces

Keptn must be installed in its own namespace
that does not run other major components or deployments.

By default, the Keptn lifecycle orchestration
monitors all namespaces in the cluster
except for a few namespaces that are reserved
for specific Kubernetes and other components.
You can modify the Helm chart to specify the namespaces
where the Keptn lifecycle orchestration is allowed.
For more information, see the "Namespaces and Keptn" page in the
[Configuration](https://keptn.sh/stable/docs/installation/configuration/)
section of the documentation.
