Keptn

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.

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

Keptn can be seen as a general purpose and declarative Level 3 operator 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.

Status

Status of the different features:

• Observability: expose OTel metrics and traces of your deployment.
• K8s Custom Metrics: expose your Observability platform via the Custom Metric API.
• Release lifecycle: handle pre- and post-checks of your Application deployment.
• Certificate Manager: automatically configure TLS certificates with the Keptn Certificate Manager. You can instead configure your own certificate manager to provide secure communication with the Kube API.

The status follows the Kubernetes API versioning schema.

• Members and Charter: Describes the formation and responsibilities of the Keptn Governance Committee, including its scope, members, and core responsibilities.

Installation

Keptn can be installed on any Kubernetes cluster running Kubernetes >=1.24.

For users running vCluster, please note that you may need to modify your configuration before installing Keptn; see Running Keptn with vCluster for more information.

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

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 section of the documentation.
