What is the Keptn Lifecycle Toolkit?

In today's fast-paced world of software development, deploying and maintaining applications is becoming increasingly complex. This is where Keptn Lifecycle Toolkit comes into the picture. It is an open-source project that aims to simplify the deployment, scaling, and monitoring of cloud-native applications.

In this article, we will explain what the Keptn Lifecycle Toolkit is and how it can help you streamline your application delivery process.

Introduction to Keptn Lifecycle Toolkit?

The Keptn Lifecycle Toolkit is an open-source project that provides an end-to-end workflow for the delivery and operation of cloud-native applications. It allows developers and operations teams to automate the deployment, testing, and monitoring of their applications across different environments.

The toolkit is built on top of Kubernetes, a popular container orchestration platform. It is designed to be vendor-agnostic, which means it can work with any cloud provider or infrastructure platform.

Keptn is also extensible, allowing users to add custom integrations and workflows to suit their specific requirements.

How does the Keptn Lifecycle Toolkit work?

The Keptn Lifecycle Toolkit follows a four-step workflow to manage the application delivery process. These steps include:

1. Onboarding: This step involves registering an application with Keptn and defining its deployment and testing requirements.

2. Deployment: Once the application is onboarded, Keptn automatically deploys it to the target environment, such as a Kubernetes cluster.

3. Testing: Keptn runs automated tests to ensure that the application is functioning correctly in the target environment.

4. Remediation: If any issues are found during testing, Keptn can automatically remediate them by rolling back the deployment or taking other actions.

Commands to install Keptn Lifecycle Toolkit

The Keptn Lifecycle Toolkit can be installed using the following commands:

1. Install the Keptn CLI:

curl -sL https://get.keptn.sh | sudo -E bash

2. Install the Keptn CLI plugins:

keptn install --platform=kubernetes

3. Verify the installation:

keptn status

Once Keptn is installed, you can start onboarding your applications and defining their deployment and testing requirements.

Examples of using Keptn Lifecycle Toolkit

1. Onboarding an application:

keptn onboard service carts --project=sockshop --chart=charts/carts

2. Defining deployment and testing requirements:

keptn add-resource --project=sockshop --stage=dev --service=carts --resource=jmeter/basic_check.jmx --resourceUri=jmeter/basic_check.jmx

3. Deploying an application:

keptn send event new-artifact --project=sockshop --service=carts --image=docker.io/keptnexamples/carts --tag=0.12.1

The Keptn Lifecycle Toolkit is an open-source project that provides an end-to-end workflow for the delivery and operation of cloud-native applications. It simplifies the deployment, scaling, and monitoring of applications, making it easier for developers and operations teams to manage their applications in different environments.
