KubeKarma

What is KubeKarma?

KubeKarma is a tool for continuous testing of Kubernetes applications. Currently, KubeKarma supports the following types of tests:

NetworkTestSuite

• NetworkTestSuite

Application Acceptance Continuous Test (AACT)

I define this test as an Application Acceptance Continuous Test (AACT).

The test's main point of view is the application itself; it tests if the application has the correct configuration in the platform to run correctly. As the infrastructure can change eventually, the execution of the test periodically ensures that the application can still run correctly.

For instance, the network policies of the Kubernetes infrastructure can change, and the application can be affected. Still, not only because of the NetworkPolicies but also because of the underlying layers of the networks (VPC, Subnets, Firewall rules, Security Groups, etc.).

Benefits of AACT

• Increased Confidence: It provides greater confidence that the application will run smoothly at any time, even after changes to the infrastructure.
• Early Problem Detection: It enables early detection of configuration or compatibility issues that could impact the application's performance.
• Facilitated Troubleshooting: AACT aids in Troubleshooting by providing a baseline of expected behaviour for the application within its environment. When issues or anomalies arise, it becomes easier to pinpoint the root causes because the continuous testing process establishes a clear understanding of how the application should operate under normal circumstances.

Tech Stack behind KubeKarma

• Kubernetes
• Skaffold
• Minikube
• Docker
• Python

Usage

Helm must be installed to use the charts. Please refer to Helm's documentation to get started.

Once Helm has been set up correctly, add the repo as follows:

  helm repo add kubekarma-repo https://cristiansteib.github.io/kubekarma/

If you had already added this repo earlier, run helm repo update to retrieve the latest versions of the packages. You can then run helm search repo kubekarma to see the charts.

To install the kubekarma operator chart:

    helm install kubekarma kubekarma-repo/kubekarma

To uninstall the chart:

    helm delete kubekarma

Development

minikube profile custom
minikube start -p custom
skaffold dev --port-forward
