Introduction to the Kubernetes Extension

The Steadybit Kubernetes Extension adds support for Chaos Engineering attacks and checks in your Kubernetes clusters. The extension works for local minikube environments and managed Kubernetes clusters, such as AWS EKS.

Integration and Functionality

The extension uses kubectl-commands and Kubernetes API calls to communicate with your cluster. The extension-container and extension-host are a good addition to support further attacks and checks in your Kubernetes cluster.

Installation of the Extension

If you've installed the Steadybit Agent in a Kubernetes cluster using our provided helm-chart, the Kubernetes extension is already installed by default.

Otherwise, you can also use the helm-chart of the Kubernetes extension to deploy the extension in your cluster.

Provided Pieces of Advice

See all

Image Pull Policy Set To Always

Ensure that your containers are always running the identical latest container image.

Image Version Explicitly Configured

Validates usage of explicit image versioning and avoids latest-tags.

Limit CPU Resources

Validates that your Kubernetes resources have a CPU limit configured.

Limit Ephemeral Storage Resources

Validates that your Kubernetes resources have a ephemeral storage limit configured.

Limit Memory Resources

Validates that your Kubernetes resources have a memory limit configured.

PodAntiAffinity Ensures Scheduling Pods on Different Nodes

Ensure multiple pods aren't deployed on the same cluster's node to increase availability in case one node becomes unavailable.

Probes Configured

Validates configuration of liveness and readiness probes.

Redundant Pod Deployment

Validate pod redundancy to have at least 2 pods per deployment

Requesting Reasonable CPU Resources

Validates that your Kubernetes resources request reasonable CPU.

Requesting Reasonable Ephemeral Storage Resources

Validates that your Kubernetes resources request reasonable ephemeral storage.

Requesting Reasonable Memory Resources

Validates that your Kubernetes resources request reasonable memory.

Rolling Update Deployments

Validates that you deploy Kubernetes resources via rolling updates.

Schedule Pods Across AWS Zones

Validate whether, right now, multiple pods of the same workload resource are deployed in the same AWS Availability Zone.

Schedule Pods Across Azure Zones

Validate whether, right now, multiple pods of the same workload resource are deployed in the same AWS Availability Zone.

Schedule Pods Across GCP Zones

Validate whether, right now, multiple pods of the same workload resource are deployed in the same AWS Availability Zone.
