Cluster Manage

Switch between Docker and Kubernetes backends for Kurtosis.

Check current cluster

kurtosis cluster get

Returns docker or kubernetes.

List available clusters

kurtosis cluster ls

Switch cluster

# Switch to Docker
kurtosis cluster set docker
 
# Switch to Kubernetes (uses current kubectl context)
kurtosis cluster set kubernetes

After switching, restart the engine:

kurtosis engine restart

Kubernetes setup

When using Kubernetes:

1. Ensure kubectl is configured and can reach your cluster:

``bash kubectl cluster-info kubectl get nodes ``

1. Switch Kurtosis to Kubernetes:

``bash kurtosis cluster set kubernetes kurtosis engine start ``

1. Start the gateway (required for local CLI to reach the k8s-based engine):

``bash kurtosis gateway & ``

1. Verify:

``bash kurtosis engine status ``

Config file

The cluster setting is stored in the Kurtosis config file:

kurtosis config path

Typically at ~/Library/Application Support/kurtosis/kurtosis-config.yml on macOS.
