Get started on Minikube

This document describes how to deploy Chaos Mesh in Kubernetes on your laptop (Linux or macOS) using Minikube.

Prerequisites

Before deployment, make sure Minikube is installed on your local machine.

Step 1: Set up the Kubernetes environment

Perform the following steps to set up the local Kubernetes environment:

1. Start a Kubernetes cluster:

   minikube start --kubernetes-version v1.15.0 --cpus 4 --memory "8192mb"

   Note:

   It is recommended to allocate enough RAM (more than 8192 MiB) to the Virtual Machine (VM) using the --cpus and --memory flag.

2. Install helm:

   curl https://raw.githubusercontent.com/helm/helm/master/scripts/get | bash
   helm init

3. Check whether the helm tiller pod is running:

   kubectl -n kube-system get pods -l app=helm

Step 2: Install Chaos Mesh

The above command installs all the CRDs, required service account configuration, and all components. Before you start running a chaos experiment, verify if Chaos Mesh is installed correctly.

You also can use helm to install Chaos Mesh manually.

Verify your installation

Verify if Chaos Mesh is running

kubectl get pod -n chaos-testing

Expected output:

NAME                                        READY   STATUS    RESTARTS   AGE
chaos-controller-manager-6d6d95cd94-kl8gs   1/1     Running   0          3m40s
chaos-daemon-5shkv                          1/1     Running   0          3m40s
chaos-dashboard-d998856f6-vgrjs             1/1     Running   0          3m40s

Uninstallation

You can uninstall Chaos Mesh by deleting the namespace.

Limitations

There are some known restrictions for Chaos Operator deployed in the Minikube cluster:

• netem chaos is only supported for Minikube clusters >= version 1.6.

In Minikube, the default virtual machine driver's image does not contain the sch_netem kernel module in earlier versions. You can use none driver (if your host is Linux with the sch_netem kernel module loaded) to try these chaos actions using Minikube or build an image with sch_netem by yourself.
