Quick Start
This document describes how to start Chaos Mesh quickly in a test or local environment.
In this document, Chaos Mesh is installed via a script for quick trial only.
If you need to install Chaos Mesh in the production environment or other strict non-test scenarios, it is recommended to use Helm. For more details, refer to Installation using Helm.
Environment preparation
Please ensure that the Kubernetes cluster is deployed in the environment before the trial. If the Kubernetes cluster has not been deployed, you can refer to the links below to complete the deployment:
Quick installation
To install Chaos Mesh in a test environment, run the following script:
- K8s
- kind
- K3s
- MicroK8s
If you want to specify a kind
version, add the --kind-version xx
parameter at the end of the script, for example:
After running, Chaos Mesh will automatically install the appropriate version of CustomResourceDefinitions and the required components.
For more installation details, refer to the source code of the install.sh
.
Verify the installation
To check the running status of Chaos Mesh, execute the following command:
kubectl get po -n chaos-mesh
The expected output is as follows:
NAME READY STATUS RESTARTS AGE
chaos-controller-manager-69fd5c46c8-xlqpc 3/3 Running 0 2d5h
chaos-daemon-jb8xh 1/1 Running 0 2d5h
chaos-dashboard-98c4c5f97-tx5ds 1/1 Running 0 2d5h
If your actual output is similar to the expected output with NAME
, READY
, STATUS
, RESTARTS
, and AGE
, it means that Helm is installed successfully.
If the STATUS
of your actual output is not Running
, then execute the following command to check the Pod details, and troubleshoot issues according to the error information.
# Take the chaos-controller as an example
kubectl describe po -n chaos-mesh chaos-controller-manager-69fd5c46c8-xlqpc
If leader-election
feature is turned off manually, chaos-controller-manager
should only have 1 replication.
NAME READY STATUS RESTARTS AGE
chaos-controller-manager-69fd5c46c8-xlqpc 1/1 Running 0 2d5h
chaos-daemon-jb8xh 1/1 Running 0 2d5h
chaos-dashboard-98c4c5f97-tx5ds 1/1 Running 0 2d5h
Run Chaos experiments
After verifying that the installation is complete, you can run a Chaos experiment to experience the features of Chaos Mesh.
For the method to run the experiment, it is recommended to refer to Run a Chaos experiment. After successfully creating the experiment, you can observe the running status of the experiment on the Chaos Dashboard.
Uninstall Chaos Mesh
To uninstall Chaos Mesh, execute the following command:
You can also delete the chaos-mesh
namespace to directly uninstall Chaos Mesh:
kubectl delete ns chaos-mesh
FAQ
Why the local
directory appears in the root directory after installation?
If you don't install kind
in the existing environment, and you use the --local kind
parameter when executing the installation command, the install.sh
script will automatically install the kind
in the local
directory under the root directory.
