Install Chaos Mesh Offline

This document describes how to install Chaos Mesh offline.


Before installing Chaos Mesh, make sure that Docker is installed and the Kubernetes cluster is deployed in the offline environment. If the environment is not prepared, refer to the following documents to install Docker and deploy the Kubernetes cluster:

Prepare installation files#

Before you install Chaos Mesh offline, you need to download all Chaos Mesh images and repository compression packages from the machines with external network connection, and then copy the downloaded files into your offline environment.

Specify version number#

Set the version number of Chaos Mesh as the environment variable on the machine with external network connection:

Download Chaos Mesh images#

On the machine connected to external network, pull images using the version number that has been set:

docker pull pingcap/chaos-mesh:${CHAOS_MESH_VERSION}docker pull pingcap/chaos-daemon:${CHAOS_MESH_VERSION}docker pull pingcap/chaos-dashboard:${CHAOS_MESH_VERSION}

Save images as the tar packages:

docker save pingcap/chaos-mesh:${CHAOS_MESH_VERSION} > image-chaos-mesh.tardocker save pingcap/chaos-daemon:${CHAOS_MESH_VERSION} > image-chaos-daemon.tardocker save pingcap/chaos-dashboard:${CHAOS_MESH_VERSION} > image-chaos-dashboard.tar

To simulate a DNS fault (for example, make the DNS responses return a random wrong IP address), you need to pull the additional pingcap/coredns images.

Download the repository compression package of Chaos Mesh#

On the machine connected to the external network, download the zip package of Chaos Mesh:

curl${CHAOS_MESH_VERSION}.zip -o

The latest version corresponds to the master branch of the Chaos Mesh repository. The download link of the latest zip package is as follows:

Copy files#

After downloading all the files required for installation, you need to copy these files to the offline environment:

  • image-chaos-mesh.tar
  • image-chaos-daemon.tar
  • image-chaos-dashboard.tar

Install Chaos Mesh#

After copying the tar package of the Chaos Mesh images and the zip package of the repository to the offline environment, take the following steps to install Chaos Mesh.

Step 1: Load Chaos Mesh images#

Load images from the tar package:

docker load < image-chaos-mesh.tardocker load < image-chaos-daemon.tardocker load < image-chaos-dashboard.tar

Step 2: Push images to Registry#


Before pushing images to Registry, make sure that Registry has been deployed in the offline environment. If Registry is not deployed, refer to Docker Registry for the deployment method.

Set the Chaos Mesh version and the Registry address as the environment variable:

Mark the images so that the images point to the Registry:

export CHAOS_MESH_IMAGE=$DOCKER_REGISTRY/pingcap/chaos-mesh:${CHAOS_MESH_VERSION}export CHAOS_DAEMON_IMAGE=$DOCKER_REGISTRY/pingcap/chaos-daemon:${CHAOS_MESH_VERSION}export CHAOS_DASHBOARD_IMAGE=$DOCKER_REGISTRY/pingcap/chaos-dashboard:${CHAOS_MESH_VERSION}docker image tag pingcap/chaos-mesh:${CHAOS_MESH_VERSION} $CHAOS_MESH_IMAGEdocker image tag pingcap/chaos-daemon:${CHAOS_MESH_VERSION} $CHAOS_DAEMON_IMAGEdocker image tag pingcap/chaos-dashboard:${CHAOS_MESH_VERSION} $CHAOS_DASHBOARD_IMAGE

Push images to Registry:


Step 3: Install Chaos Mesh using Helm#

Unpack the zip package of Chaos Mesh:

unzip -d chaos-mesh && cd chaos-mesh

Create the namespace:

kubectl create ns chaos-testing

Execute the installation command. When executing the installation command, you need to specify the namespace of Chaos Mesh and the image value of each component:

Verify the installation#

To check the running status of Chaos Mesh, execute the following command:

kubectl get po -n chaos-testing

The expected output is as follows:

NAME                                        READY   STATUS    RESTARTS   AGEchaos-controller-manager-69fd5c46c8-xlqpc   1/1     Running   0          2d5hchaos-daemon-jb8xh                          1/1     Running   0          2d5hchaos-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 examplekubectl describe po -n chaos-testing chaos-controller-manager-69fd5c46c8-xlqpc

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.
