Offline Installation

This document describes how to install Chaos Mesh in an offline environment.

Prerequisites

Before deploying Chaos Mesh, make sure the following items have been installed:

  • Kubernetes version >= 1.12
  • RBAC enabled (optional)
  • Docker

Prepare the installation file

To install Chaos Mesh offline, you need to get the installation images via an internet connection. Take the steps below:

  1. Specify the version you want to install:

    export CHAOS_MESH_VERSION="v1.1.0"

    Note:

    It is recommended that you use a stable release, or you can set the version to latest if you want to experience the latest features that are under development.

  2. Archive the docker images of Chaos Mesh:

    docker pull pingcap/chaos-mesh:${CHAOS_MESH_VERSION}
    docker pull pingcap/chaos-daemon:${CHAOS_MESH_VERSION}
    docker pull pingcap/chaos-dashboard:${CHAOS_MESH_VERSION}
    docker pull pingcap/coredns:v0.2.0
    docker save -o ./image-chaos-mesh pingcap/chaos-mesh:${CHAOS_MESH_VERSION}
    docker save -o ./image-chaos-daemon pingcap/chaos-daemon:${CHAOS_MESH_VERSION}
    docker save -o ./image-chaos-dashboard pingcap/chaos-dashboard:${CHAOS_MESH_VERSION}
    docker save -o ./image-chaos-coredns pingcap/coredns:v0.2.0
  3. Download the Chaos Mesh repository to your local:

    wget "https://github.com/chaos-mesh/chaos-mesh/archive/${CHAOS_MESH_VERSION}.zip"

    Or you can download the latest unstable version:

    wget https://github.com/chaos-mesh/chaos-mesh/archive/master.zip
  4. Copy the ./image-chaos-mesh, ./image-chaos-daemon, ./image-chaos-dashboard, and {CHAOS_MESH_VERSION}.zip into the offline environment.

Install Chaos Mesh offline

Now that you already have the image and repo archive files in the offline environment, start installing Chaos Mesh.

  1. Specify the version you are going to install in the offline environment:

    export CHAOS_MESH_VERSION="v1.1.0"
  2. Load the image from the archive files:

    docker load -i ./image-chaos-mesh
    docker load -i ./image-chaos-daemon
    docker load -i ./image-chaos-dashboard
    docker load -i ./image-chaos-coredns
  3. Push the Chaos Mesh images. You can choose to push them to Docker Registry or Docker Hub.

    • Push images to Docker Registry

      a. Set the Docker Registry variable, for example:

      export DOCKER_REGISTRY=localhost:5000

      b. Tag these images with $DOCKER_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}
      export CHAOS_COREDNS_IMAGE=$DOCKER_REGISTRY/pingcap/coredns:v0.2.0
      docker image tag pingcap/chaos-mesh:${CHAOS_MESH_VERSION} $CHAOS_MESH_IMAGE
      docker image tag pingcap/chaos-daemon:${CHAOS_MESH_VERSION} $CHAOS_DAEMON_IMAGE
      docker image tag pingcap/chaos-dashboard:${CHAOS_MESH_VERSION} $CHAOS_DASHBOARD_IMAGE
      docker image tag pingcap/coredns:v0.2.0 $CHAOS_COREDNS_IMAGE

      c. Push these images to Docker Registry:

      docker push $CHAOS_MESH_IMAGE
      docker push $CHAOS_DAEMON_IMAGE
      docker push $CHAOS_DASHBOARD_IMAGE
      docker push $CHAOS_COREDNS_IMAGE

      Note:

      If the Docker Registry can only work locally, you need to load and push these images on each K8s node.

    • Push images to Docker Hub

      a. Set the Docker Hub variable, for example:

      export DOCKER_HUB=hub

      b. Tag these images with $DOCKER_REGISTRY:

      export CHAOS_MESH_IMAGE=$DOCKER_HUB/chaos-mesh:${CHAOS_MESH_VERSION}
      export CHAOS_DAEMON_IMAGE=$DOCKER_HUB/chaos-daemon:${CHAOS_MESH_VERSION}
      export CHAOS_DASHBOARD_IMAGE=$DOCKER_HUB/chaos-dashboard:${CHAOS_MESH_VERSION}
      export CHAOS_COREDNS_IMAGE=$DOCKER_HUB/coredns:v0.2.0
      docker image tag pingcap/chaos-mesh:${CHAOS_MESH_VERSION} $CHAOS_MESH_IMAGE
      docker image tag pingcap/chaos-daemon:${CHAOS_MESH_VERSION} $CHAOS_DAEMON_IMAGE
      docker image tag pingcap/chaos-dashboard:${CHAOS_MESH_VERSION} $CHAOS_DASHBOARD_IMAGE
      docker image tag pingcap/coredns:v0.2.0 $CHAOS_COREDNS_IMAGE

      c. Push these images to Docker Registry:

      docker push $CHAOS_MESH_IMAGE
      docker push $CHAOS_DAEMON_IMAGE
      docker push $CHAOS_DASHBOARD_IMAGE
      docker push $CHAOS_COREDNS_IMAGE
  4. Install Chaos Mesh offline with the following steps:

    a. Unzip the repo archive files to a path:

    unzip ${CHAOS_MESH_VERSION}.zip -d chaos-mesh && cd chaos-mesh/*/

    b. Create a namespace for installing Chaos Mesh:

    kubectl create namespace chaos-testing

    c. Install Chaos Mesh by helm:

    d. Check whether Chaos Mesh pods are installed:

    kubectl get pods --namespace chaos-testing -l app.kubernetes.io/instance=chaos-mesh

    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

    After executing the above commands, you should be able to see the output indicating that all Chaos Mesh pods are up and running. Otherwise, check the current environment according to the prompt message or create an issue for help.
