This script is used to install chaos-mesh.
Before running this script, please ensure that:
* have installed docker if you run chaos-mesh in local.
* have installed Kubernetes if you run chaos-mesh in normal Kubernetes cluster
USAGE:
install.sh [FLAGS] [OPTIONS]
FLAGS:
-h, --help Prints help information
-d, --dependency-only Install dependencies only, including kind, kubectl, local-kube.
--force Force reinstall all components if they are already installed, include: kind, local-kube, chaos-mesh
--force-chaos-mesh Force reinstall chaos-mesh if it is already installed
--force-local-kube Force reinstall local Kubernetes cluster if it is already installed
--force-kubectl Force reinstall kubectl client if it is already installed
--force-kind Force reinstall Kind if it is already installed
--docker-mirror Use docker mirror to pull image, dockerhub.azk8s.cn => docker.io, gcr.azk8s.cn => gcr.io
--volume-provisioner Deploy volume provisioner in local Kubernetes cluster
--local-registry Deploy local docker registry in local Kubernetes cluster
--template Locally render templates
--k3s Install chaos-mesh in k3s environment
--microk8s Install chaos-mesh in microk8s environment
--host-network Install chaos-mesh using hostNetwork
OPTIONS:
-v, --version Version of chaos-mesh, default value: latest
-l, --local [kind] Choose a way to run a local kubernetes cluster, supported value: kind,
If this value is not set and the Kubernetes is not installed, this script will exit with 1.
-n, --name Name of Kubernetes cluster, default value: kind
-c --crd The path of the crd files. Get the crd file from "https://mirrors.chaos-mesh.org" if the crd path is empty.
-r --runtime Runtime specifies which container runtime to use. Currently we only supports docker and containerd. default value: docker
--kind-version Version of the Kind tool, default value: v0.7.0
--node-num The count of the cluster nodes,default value: 3
--k8s-version Version of the Kubernetes cluster,default value: v1.17.2
--volume-num The volumes number of each kubernetes node,default value: 5
--release-name Release name of chaos-mesh, default value: chaos-mesh
--namespace Namespace of chaos-mesh, default value: chaos-testing
--timezone Specifies timezone to be used by chaos-dashboard, chaos-daemon and controlller.
