在k8s里面安装ChaosMesh比较简单，请参考《混沌工程之ChaosMesh使用之一模拟CPU使用率》。

但是如果你想自己改点啥，加点功能，那就得从源码开始编译安装。

本篇就带你来看下如何实现编译安装。

环境
操作系统：macOS 11.1
golang 1.15.7
安装依赖

brew install golang nodejs yarn kind

安装 Docker 和 Docker Registry。

brew install --cask docker

docker run -d -p 5000:5000 --name registry registry:2.7.1

添加环境变量

echo 'export DOCKER_REGISTRY=localhost:5000' >> ~/.bash_profile
echo 'export PATH=$(go env GOPATH)/bin:${PATH}' >> ~/.bash_profile
source ~/.bash_profile

构建

git clone https://github.com/chaos-mesh/chaos-mesh.git && cd chaos-mesh
git clone -b v2.0.0-beta.2 https://github.com/chaos-mesh/chaos-mesh.git v2.0.0-beta.2

如果不构建UI，则访问界面会提示：

加载镜像到 kind

kind load docker-image localhost:5000/pingcap/chaos-mesh:latest
kind load docker-image localhost:5000/pingcap/chaos-daemon:latest
kind load docker-image localhost:5000/pingcap/chaos-dashboard:latest

修改 helm/chaos-mesh/values.yaml

替换 chaos-mesh，chaos-daemon，chaos-dashboard 镜像

修改 chaos-dashboard 端口：

部署

helm install chaos-mesh helm/chaos-mesh --namespace=chaos-testing --set chaosDaemon.runtime=containerd --set chaosDaemon.socketPath=/run/containerd/containerd.sock

检查

kubectl get pod,svc -n chaos-testing

更新

helm upgrade chaos-mesh helm/chaos-mesh --namespace=chaos-testing
