混沌工具之 ChaosMesh 源码编译安装
【摘要】 ChaosMesh 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。
ChaosMesh 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。
环境要求：
- 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
拉取源码：
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-b

Creating cluster "kind" ...
✓ Ensuring node image (kindest/node:v1.20.2) 🖼 ^[[B^[[B
✓ Preparing nodes 📦 📦 📦 📦
✓ Writing configuration 📜
✓ Starting control-plane 🕹️
✓ Installing CNI 🔌
✓ Installing StorageClass 💾
✓ Joining worker nodes 🚜
Set kubectl context to "kind-kind"
You can now use your cluster with:
kubectl cluster-info --context kind-kind
Not sure what to do next? 😅 Check out https://kind.sigs.k8s.io/docs/user/quick-start/

构建新镜像
# 只使用 make 不构建 chaos-dashboard
make
# 同时构建 chaos-dashboard

# make docker-push # 推送到镜像仓库，目前本机操作不用。如果用阿里云镜像服务，可以修改Makefile。

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：
helm 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
