一个Kubebuilder的简单demo

1# download kubebuilder and install locally.
2curl -L -o kubebuilder https://go.kubebuilder.io/dl/latest/$(go env GOOS)/$(go env GOARCH)
3chmod +x kubebuilder && mv kubebuilder /usr/local/bin/
4# 查看是否安装成功
5kubebuilder version

 1# kubebuilder autocompletion
 2echo 'source <(kubebuilder completion bash)' >>~/.bash_profile
 3source ~/.bash_profile
 4kubebuilder completion bash >/opt/homebrew/etc/bash_completion.d/kubebuilder

 6# 增加kb简写自动补全
 7vim ~/.bash_profile
 8alias kb=kubebuilder
 9complete -o default -F __start_kubebuilder kb
10source ~/.bash_profile

 1# 初始化项目
 2kubebuilder init --domain github.com --repo github.com/kubebuilder-demo/simple
 3
 4# 创建api
 5kubebuilder create api --group kubebuilder-demo --version v1 --kind Simple
 6# 生成crd
 7make manifests
 8# 安装crd到k8s集群,这里用于kustomize，如果没有会自动下载到./bin/，这里下载kustomize可能被qiang自己想办法
 9make install
10# 查看crd是否安装成功：simples.kubebuilder-demo.github.com
11kubectl get crd
12
13# 启动controller
14make run
15
16# 部署cr
17kubectl apply -f config/samples/kubebuilder-demo_v1_simple.yaml
18# 查看simple的cr是否部署成功
19kubectl get simple
20
21# 打包docker镜像
22# 这里发现 Dockerfile 里的 gcr.io/distroless/static:nonroot 镜像被qiang了，改为：devk8s/gcr-io_distroless_static:nonroot
23# Dockerfile golang builder 时要加 ENV GOPROXY="https://goproxy.cn,direct" 
24# 用docker-build时，k8s机器上报standard_init_linux.go:228: exec user process caused: exec format error，平台不兼容导致所以用docker-buildx
25make docker-buildx IMG=kubebuilderdemo/simple:0.0.1
26
27# 部署到k8s集群
28# config/default/manager_auth_proxy_patch.yaml下的 
29# gcr.io/kubebuilder/kube-rbac-proxy:v0.13.1 改为 devk8s/gcr-io_kubebuilder_kube-rbac-proxy:v0.13.1
30make deploy IMG=kubebuilderdemo/simple:0.0.1
31# 查看资源是否就绪
32kubectl -nsimple-system get svc
33kubectl -nsimple-system get deploy
34kubectl -nsimple-system get pod
35
36# pod启动不了的几个调试命令
37 kubectl -nsimple-system describe pod pod名称
38 kubectl -nsimple-system logs  pod名称 --all-containers
39 kubectl -nsimple-system logs pod名称 -c 容器名称
40 kubectl -nsimple-system get event
41 kubectl -nsimple-system get events --field-selector involvedObject.name=pod名称

43# 卸载crd
44make uninstall
45# 反部署
