0.1 环境
博主的机器Mac amd64 arm用户需要去看安装Kubebuilder需要先看kubebuilder官方文档的Quick Start部分。
0.2 什么是kubebuilder
暂时省略以后会写一篇专门的博客分析。
1. 安装Kubebuilder
1.1 需要预先准备好的环境
需要go环境dockerminikubekind也行用来创建集群。如果没有可以自行安装不过一般到了kubebuilder学习了kubernetes应该有一定了解了所以上述环境大概率是有的。
注意这里我使用的集群环境是minikube。
1.2 安装kubebuilder kustomize
brew install kubebuilder
brew install kustomize2. 项目初始化
2.1 新建并进入文件夹
mkdir Helo
cd Helo2.2 kubebuilder初始化
kubebuilder init --domain xxx.domain --repo Helo--domain xxx.domain是我们的项目域名--repo Helo是仓库地址。
如果初始化成功将会看到如下提示可以进行kubebuilder create api操作了

Get controller runtime:
$ go get sigs.k8s.io/controller-runtimev0.14.1
Update dependencies:
$ go mod tidy
Next: define a resource with:
$ kubebuilder create api使用tree命令先看一下当前目录情况⬇️

命令行执行创建Api命令其中名称可以自己设置
API Group 是相关 API 功能的集合每个 Group 拥有一或多个 Versions GV每个 GV 都包含 N 个 api 类型称之为 Kinds不同 Version 同一个 Kinds 可能不同
kubebuilder create api --group apps --version v1 --kind Test如果创建成功将会看到如下所示的提示⬇️让我们生成manifests
kubebuilder create api --group apps --version v1 --kind Test

$ make generate

Next: implement your new API and generate the manifests (e.g. CRDs,CRs) with:
$ make manifests此外执行tree命令后可以发现创建api后目录结构也发生了变化。需要注意的变化是生成了⬇️

└── main.go14 directories, 37 files4. 解决端口占用问题如果没有可以跳过
首先使用go run ./main.go测试一下端口占用问题我这里可以看到报错信息error listening on :8080: listen tcp :8080: bind: address already in use
go run ./main.go
2023-04-17T10:22:0108:00 INFO controller-runtime.metrics Metrics server is starting to listen {addr: :8080}
2023-04-17T10:22:0108:00 ERROR controller-runtime.metrics metrics server failed to listen. You may want to disable the metrics server or use another port if it is due to conflicts {error: error listening on :8080: listen tcp :8080: bind: address already in use}

runtime.main/usr/local/Cellar/go/1.20.3/libexec/src/runtime/proc.go:250
exit status 1通过lsof 命令查看端口占用可以看到是main其实是另一个kubebuilder实例。
lsof -i:8080
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
main 4304 levi 7u IPv6 0xc681612e5637de5 0t0 TCP *:http-alt (LISTEN)这里我并不想杀掉原来的进程释放8080因此将代码中默认的8080改为8182通过lsof事先找到一个没有被占用的端口即可。
需要修改的地方为
1main.go中将metrics-bind-address替换从8080替换为8280。 flag.StringVar(metricsAddr, metrics-bind-address, :8080, The address the metric endpoint binds to.)2Helo/config/default/manager_auth_proxy_patch.yaml中upstream和--metrics-bind-address同样需要替换成8280。 - --upstreamhttp://127.0.0.1:8080/- --metrics-bind-address127.0.0.1:8080如果8081被占用同理进行修改我这里是将8081替换成了8281。
搞定端口占用问题后进入下面步骤即可。
5. 安装CRD
5.1 进入集群
输入minikube update-context命令
# 创建集群
minikube start# 进入集群
minikube update-context## 看到的输出结果为 minikube context has been updated to point to 127.0.0.1:50336 当前的上下文为 minikube5.2 在集群中安装CRD
# 将CRD安装到集群中 (首先要进入minikube上下文)
make install
# 运行
make run
# 运行结果参考
test -s /Users/levi/wrksp/Helo/bin/controller-gen /Users/levi/wrksp/Helo/bin/controller-gen --version | grep -q v0.11.1 || \GOBIN/Users/levi/wrksp/Helo/bin go install sigs.k8s.io/controller-tools/cmd/controller-genv0.11.1

go fmt ./...
go vet ./...
go run ./main.go
2023-04-17T15:11:5208:00 INFO controller-runtime.metrics Metrics server is starting to listen {addr: :8280}
2023-04-17T15:11:5208:00 INFO setup starting manager
2023-04-17T15:11:5208:00 INFO Starting server {path: /metrics, kind: metrics, addr: [::]:8280}
2023-04-17T15:11:5208:00 INFO Starting server {kind: health probe, addr: [::]:8281}
2023-04-17T15:11:5208:00 INFO Starting EventSource {controller: test, controllerGroup: apps.xxx.domain, controllerKind: Test, source: kind source: *v1.Test}

2023-04-17T15:11:5208:00 INFO Starting workers {controller: test, controllerGroup: apps.xxx.domain, controllerKind: Test, worker count: 1}
需要注意controller是一直运行的ctrl c 将会导致controller退出。
6. 创建资源实例
6.1 到目前为止的总结
前面的内容是创建了自定义的资源Test 类型的CRD接下来我们将自定义资源实例化创建该类型的pod。
CRD安装后kubebuilder已经自动帮我们生成了该类型的部署文件样例位于./config/samples/apps_v1_test.yaml文件中。
内容为
apiVersion: apps.xxx.domain/v1
kind: Test
metadata:labels:app.kubernetes.io/name: testapp.kubernetes.io/instance: test-sampleapp.kubernetes.io/part-of: heloapp.kubernetes.io/managed-by: kustomizeapp.kubernetes.io/created-by: heloname: test-sample
spec:# TODO(user): Add fields here6.2 创建实例
打开新的terminalcd Helo登陆集群minikube update-context创建实例
kubectl apply -f config/samples/
## 创建成功输出
test.apps.xxx.domain/test-sample created查看Test类型自定义资源的实例test-sample
# 查看Test资源实例
kubectl get Test## 查看Test资源实例的输出
NAME AGE
test-sample 15s6.3 修改实例内容
kubectl edit Test test-sample我的修改是在最下面添加了注意缩进。
spec:foo: bar可以看到的结果为
test.apps.xxx.domain/test-sample edited7. 删除实例关闭controller
删除实例
kubectl delete -f config/samples/## 删除结果
test.apps.xxx.domain test-sample deleted关闭controllerctrl c即可。 卸载controllermake uninstall——没必要删除先留着后面做实验还用。
8. 镜像制作 部署
注意这里主要是参考了《kubebuilder实战之二初次体验kubebuilder》
前面的controller是运行在k8s之外的生产环境中controller一般运行在k8s的环境内。以下操作均在目录./Helo/中进行
8.1 镜像制作
