## CRD开发(API)
|
|
|
|
|
|
|
|
|
|
1. 编辑CRD
|
|
|
|
|
```sh
|
|
|
|
|
make manifests
|
|
|
|
|
make generate
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
2. 安装
|
|
|
|
|
```sh
|
|
|
|
|
make install
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
3. 编辑样例
|
|
|
|
|
```yaml
|
|
|
|
|
apiVersion: devops.go17/v1beta1
|
|
|
|
|
kind: AccessBinding
|
|
|
|
|
metadata:
|
|
|
|
|
labels:
|
|
|
|
|
app.kubernetes.io/name: operator
|
|
|
|
|
app.kubernetes.io/managed-by: kustomize
|
|
|
|
|
name: accessbinding-sample
|
|
|
|
|
spec:
|
|
|
|
|
namespace: 'default'
|
|
|
|
|
deployment: 'nginx-test'
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
4. 验证
|
|
|
|
|
```sh
|
|
|
|
|
kubectl apply -f config/samples/devops_v1beta1_accessbinding.yaml
|
|
|
|
|
kubectl get AccessBinding
|
|
|
|
|
kubectl delete AccessBinding accessbinding-sample
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
