我試圖解析一個 yaml 文件并只更新一個屬性，問題是類型是RAW，當(dāng)我更新一個字段時它會更新整個對象，我想要的是僅更新 NatIPNamesfromtest1到test2，但不更改(10000)的值minPortsPerVM我該怎么做？這是山藥apiVersion: core.gardener.cloud/v1beta1kind: Shootmetadata: name: test namespace: nsspec: provider: type: aaa infrastructureConfig: apiVersion: gcp.provider.extensions.gardener.cloud/v1alpha1 kind: InfrastructureConfig networks: cloudNAT: minPortsPerVM: 10000 natIPNames: - name: test1這是代碼package mainimport ( "encoding/json" "fmt" gcpv1alpha1 "github.com/gardener/gardener-extension-provider-gcp/pkg/apis/gcp/v1alpha1" "github.com/gardener/gardener/pkg/apis/core/v1beta1" "io/ioutil" "k8s.io/apimachinery/pkg/runtime" "k8s.io/apimachinery/pkg/util/yaml")func main() { shoot, e := parseShoot("test.yaml") if e != nil { fmt.Println(e) } shoot.Spec.Provider.InfrastructureConfig.Raw = encode(&gcpv1alpha1.InfrastructureConfig{ Networks: gcpv1alpha1.NetworkConfig{ CloudNAT: &gcpv1alpha1.CloudNAT{ //MinPortsPerVM: , NatIPNames: []gcpv1alpha1.NatIPName{ {Name: "test2"}, }, }, }, }) fmt.Println(shoot.Spec.Provider.InfrastructureConfig)}func parseShoot(path string) (*v1beta1.Shoot, error) { var shootSpec *v1beta1.Shoot bytes, err := ioutil.ReadFile(path) if err != nil { return nil, err } err = yaml.Unmarshal(bytes, &shootSpec) if err != nil { return nil, err } return shootSpec, nil}func encode(obj runtime.Object) []byte { data, _ := json.Marshal(obj) return data}

我不太了解園丁的財產(chǎn)。但是您可以做的是為InfrastructureConfig下面的內(nèi)容創(chuàng)建一個結(jié)構(gòu)
type InfraConfig struct {
APIVersion string `json:"apiVersion"`
Kind string `json:"kind"`
Networks struct {
CloudNAT struct {
MinPortsPerVM int `json:"minPortsPerVM"`
NatIPNames []struct {
Name string `json:"name"`
} `json:"natIPNames"`
} `json:"cloudNAT"`
} `json:"networks"`
}
并創(chuàng)建一個引用該對象的變量并將其解組Raw為如下所示。
var existingInfraConfig InfraConfig
err := json.Unmarshal(shoot.Spec.Provider.InfrastructureConfig.Raw, &existingInfraConfig)
然后您可以編輯名稱（您可能想添加一些邏輯來驗證切片以更新正確的索引）并將其編組并將其分配回 InfraConfig，如下所示。
existingInfraConfig.Networks.CloudNAT.NatIPNames[0].Name = "test2"
byteData, _ := json.Marshal(existingInfraConfig)
shoot.Spec.Provider.InfrastructureConfig = &runtime.RawExtension{
Raw: byteData,
Object: nil,
}
總的來說，就像
package main
import (
"encoding/json"
"fmt"
"github.com/gardener/gardener/pkg/apis/core/v1beta1"
"io/ioutil"
"k8s.io/apimachinery/pkg/runtime"
"k8s.io/apimachinery/pkg/util/yaml"
)
type InfraConfig struct {
APIVersion string `json:"apiVersion"`
Kind string `json:"kind"`
Networks struct {
CloudNAT struct {
MinPortsPerVM int `json:"minPortsPerVM"`
NatIPNames []struct {
Name string `json:"name"`
} `json:"natIPNames"`
} `json:"cloudNAT"`
} `json:"networks"`
}
func main() {
shoot, e := parseShoot("test.yaml")
if e != nil {
fmt.Println(e)
}
var existingInfraConfig InfraConfig
err := json.Unmarshal(shoot.Spec.Provider.InfrastructureConfig.Raw, &existingInfraConfig)
fmt.Println(err)
existingInfraConfig.Networks.CloudNAT.NatIPNames[0].Name = "test2"
byteData, _ := json.Marshal(existingInfraConfig)
shoot.Spec.Provider.InfrastructureConfig = &runtime.RawExtension{
Raw: byteData,
Object: nil,
}
fmt.Println(string(shoot.Spec.Provider.InfrastructureConfig.Raw))
}
func parseShoot(path string) (*v1beta1.Shoot, error) {
var shootSpec *v1beta1.Shoot
bytes, err := ioutil.ReadFile(path)
if err != nil {
return nil, err
}
err = yaml.Unmarshal(bytes, &shootSpec)
if err != nil {
return nil, err
}
return shootSpec, nil
}
