kubernetes pod源码解析

https://github.com/kubernetes/api/blob/master/core/v1/types.go

type Pod struct {
	metav1.Typemeta `json:",inline"`
	// Standard object's metadata.
	// More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata
	// +optional
	metav1.Objectmeta `json:"metadata,omitempty" protobuf:"bytes,1,opt,name=metadata"`

	// Specification of the desired behavior of the pod.
	// More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#spec-and-status
	// +optional
	Spec PodSpec `json:"spec,omitempty" protobuf:"bytes,2,opt,name=spec"`

	// Most recently observed status of the pod.
	// This data may not be up to date.
	// Populated by the system.
	// Read-only.
	// More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#spec-and-status
	// +optional
	Status PodStatus `json:"status,omitempty" protobuf:"bytes,3,opt,name=status"`
}

减少一层变量的嵌套

package main
 
import (
	"encoding/json"
	"fmt"
)
 
type Project struct {
	Key   string `json:"key"`
	Value string `json:"value"`
}
 
type JiraHttpReqField struct {
	Project     `json:",inline"`
	Summary     string `json:"summary"`
	Description string `json:"description"`
}
 
func main() {
	dataProject := Project{
		Key:   "key",
		Value: "value",
	}
	dataJiraHttpReqField := &JiraHttpReqField{
		Project:     dataProject,
		Summary:     "Summary",
		Description: "Description",
	}
	data, _ := json.Marshal(dataJiraHttpReqField)
	fmt.Println(string(data))
 
}

转换成json后，对应的key为metadata

如果是空，转换的json对应是{}
