Types

type AppFile

type AppFile struct {
	Name       string             `json:"name"`
	CreateTime time.Time          `json:"createTime,omitempty"`
	UpdateTime time.Time          `json:"updateTime,omitempty"`
	Services   map[string]Service `json:"services"`
	Secrets    map[string]string  `json:"secrets,omitempty"`
	// contains filtered or unexported fields
}

AppFile defines the spec of KubeVela Appfile
