“k8s.io/apimachinery/pkg/runtime”.Object（缺少方法 DeepCopyObject）

Question

我是 Go 和 Kubernetes 的新手。在制作自定义 K8 schduler 插件时遇到此错误。我使用此链接完成了所有操作Kube-Scheduler-Plugin，一切都已完成，但是当我运行时

./hack/update-codegen.sh

此文件未创建 DeepCopyObject，因为当我运行

make

命令时，它给出了此错误

$ make

make: *** [Makefile:62: build-scheduler] Error 1

我进行了故障排除，但无法找到问题并按应有的方式使用标签。任何人都可以指导进一步排除故障的正确方向。谢谢你

// +k8s:deepcopy-gen:interfaces=k8s.io/apimachinery/pkg/runtime.Object

您想要生成代码的每个包中应该有

doc.go

文件：

.
└── pkg
    └── apis
        └── config
            ├── doc.go
            ├── types.go
            └── v1
                ├── doc.go
                └── types.go

doc.go

文件应包含：

// +k8s:deepcopy-gen=package,register
package {name}

其中

{name}

替换为包名称：

config

和

v1

2 个

types.go

文件中的结构应包含您的注释：

// +k8s:deepcopy-gen:interfaces=k8s.io/apimachinery/pkg/runtime.Object

然后

make

应该可以工作，或者，如果你已经安装了

deepcopy-gen

:

go install k8s.io/code-generator/cmd/deepcopy-gen@latest

您可以：

deepcopy-gen \
--v=9 \
./pkg/apis/config/...

这应该会在两个包中产生

generated.deepcopy.go

文件。

出现错误消息（如下）是因为结构体上没有 DeepCopyObject 方法，无法满足

runtime#Object

接口。

generated.deepcopy.go

文件满足此要求。

cannot use PIDControllerArgs as "k8s.io/apimachinery/pkg/runtime".Object

请参阅

deepcopy-gen

文档。
