Question

我正在尝试使用Godaddy的K8s客户端修补CRD。

在their example之后，我尝试过：

直接翻译其示例：

                const patchService = await client.apis["serving.knative.dev"].v1alpha1.namespaces('default').services.patch({body: {
                  "spec": {
                    "template": {
                      "spec": {
                        "containers": [
                          {
                            "image": "docker.io/quantomworks/mcsh-site:" + build.metadata.annotations['hook-to-k8s']
                          }
                        ]
                      }
                    }
                  }
                }})

                console.log("Patch result:")
                console.log(patchService)

手动创建服务补丁程序对象，following this example。

const servicePatchObject = [{ op: "replace", path: "/spec/runLatest/configuration/revisionTemplate/spec/container/image", value: "docker.io/quantomworks/mcsh-site:" + build.metadata.annotations['hook-to-k8s']}]

const patchService = await client.apis["serving.knative.dev"].v1alpha1.namespaces('default').services('mcserverhosting-net-site').patch({body: servicePatchObject})

获取一个Yaml文件，我可以使用与成功的kubectl patch services.serving.knative.dev mcserverhosting-net-site --type json -p

匹配的内容来运行

- op: replace
  path: /spec/runLatest/configuration/revisionTemplate/spec/container/image
  value: docker.io/quantomworks/mcsh-site:latest

然后然后直接发布

const patchService = await client.apis["serving.knative.dev"].v1alpha1.namespaces('default').services('mcserverhosting-net-site').patch(servicePatch)

全部导致以下错误：

这不是一个完整的答案，而是另一种选择。切换了put而不是patch。相当于kubectl apply。另外请注意，我并未移动API类型services.service.knative.dev的规范版本属性，但这已经做完了，然后撤消，然后为了代码的合理性而进行了更正。仍然不接受我给的任何东西。一个更清洁的解决方案将是不错的。当前必须以这种方式递增[ResourceVersion][1]，这还不错。

如何正确格式化和发送application / json-patch + json
