oc 補丁替換圖像名稱錯誤“json：無法將 object 解組為 Go 類型的 jsonpatch.Patch 值”

Question

我需要對以下部署應用 oc 補丁，更改“圖像”的 de 值。 但是我不能這樣做，這是由一個錯誤引起的：

部署 YML：

                            }

                            }
  ],
                        "resources": {
                        ...

我正在嘗試以下內容：

root@oc-jump-pod:/# oc patch deploy push-engine --type='json' -p='{"spec":{"template":{"metadata":{"spec":{"containers":{"image":"registry.sdi.
dev.weu.azure.paas.cloudcenter.corp/test-dev/test:0.0.1"}}}}}}'
Error from server (BadRequest): json: cannot unmarshal object into Go value of type jsonpatch.Patch

這是為了獲得價值

root@oc-jump-pod:/# oc get deploy push-engine -o=jsonpath='{..image}'
registry.sdi.dev.weu.azure.paas.cloudcenter.corp/test-dev/test-java:0.0.2

我需要這樣做，將圖像的標簽從 0.0.2 更改為 0.0.1（或其他）。 可能我還不了解 oc 補丁，實際上我在 oc 控制台上手動進行更改。 但是這種方法，很粗魯，不遵循 CI/CD。

Answer 1

Deployment的正確 JSON 補丁文檔可能如下所示：

[
    {
        "op": "replace",
        "path": "/spec/template/spec/containers/0/image",
        "value": "registry.sdi.dev.weu.azure.paas.cloudcenter.corp/test-dev/test:0.0.1"
    }
]

您的示例不會起作用，因為它不反映原始yaml文件的結構。 請注意，它包含arrays [...]並且您將其視為僅包含地圖{...} 。

您最終的oc patch命令可能如下所示：

oc patch deploy push-engine --type='json' -p '[{ "op": "replace", "path": "/spec/template/spec/containers/0/image", "value": "registry.sdi.dev.weu.azure.paas.cloudcenter.corp/test-dev/test:0.0.1" }]'
