json 的 Kubectl 补丁在 Cloud Build 上失败

Question

我可以使用 kubectl 运行从 cli 修补我的入口资源，命令如下：

kubectl patch ingress ingress-resource --type=json -p='[{"op": "replace", "path": "/spec/rules/0/http/paths/0/backend/service/name", "value":"node-app-blue-helm-chart"}]'

当我将以下步骤添加到 cloudbuild.yaml 并执行时，它失败并出现以下错误。

Step #3: Running: kubectl patch ingress ingress-resource --type=json -p='[{"op": "replace", "path": "/spec/rules/0/http/paths/0/backend/service/name", "value":"node-app-blue-helm-chart"}]' 
Step #3: Error from server (BadRequest): json: cannot unmarshal string into Go value of type jsonpatch.Patch
Finished Step #3

我使用的步骤：

  - name: 'gcr.io/cloud-builders/kubectl'
    args:
    - 'patch'
    - 'ingress'
    - 'ingress-resource'
    - '--type=json'
    - '-p=''[{"op": "replace", "path": "/spec/rules/0/http/paths/0/backend/service/name", "value":"node-app-green-helm-chart"}]'' '
    env:
    - 'CLOUDSDK_COMPUTE_ZONE=----'
    - 'CLOUDSDK_CONTAINER_CLUSTER=----'

什么可以缺少？

为了解决这个问题，我尝试像这里提到的那样转义所有“”（）。它没有解决问题。但后来我也划分了“-p”和其余部分，并且还使用了“第二部分。于是工作步骤变成了这样：

  - name: 'gcr.io/cloud-builders/kubectl'
    args:
    - "patch"
    - "ingress"
    - "ingress-resource"
    - "--type=json"
    - "-p"
    - "[{\"op\": \"replace\", \"path\": \"/spec/rules/0/http/paths/0/backend/service/name\", \"value\":\"node-app-green-helm-chart\"}]"
    env:
    - 'CLOUDSDK_COMPUTE_ZONE=----'
    - 'CLOUDSDK_CONTAINER_CLUSTER=----'
