如何替换或找到正确的路径

Question

我有部署，我想替换“路径”值在活性探测部分。什么是正确的道路，这在库斯托梅斯？

- patch: |-
    - op: replace
      path: ??????????
      value:
        https://xyz.staging.something.eu/ping

    apiVersion: v1
    kind: Pod
    metadata:
      labels:
        test: liveness
      name: liveness-http
    spec:
      containers:
      - name: liveness
        image: k8s.gcr.io/liveness
        args:
        - /server
        livenessProbe:
          httpGet:
            path: /healthz
            port: 8080
          initialDelaySeconds: 3
          periodSeconds: 3

我正在尝试语法containers[name=xx]及其在containers/0工作时的失败。我不知道我是否遗漏了什么或者这是不被支持的，找不到更多关于这个语法的例子。

详情如下：

使用kustomize版本进行检查：

• v4.5.4
• v4.5.2

test.yaml：

---
apiVersion: v1
kind: Pod
metadata:
  name: test-pod
spec:
  containers:
    - name: test-container
      env:
      - name: environment
        value: stage
      - name: api_port
        value: "8080"
      image: docker.io/bitname/posgresql:latest
      ...
      ...

kustomization.yaml

apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization

...
...

patchesJson6902:
- target:
    version: v1
    kind: Pod
    name: test-pod
  path: replace.yaml

replace.yaml

- op: replace
  path: "/spec/containers[name=test-container]/env/0/value"
  value: "dev"
# doesn't work: `Error: replace operation does not apply: doc is missing path" /spec/containers[name=test-container]/env/0/value: missing value
 

- op: replace
  path: "/spec/containers/0/env/0/value"
  value: "dev"
# works as expected

谢谢!
