kubernetes - Openshift/Kubernetes - oc 修补数组的所有元素

Question

我正在尝试将 openshift 服务从使用命令转换LoadBalancer为ClusterIP使用oc patch命令，这需要删除一些元素：

oc -n default patch svc router --type json -p '[\
{ "op" : "remove", "path" : "/spec/externalIPs" },\
{ "op" : "remove", "path" : "/spec/ports/0/nodePort" },\
{ "op" : "replace", "path" : "/spec/type", "value" : "ClusterIP" }]'

这适用于具有单个.spec.ports条目的服务，但是当有多个时，无法将它们全部删除，并且补丁操作失败。

具体来说，它在这部分失败，"op" : "remove", "path" : "/spec/ports/0/nodePort"因为我只指定索引 0。

.spec.ports修补数组的所有元素的正确语法是什么？

这是什么路径语言？它似乎与yamlpath但它只接受有限形式的正斜杠表示法有关。

我尝试了多种变体，它们总是以错误消息结尾，例如Error from server: jsonpatch remove operation does not apply: doc is missing path: /spec/ports/*/nodePort.

一种可能的解决方案是显式删除每个数组索引，直到某个足够高的值，但这很糟糕。

oc -n default patch svc router --type json -p '[\
{ "op" : "remove", "path" : "/spec/externalIPs" },\
{ "op" : "remove", "path" : "/spec/ports/0/nodePort" },\
{ "op" : "remove", "path" : "/spec/ports/1/nodePort" },\
{ "op" : "remove", "path" : "/spec/ports/2/nodePort" },\
{ "op" : "remove", "path" : "/spec/ports/3/nodePort" },\
...
{ "op" : "remove", "path" : "/spec/ports/99/nodePort" },\
{ "op" : "replace", "path" : "/spec/type", "value" : "ClusterIP" }]'

示例服务 YAML：
