删除包含无效字符的命名空间标签

Question

我的命名空间有一个我想删除的标签“some-param=some-value”。

kubectl label namespace/myNamespace some-param=some-value-

error: invalid label value: "some-param=some-value": a valid label must be an empty string or consist of alphanumeric characters, '-', '_' or '.', and must start and end with an alphanumeric character (e.g. 'MyValue',  or 'my_value',  or '12345', regex used for validation is '(([A-Za-z0-9][-A-Za-z0-9_.]*)?[A-Za-z0-9])?')

无效字符是“=”，但我能够添加此标签。我只是无法删除它。

kubectl version

删除标签的正确命令是：

kubectl label namespace <namespace_name> <label>-

所以在你的用例中它应该是：

kubectl label namespace myNamespace some-param-

您不应该使用完整的 key/value 对和中间的 = 符号，例如 some-param=some-value。

如果您想查看更多 kubectl label 个选项，而不是 these docs。
