根因分析

Helm 升级尝试修改现有 Deployment 上的不可变字段（例如 spec.selector），这是 Kubernetes API 不允许的。

English

A Helm upgrade attempts to modify an immutable field (e.g., spec.selector) on an existing Deployment, which is not allowed by the Kubernetes API.

官方文档

解决方案

  1. 运行 `kubectl delete deployment my-release` 删除 Deployment，然后执行 `helm upgrade --install my-release ./chart` 使用新选择器重新创建。
  2. 如果选择器更改是意外的，回滚：`helm rollback my-release <revision>` 到更改前的版本，然后修改 chart 以避免不可变字段更改。

无效尝试

常见但无效的做法:

  1. 80% 失败

    The --force flag in Helm only recreates resources if the release name changes, but does not bypass immutable field validation on existing resources.

  2. 90% 失败

    Editing the selector after creation is also rejected by the API; the field is immutable for all operations.

  3. 70% 失败

    The old Deployment persists and still has the immutable field; Helm will try to patch it again.
