kubernetes - Helm3 发布历史仅显示最近 10 次修订

Question

可能有一个非常简单的答案，但我遇到了麻烦。

如果提供的 --max 标志值大于 10，Helm 仅显示最后 10 个修订。helm 是否仅存储最后 10 个修订？

$ helm history airflow --max 256 -o table

默认保存的历史记录长度为 10(从 Helm3 开始)。该标志仅在 helm upgrade 中可用(不知道为什么他们没有添加到 install 中):

$ helm upgrade --help  | grep history-max
      --history-max int              limit the maximum number of revisions saved per release. Use 0 for no limit (default 10)
