如何在kuberetes中使用helm卸载组件

Question

我正在使用helm v3.2.1安装promethus-operator，如下所示：

./helm install stable/prometheus-operator --generate-name -n dabai-pro

现在，我想要将组件prometheus-operator从dabai-pro名称空间移动到monitoring名称空间，并想删除此安装，我阅读了文档并执行了以下操作：

[miao@MeowK8SMaster1 linux-amd64]$ ./helm uninstall stable/prometheus-operator -n dabai-pro
Error: uninstall: Release name is invalid: stable/prometheus-operator

就像这样：

[miaoyou@MeowK8SMaster1 linux-amd64]$ ./helm uninstall prometheus-operator -n dabai-pro
Error: uninstall: Release not loaded: prometheus-operator: release: not found

那么我应该怎么做才能删除它呢？

[miao@MeowK8SMaster1 linux-amd64]$ ./helm list -n dabai-pro
NAME                    NAMESPACE   REVISION    UPDATED                                 STATUS      CHART               APP VERSION

[miao@MeowK8SMaster1 linux-amd64]$ ./helm uninstall prometheus-1591246262
Error: uninstall: Release not loaded: prometheus-1591246262: release: not found
[miao@MeowK8SMaster1 linux-amd64]$ ./helm uninstall prometheus-11.3.0
Error: uninstall: Release not loaded: prometheus-11.3.0: release: not found

Answer 1

使用下面的命令查看版本名称和命名空间名称

helm list 

并通过以下方式卸载发行版：

helm uninstall releasename -n namespacename

在您的情况下，它将是

./helm uninstall prometheus-1591246262 -n dabai-pro
