使用值和命名空间进行 Helm 升级答案

【问题标题】：Helm upgrade with values and namespace使用值和命名空间进行 Helm 升级
【发布时间】：2021-08-10 19:08:00
【问题描述】：

我需要升级 helm chart 中的一些值：

EC2-TEST@~>helm list -A
NAME    NAMESPACE   REVISION    UPDATED                                 STATUS      CHART           APP VERSION
jenkins jenkins     1           2021-06-23 09:21:28.245050889 +0000 UTC deployed    jenkins-3.4.0   2.289.1

EC2-TEST@~>helm repo list
NAME        URL
jenkinsci   https://charts.jenkins.io

图表部署使用：

helm install jenkins -n jenkins -f jenkins-values.yaml

在同一文件夹中新更改的 yaml 图表名称为new-values-jenkins.yaml

尝试了很多变体，看起来是语法问题，收到以下错误：

Error: "helm upgrade" requires 2 arguments

Usage:  helm upgrade [RELEASE] [CHART] [flags]

或：

error: file '/home/ec2-user/jenkins-values.yaml' seems to be a YAML file, but expected a gzipped archive

我尝试过的变体

EC2-TEST@~>helm upgrade -f Jenkins-default-helm.yaml jenkins ./jenkins-values.yaml
Error: file '/home/ec2-user/jenkins-values.yaml' seems to be a YAML file, but expected a gzipped archive

有关正确语法的任何帮助（包括命名空间？）

感谢！（以防万一，带有回滚的选项也很好）

【问题讨论】：

您能否至少包含一些您在升级中尝试过的变体？错误信息应该是不言自明的。
添加了我尝试过的大部分变体。

【解决方案1】：

所以问题是您在命令中缺少实际的图表参考。从这个意义上说，您的安装命令也不正确（可能由于最初的复制粘贴问题或其他原因导致这部分丢失）。

您的安装命令应该是：

helm install jenkins -n jenkins -f jenkins-values.yaml jenkinsci/jenkins

你的升级命令应该是：

helm upgrade jenkins -n jenkins -f jenkins-values.yaml jenkinsci/jenkins

或与您的其他值文件：

helm upgrade jenkins -n jenkins -f Jenkins-default-helm.yaml jenkinsci/jenkins

基本上，请注意您缺少实际的图表参考 - jenkinsci/jenkins 部分。
