Question

我们拥有Helm 3.0.3和1.18 k8，自一年以来，我们没有遇到过以下任何问题。我们通过头盔将多个微服务部署到k8s，到目前为止一切正常。但是，即使我们未对服务字段进行任何更改，我们也会收到如下错误。

这是我如何部署到k8s的命令。当我在k8s中卸载该服务并开始重建时，它可以正常工作，但是当我需要推送新更改时，ı再次遇到此错误。

+ helm upgrade --install --debug --force xx-ui-dev --values values.dev.yaml --namespace dev --set image.tag=608 .

Answer 1

将public class BackgroundServerFacade implements Runnable { @Override public void run() { ExecutorService newSingleThreadExecutor = Executors.newSingleThreadExecutor(); UpdateCenterImpl updateCenterImpl = new UpdateCenterImpl(newSingleThreadExecutor); updateCenterThread = new Thread(updateCenterImpl); updateCenterThread.start(); } }与--force一起使用时，掌舵使用的是替换策略，而不是补丁。

看看以下helm code：

helm upgrade

替换策略导致您看到的错误。如果您想知道为什么会发生这种情况，请查看this kubectl issue。

Answer 2

@matt是正确的 --force 使用替换策略。

我最近在使用Helm更新服务选择器时遇到了这个问题，因此，为了快速修复/破解，我直接编辑服务并进行所需的更改（更新选择器），然后运行helm命令进行同步（帮助）升级--force release_name ）。

它不会显示服务的任何更改。（纯技巧，但有帮助）

spec.clusterIP：无效值：“”：字段是不可变的
