如何将Configmap添加到StatefulSet中的特定Pod? [英] How to add a Configmap to a specific Pod In a StatefulSet?

问题描述

我想知道如何将ConfigMap添加到由StatefulSet生成的特定容器中.

I'd like to know how I can add a ConfigMap to a specific pod spawned by a StatefulSet.

我已经查看了规范，但无法弄清楚如何确保Pod只能挂载带有特定标签的ConfigMap. 我已经以容器的形式准备好了解决方法.但是，我仍然想知道开箱即用的可能性.

I've looked at the spec and I can't figure out how to ensure that a pod only mounts a ConfigMap with a specific label. I've already got a workaround ready in the form of a container. However I'd still like to know if this is possible out of the box.

推荐答案

您不能威胁与相同Pod相同的StatefulSet内的Pod.仅仅是因为您只能指定一个对整个集合都有效的PodSpec.

You can't threat a pod inside the same StatefulSet as a special pod. Simply because you can only specify a single PodSpec that's valid for the whole set.

您可以做的是，但是仍然是一个黑客，将所有版本的配置文件安装在每个Pod中，然后运行一个基于Pod名称使用不同配置文件的入口点脚本.我没有要显示的示例，但是应该很容易

What you could do, but it is still an hack, is mount all versions of the config files in every pod and run an entrypoint script that uses a different config file based on the pod name. I have no example to show but it should be quite easy
