如何使用kubeadm升级来更改kubeadm-config中的某些功能 [英] How to use kubeadm upgrade to change some features in kubeadm-config

问题描述

我想在现有的kubernetes集群(v1.10)上安装kube-prometheus.在此之前，医生说我需要将控制器/调度程序的IP地址从127.0.0.1更改为0.0.0.0.并且还建议使用 kubeadm配置升级进行更改这些功能:

I want to install kube-prometheus on my existing kubernetes cluster(v1.10). Before that, the doc says I need to change the ip address of contrller/scheduler from 127.0.0.1 to 0.0.0.0. And it also recommand to use kubeadm config upgrade to change these features:

controllerManagerExtraArgs:
  address: 0.0.0.0
schedulerExtraArgs:
  address: 0.0.0.0

阅读文档后，我尝试使用以下命令，但没有成功:

After reading the doc, i tried with the below command, but it didn't work:

kubeadm upgrade --feature-gates controllerManagerExtraArgs.address=0.0.0.0 

我知道我可以使用kubectl -n kube-system edit cm kubeadm-config直接修改configMap，只想知道如何从kubeadm upgrade

I know i can use kubectl -n kube-system edit cm kubeadm-config to modify configMap directly, just want to know how to upgrade it from kubeadm upgrade

推荐答案

我知道的唯一方法是使用--config选项.

The only way I know of is to use the --config option.

生成一个如下所示的yaml文件:

Generate a yaml file that looks like this:

controllerManagerExtraArgs:
  address: 0.0.0.0
schedulerExtraArgs:
  address: 0.0.0.0

然后运行:

kubeadm upgrade apply --config /etc/kubeadm.yaml
