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: 0.0.0.0After reading the doc, i tried with the below command, but it didn't work:
kubeadm upgrade --feature-gates controllerManagerExtraArgs.address=0.0.0.0 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
The only way I know of is to use the --config option.
Generate a yaml file that looks like this:
controllerManagerExtraArgs:
address: 0.0.0.0
schedulerExtraArgs:
address: 0.0.0.0and then run:
kubeadm upgrade apply --config /etc/kubeadm.yaml
