问题 I have configured OIDC with k8s installed using kubeadm. After the configuration, when I run the command kubectl --user=name@gmail.com get nodes I get error: You must be logged in to the server (the server has asked for the client to provide credentials (get nodes)) Can someone please help me with this? 回答1: I use kubectl --username=name@gmail.com get nodes and it works. Earlier I was using the parameter --user instead of --username . 回答2: Your password is probably missing. 来源： https:/

Kubernates pass env variable to “kubectl create”

由 不问归期 提交于 2019-12-07 18:38:27
问题 I need to pass dynamic env variable to kubectl create . Something like this kubectl create -f app.yaml --Target=prod Based on Target code deploys on different servers. 回答1: You can achieve this in two ways: Use Helm. It is a "package manager" for Kubernetes and is built exactly for your use case (dynamic variables to configure behaviour of your resources). If it is only a single variable, "converting" your deployment is as simple as creating a new Helm chart, copy your files into templates/ ,

Is it possible to access the Kubernetes API via https ingress?

由 牧云@^-^@ 提交于 2019-12-06 22:56:27
I was trying unsuccessfully access Kubernetes API via HTTPS ingress and now started to wonder if that is possible at all?

This is bare metal on premise deployment (NO GCE, AWZ, Azure or any other) and there is intension that some environments will be totally offline (which will add additional issues with getting the install packages). Intention is to be able to use kubectl on client host with

由 混江龙づ霸主 提交于 2019-12-06 19:05:12
