Thanks, hope I would be able to find why the pod doesnt start at all.
Pods in crashloop will be restarted, but the time between will increase each try. If you delete such pod this will be reset and you should be able to get the logs directly.

You can also look at events.. if your pv config is not correct, or image is missing, pod may never start..

@neo:solsys.orgHaleyTi understand what's running under the surface and how.08:02:44
@jerrykan:matrix.orgjerrykannot sure how up-to-date it is, but https://github.com/kelseyhightower/kubernetes-the-hard-way is worth going though08:03:19
@jerrykan:matrix.orgjerrykanI found it useful to go though, but it is probably also worth having the Kubernetes doco handy to help flesh out the details a bit.08:04:17

Yeah I always delete a pod to get logs. 👍️

@ravi:tchncs.deraviWhy do I get this stream closed error in k9s kubecli for some pods?09:53:29
@ravi:tchncs.deraviSpeculation( forgive me if it sounds too stupid) - I think my helm chart which is too old is now failing as it hasnt been upgraded for some time, a restart of cluster forced some containers to fetch new images from registry some components in the chart were written in the format component:latest and since this is older chart I am unable to start it 🤔 I am trying to run helm upgrade but am wondering if it would fix things.09:56:36

We probably need to know a little more.. like how did you setup the cluster.. and how did you setup the network.. etc..
So I used kubeadm to connect two centos8 workers to an ubuntu18 host. I installed the calico plugin for networking. I did very little else, and now my first container is having dns loopback errors and can't access the external network.

@polyphonic:matrix.orgpolyphonicTrying to solve on my own it seems systemd managing dns servers can conflict with k8s. But configuring it myself (kubelet settings?) Has not gone smoothly.15:23:48

@neo:solsys.orgHaleyQuestion: When installing kubernetes the "kubeadm" method. I don't see where kubernetes is installed with it.08:04:13

Question: When installing kubernetes the "kubeadm" method. I don't see where kubernetes is installed with it.
I think something is installed as a systemd-unit. Other stuff is started in containers from there. Config should be in /etc/kubernetes.

@neo:solsys.orgHaleyok. I'll check. Thx. (Writing the automation script for our envs). Pre-Configuration stuff.12:34:01
