I have recreated the situation according to the attached tutorial and it works for me. Make sure, that you are trying properly login:

To protect your cluster data, Dashboard deploys with a minimal RBAC configuration by default. Currently, Dashboard only supports logging in with a Bearer Token. To create a token for this demo, you can follow our guide on creating a sample user.

Warning: The sample user created in the tutorial will have administrative privileges and is for educational purposes only.

You can also create admin role:

Getting "rpc error: code = Unavailable desc = error reading from server: EOF" when trying to create a new etcdv3 client

Asked 2022-Mar-21 at 08:25

I'm trying to access my ETCD database from a K8s controller, but getting rpc error/EOF when trying to open ETCD client.

My setup:

ETCD service is deployed in my K8s cluster and included in my Istio service mesh (its DNS record: my-etcd-cluster.my-etcd-namespace.svc.cluster.local)
I have a custom K8s controller developed with use of Kubebuilder framework and deployed in the same cluster, different namespace, but configured to be a part of the same Istio service mesh
I'm trying to connect to ETCD database from the controller, using Go client SDK library for ETCD

If your image has a latest tag, the Pod's ImagePullPolicy will be automatically set to Always. Each time the pod is created, Kubernetes tries to pull the newest image.

Try not tagging the image as latest or manually setting the Pod's ImagePullPolicy to Never. If you're using static manifest to create a Pod, the setting will be like the following:

Disable history in etcd key value store

Asked 2022-Mar-08 at 07:31

Is there any way to disable the history saving in etcd?

I am going to use etcd as KV for my app and I don't need history for the key values.

When I search etcd, I couldn't find about disabling the history.

I don't want to use the compacting feature in etcd.

ANSWER

Answered 2022-Mar-08 at 07:30

Event history is part of etcd.

It was acknowledged, as far back as 2015 in issue 4432 ("Consider moving events out of etcd") that:

Events account for the overwhelming majority of our etcd write volume, which is causing a variety of performance and stability problems.
We could consider a different delivery mechanism for the events.

But for now, this is still managed by etcd.

There are other Key-Value referential which might prove simpler to manage than etcd in your case. I use prologic/bitcask.

ANSWER

Answered 2022-Feb-03 at 08:21

Enable persistence if you want to make it stateful. However I did not see an option to make Grafana a statefulset in the chart you mentioned.

Usually you will see persistence enable option if the corresponding Helm chart support it. For example: you can enable persistence in this grafana helm chart. You may generate template out of it and make use of it in your repo.
