I am trying to create a Tidb in minikube as per this documentation
Deploy TiDB in the Minikube Cluster | PingCAP Docs.

I got my minikube up and ready on a ec2 t2 large instance
but I have issues with helm, I installed it but I am not able to see the client and server version there
and not able to see any charts
[root@ip-10-148-41-114 bin]# ./helm version

version.BuildInfo{Version:“v3.8.0”, GitCommit:“d14138609b01886f544b2025f5000351c9eb092e”, GitTreeState:“clean”, GoVersion:“go1.17.5”}

[root@ip-10-148-41-114 bin]# ./helm list

Error: Kubernetes cluster unreachable: Get “http://localhost:8080/version”: dial tcp [::1]:8080: connect: connection refused

also I am getting this when I am trying add charts
[ec2-user@ip-10-148-41-114 bin]$ ./helm repo add pingcap https://charts.pingcap.org/

Error: looks like “https://charts.pingcap.org/” is not a valid chart repository or cannot be reached: Get “https://charts.pingcap.org/index.yaml”: EOF

Hi, Seems like this is an outdated doc about minikube, could you refer to the latest one: Get Started With TiDB Operator on Kubernetes | PingCAP Docs

Looks like your kubernetes “cluster” (minikube) isn’t reachable. Are you sure it is running?

ok i will check the new link out, thanks

my minikube is running fine
here is the output
[ec2-user@ip-10-148-41-114 msubramanyam]$ /usr/local/bin/minikube kubectl get pod
NAME READY STATUS RESTARTS AGE

i followed the new link , but still getting error when i use helm while adding ping cap repositories

[ec2-user@ip-10-148-41-114 bin]$ helm repo add pingcap https://charts.pingcap.org/

bash: helm: command not found

[ec2-user@ip-10-148-41-114 bin]$ ./helm repo add pingcap https://charts.pingcap.org/

Error: looks like “https://charts.pingcap.org/” is not a valid chart repository or cannot be reached: Get “https://charts.pingcap.org/index.yaml”: EOF

[ec2-user@ip-10-148-41-114 bin]$

actually i got past that issue and i was able to get minikube, helm etc installed and followed the doc to get the tidb opeerator and components installed but i am not able to see all the services /pods under the tidb name space

[ec2-user@ip-10-148-41-114 bin]$ kubectl get pod -n tidb-cluster

What OS are you using?
Are you using x86_64/am64 hardware or ARM64/Graviton?
What minikube version are you using?
What helm version are you using?

This is how things look for me:

i did all the process as per this doc

but at the end i only see these pods running
[ec2-user@ip-10-148-40-27 bin]$ ./kubectl get po -n tidb-cluster
NAME READY STATUS RESTARTS AGE
basic-discovery-58fc76b4bb-5k2wg 1/1 Running 0 43h

basic-pd-0 1/1 Running 296 (7m11s ago) 43h
basic-tidb-dashboard-0 1/1 Running 0 43h

i dont see expected output as the doc
the basic-tidb and basic-tikv
