Followed: [Generic Kubernetes installation - Percona Operator for MySQL based on Percona XtraDB Cluster](https://www.percona.com/doc/kubernetes-operator-for-pxc/kubernetes.html)

This very first **pxc** pod is stuck on its 3rd container:

> $ kubectl get pods  
> cluster1-pxc-0 **2/3** Running 1 7m40s

> $ **kubectl describe cluster1-pxc-0**  
> Warning Unhealthy 3m6s (x19 over 12m) kubelet Readiness probe failed: mysql: [Warning] World-writable config file ‘/etc/my.cnf’ is ignored.  
> mysql: [Warning] World-writable config file ‘/etc/my.cnf’ is ignored.  
> ERROR 1045 (28000): Access denied for user ‘clustercheck’@‘localhost’ (using password: YES)  
> +[[‘’ == \P\r\i\m\a\r\y]]  
> +exit 1

No changes in yamls were made.

Please suggest what can be the issue!

Hello @IAtheist ,

I have tried to reproduce the issue, but it worked for me - the cluster is up and running with default cr.yaml.

I have a feeling that you missed the step # 5 where Secrets are created. Could you please check?

Is there anything specific about your Kubernetes environment?

Hi Sergey, I have a similar problem with version 1.13.0. Everything works fine except the message I get that the clustercheck password is not set.  
I have applied a secrets (root access works,… in the configured one).

The message I get is the following in the PerconaXtraDBcluster object:

Hello @Manuel_Galan_Privado ,

could you please share the steps to reproduce the problem and manifests that you use? I have hard times reproducing it.
