Deploy a Replicated Stateful Application getting fails with Error: ErrImagePull

[Sivakajan-tech]

This is a Bug Report I tried to deploy a Replicated Stateful Application(MySQL) with the guidance of this documentation in the kubernetes. I tried this in the minikube in Ubuntu 22.04.4 LTS. When I apply the service, config and the statefulset yaml file, I got an error of Init:ImagePullBackOff. and only one pod get exposed.(expected 3)

And also when I check the events I got the following response.

19m         Warning   Failed             pod/mysql-0         Error: ErrImagePull

I want to deploy a MySQL stateful set with 3 instances using a common storage as the storage.

The page doesn't specify AMD64 CPU as a requirement. As a minimum change, it should.

@sftim Could you please give me the corrected code?. I don't know where to specify that. THis could be helpful for others also.

Someone (probably not me) would need to write the updated page. Right now, that has yet to happen.

I don't plan to put time into working out any part of the specific page changes that are needed; I am confident I have plenty of other contribution work already planned.
