The best practice is that people don't interfere with automation because they are prone to errors. When it comes to fixing broken pods in a cluster and scaling apps up and down, that goes beyond the whole point of container automation. As to precisely package up and run anywhere, there is a lot more to look for. If you are looking for a company that provides Kubernetes services, you can search the company like Kubevious.io over the internet.

Operators in Kubernetes are application-specific controllers. Kubernetes Operators are specialized applications and software that encapsulate all operational considerations of an application. It extends the Kubernetes API for building, configuring, and managing complex, non-human applications.
Kubernetes operator is a method of packaging, deploying, and managing K8s applications. It is a dedicated application and extends the Kubernetes API functionality on behalf of Kubernetes users.
How does the Kubernetes Operator work?
An operator is nothing more than a piece of software that does everything a human operator does. Hence, all the tasks of the DevOps members/teams are packaged into the software. Several instructions on how to deploy the application, create replica clusters, recovery instructions, and more. It monitors and always brings the application to the desired state.
Everything in Kubernetes functions like a container.
Operators are no exception. Below are examples of containers with ambassador and operator models. Operators consist of code that executes commands. It also has a Custom Resource Definition which converts operator code back to the kubectl command.
An operator container contains a program that looks at the API and identifies the changes.
Kubectl proxies run in the ambassador container. This helps to connect the carrier container to the K8s API server.
