Preparation for K8S deployment: namespaces & metafiles

[un-poco]

As a developer, I want to create a development namespace and a production namespace in our Kubernetes cluster. Additionally, I need to create the necessary Kubernetes metadata files for deploying our application. This will allow us to deploy different versions of the service in separate namespaces and provide the required instructions to Kubernetes for deployment.

Acceptance Criteria:

• The development namespace and the production namespace are successfully created in the Kubernetes cluster.
• The namespaces are isolated and can be used to deploy different versions of the service.
• The necessary Kubernetes metadata files (e.g., deployment.yaml, service.yaml, secrets.yaml, postgres.yaml, etc.) are created for deployment.
• The files accurately define the deployment, services, secrets, and any other necessary resources.
