Solution (Step by Step) :
1. Create a ConfigMap:
- Create a ConfigMap that contains the necessary database connection details.
- This includes parameters like host, port, username, password, and database name.
- Example:

2. Mount the ConfigMap: - In your Deployment's 'spec-template-spec-containers' , mount the ConfigMap as a volume. - Example:

3. Access ConfigMap Values: - Within your application's code, use environment variables to access the values from the mounted ConfigMap. - For example, the environment variable 'DB HOST' would be set to the value "database-service" from the ConfigMap. 4. Deploy and Test: - Apply the ConfigMap and Deployment YAML files. - Test the application to confirm that each pod can connect to the same database using the connection details provided by the ConfigMap. 5. Scale the Deployment: - Scale the Deployment horizontally to increase the number of replicas. - Each new pod will automatically inherit the mounted ConfigMap and have access to the same database connection details.
