## Description
The Declarative Deployment pattern involves defining the desired state of your application and letting Kubernetes handle the deployment process. This includes rolling updates and fixed updates to transition between application versions. Kubernetes ensures that the desired state is maintained by automatically creating, updating, and deleting resources as needed.


## Use Cases
Use when you want Kubernetes to manage deployment updates or when you need reliable application rollouts with rollback capabilities.





## Trade-offs


### Advantages

- Automated deployment management

- Self-healing capabilities

- Easy rollback to previous versions

- Consistent deployment across environments




### Considerations & Drawbacks

- Requires understanding of Kubernetes deployment strategies

- May need health checks for smooth rollouts

- Can be slower than imperative deployments
