How do I right-size resources for Base images?

Right-sizing resources for base images is crucial for optimizing performance and cost-efficiency in your DevOps pipeline. It involves selecting the appropriate resources for your container images to ensure they are neither over-provisioned nor under-provisioned. This helps in maintaining speed while minimizing resource waste.

Steps for Right-Sizing Base Images

1. Evaluate Usage: Analyze resource usage patterns to determine the requirements.
2. Select Minimal Base Image: Choose a lightweight base image that contains only necessary components.
3. Adjust Resource Limits: Set appropriate CPU and memory limits based on the evaluation.
4. Test and Monitor: Continuously test the application under various loads and monitor resource usage to adjust accordingly.
5. Refine: Based on monitoring data, refine the configuration to better fit operational needs.
