💡 Detailed Explanation: Multi-stage builds allow you to discard heavy build dependencies, resulting in smaller, more efficient production images that save space and improve security.

💡 Detailed Explanation: Multi-stage builds allow you to discard build dependencies and intermediate artifacts, significantly reducing the final image size.

💡 Detailed Explanation: Caching images closer to the compute nodes reduces the need to pull large layers from a remote registry over the network.

💡 Detailed Explanation: Decoupling migrations ensures that schema changes are backward-compatible and finalized before the application code update, preventing locking issues.

💡 Detailed Explanation: Multi-stage builds allow you to compile code in one stage and copy only the final artifact to a minimal runtime image, significantly reducing size.

💡 Detailed Explanation: Rolling back to a stable image restores service quickly while allowing developers to investigate the memory leak in a non-production environment.

💡 Detailed Explanation: Resource Limits in Kubernetes define the maximum amount of memory or CPU a container can consume, preventing any single pod from exhausting node memory.

💡 Detailed Explanation: Multi-stage builds allow you to discard intermediate build artifacts and dependencies, resulting in significantly smaller production images.

💡 Detailed Explanation: OOMKilled means the container exceeded its assigned memory limit. Increasing the memory limit ensures the pod has enough resources.

💡 Detailed Explanation: OOMKilled indicates the container exceeded its memory limit. Describing the pod confirms the exit reason, and monitoring tools help identify if limits were set too low.
