How can I optimize my Docker containers for better performance?

To optimize your Docker containers, consider using multi-stage builds, minimizing image size, and leveraging caching.

What are multi-stage builds and how do they help?

Multi-stage builds allow you to use multiple FROM statements in your Dockerfile, which helps reduce the final image size by only including necessary artifacts.

Are there any specific tools or commands I should use for caching?

Yes, you can use the Docker build cache effectively by structuring your Dockerfile to minimize changes in layers. Commands like 'docker build --cache-from' can also help.

What about resource limits? How can I set them?

You can set resource limits using the --memory and --cpus flags when running your container, which helps prevent resource contention.
