<ul><li>Most production Docker images are bloated. Use multi-stage builds and start from minimal base images to reduce image size.</li><li>By default, Docker containers run as root. Add a non-root user inside your image and avoid mounting the Docker socket unless necessary.</li><li>If your .dockerignore is missing or incomplete, Docker might be copying your entire repo into the image. Use .dockerignore like your .gitignore to avoid unnecessary copying.</li><li>In production, improper volume usage can break statelessness, create permission issues, and introduce state inconsistency between replicas. Only mount named volumes with a clear purpose and make volumes read-only where possible.</li></ul>
