Optimizing Docker for Performance, Security, and Scalability (2 posts)

Docker simplifies application deployment, but optimizing its performance and security is crucial for efficiency. This guide covers best practices such as minimizing image size with multi-stage builds, leveraging layer caching for faster builds, and properly configuring resource limits to prevent bottlenecks. We also explore securing containers with least-privilege access, using optimized networking strategies, and implementing health checks for reliability. Whether you're running containers in development or production, these strategies will help you improve speed, security, and scalability while maintaining efficient resource usage.
