- Advanced Docker Networking: Mastering Bridge, Host & Overlay Networks
- Docker provides three main network modes: bridge network, host network and overlay network. 1. The bridge network is suitable for inter-container communication on a single host and is implemented through a virtual bridge. 2. The host network is suitable for scenarios where high-performance networks are required, and the container directly uses the host's network stack. 3. Overlay network is suitable for multi-host DockerSwarm clusters, and cross-host communication is realized through the virtual network layer.

- Dockerfile Best Practices: Writing Efficient and Optimized Images
- How to create an efficient and optimized Docker image? 1. Choose the appropriate basic image, such as official or Alpine image. 2. Arrange the order of instructions reasonably and use the Docker cache mechanism. 3. Use multi-stage construction to reduce the image size. 4. Minimize the number of mirror layers and merge RUN instructions. 5. Clean up temporary files to avoid unnecessary file space.

- Docker Compose Deep Dive: Orchestrating Multi-Container Applications
- DockerCompose defines and manages multi-container applications through YAML files, simplifying the deployment and management of multi-container applications. 1. It allows specifying the configuration of each service, such as mirroring, environment variables, port mapping, etc. 2. DockerCompose reads YAML files, creates and starts containers, and handles service dependencies and network connections. 3. Use docker-composeup to start the application, supporting advanced configurations such as dependencies and health checks. 4. Frequently asked questions include network and volume configuration errors, which can be debugged through log and status checks. 5. Optimization methods include parallel construction of mirrors and horizontal scaling services to improve application performance and maintainability.
