Automated Generation of Docker and Kubernetes Configurations Using Large Language Models: A Practical Exploration from a Master's Research

This post shares a master's thesis research whose core is to explore the feasibility and effectiveness of using Large Language Models (LLMs) to automatically generate configuration files for Docker containers and Kubernetes clusters. The research analyzes technical principles, implementation methods, key findings, and application value, providing references for AI-assisted DevOps practices and pointing out that human-machine collaboration is currently the most effective configuration generation mode.

With the popularization of cloud-native technologies, Docker and Kubernetes have become standard for deployment, but writing configurations requires deep professional knowledge, and errors can easily lead to deployment failures, security vulnerabilities, and other issues. Meanwhile, LLMs have shown outstanding performance in code generation, raising the question of 'whether LLMs can be used to automatically generate configurations to lower the threshold', which is exactly the core exploration direction of this master's research.

An empirical research method was adopted, designing experiments covering scenarios from simple to complex (single-container web applications to multi-service microservice architectures, development to production environments). Comparing mainstream LLMs (OpenAI GPT series and open-source models), performance was evaluated from multiple dimensions: grammatical correctness, semantic validity, compliance with best practices, security scores, and manual reviews.

1. LLMs have strong basic generation capabilities; they can generate structurally correct configurations for common scenarios (such as web services and database containerization). 2. The richer the context, the higher the generation quality. 3. Complex scenarios (multi-service coordination, CRDs, etc.) still pose challenges. 4. The human-machine collaboration mode is the most effective, requiring review and adjustment by human experts.

The core architecture includes: 1. Prompt Engineering Layer: Structured prompt templates convert requirements into LLM instructions. 2. Knowledge Enhancement: Injecting official documents, best practices, etc., via RAG to improve professionalism. 3. Validation Feedback Loop: Automated validation (grammar checks, security scans, etc.) and iterative optimization. 4. Version Auditing: Configurations are included in version control, and generation parameters are recorded to ensure traceability.

For development teams: Reduce the learning cost for new members and accelerate environment setup. For operation and maintenance teams: Standardize configurations, reduce human errors, and improve deployment consistency. For education and training: Provide new ideas for cloud-native courses and help learners understand best practices.

Current limitations: Model hallucinations still exist (generating incorrect configurations), and configuration interpretability is insufficient. Future directions: Develop fine-tuned models for the DevOps field, improve validation mechanisms, explore multi-modal inputs, and study configuration evolution scenarios (version upgrade and migration).
