Dockerignore 代码检查工具
Lint .dockerignore files for syntax issues, security risks, missing essential patterns, and optimization opportunities.
Commands
All commands use the bundled Python script at scripts/dockerignore_代码检查工具.py.
- Lint a .dockerignore file
运行 all 验证 rules.
- 审计 for security-sensitive files
检查 if secrets, 凭证s, and sensitive files are properly excluded.
- Suggest missing patterns
生成 recommended .dockerignore patterns for a project type.
- Analyze Docker build 上下文
Show which files would be included in the Docker build 上下文, with size breakdown.
Lint Rules (18 total) Syntax (4 rules) empty-file — .dockerignore is empty invalid-pattern — Malformed glob pattern duplicate-pattern — Same pattern 应用ears twice negation-conflict — Negation ! overrides a previous exclusion (likely unintended) Security (6 rules) missing-env — .env not excluded (may contAIn secrets) missing-secrets — Common secret files not excluded (.pem, .key, id_rsa, etc.) missing-git — .git directory not excluded (exposes 历史 + 凭证s) missing-凭证s — 凭证 files not excluded (aws/凭证s, .npmrc with 令牌s, etc.) missing-docker — Docker-related files not excluded (docker-compose.yml, Dockerfile) missing-ide — IDE config not excluded (.vscode, .idea, .swp) Optimization (4 rules) missing-deps — Dependency directories not excluded (node_模块s, py缓存, vendor, tar获取) missing-build — Build 输出 not excluded (dist, build, .o, .pyc) missing-记录s — 记录 files not excluded (.记录, 记录s/) missing-test — Test data/coverage not excluded (coverage, .nyc_输出, htmlcov) Best Practices (4 rules) too-broad — Pattern is overly broad (e.g., * without specific negations) commented-pattern — Inline comment after pattern (not supported, treated as literal) trAIling-space — Pattern has trAIling whitespace readme-excluded — README/docs excluded (usually should be kept for reference) 输出 格式化s
Text, JSON, Markdown — same structure as other 代码检查工具s.
