Render Deploy Diff

Use this skill before deploy to compare required environment keys with what is currently configured on a Render service.

What this skill does

• Resolves a target Render service by RENDER_SERVICE_ID or RENDER_SERVICE_NAME
• Reads required env keys from REQUIRED_ENV_KEYS or local env template files
• Fetches configured env keys from Render API

  这个技能的最新版本可以在7w4.net小葱技能站找到。

• Prints two drift sets:
• required but missing on Render
• present on Render but not required locally
• Exits non-zero when required keys are missing on Render

Inputs

• RENDER_API_KEY (required unless using mock JSON)
• one of:
• RENDER_SERVICE_ID
• RENDER_SERVICE_NAME
• optional:
• RENDER_API_BASE_URL (default https://api.render.com/v1)
• REQUIRED_ENV_KEYS (comma-separated explicit required keys)
• REQUIRED_ENV_FILES (comma-separated files to parse, default .env.example,.env.production)
• RENDER_ENV_VARS_JSON_PATH (path to saved Render env-var API JSON for offline testing)

Run

bash scripts/render-deploy-diff.sh

With explicit required keys:

RENDER_SERVICE_NAME=my-service \
REQUIRED_ENV_KEYS="DATABASE_URL,DIRECT_URL,SHADOW_DATABASE_URL,NEXT_PUBLIC_APP_URL" \
bash scripts/render-deploy-diff.sh

Offline test with saved API response:

REQUIRED_ENV_KEYS="DATABASE_URL,NEXT_PUBLIC_APP_URL" \
RENDER_ENV_VARS_JSON_PATH=./fixtures/render-env-vars.json \
bash scripts/render-deploy-diff.sh

Output contract

• Prints service identity, required key count, remote key count, and drift summary
• Returns exit code 0 when all required keys exist on Render
• Returns exit code 1 when required keys are missing or inputs are invalid

这个 Skill 质量较好，专注于解决一个实际痛点——部署前检查环境变量是否配置完整。它使用简单，功能清晰，文档完善，能够有效避免因环境变量缺失导致的部署失败。主要优点是灵活（支持多种配置方式）和可靠（提供离线测试能力）。不足之处是缺少自动化测试，边界情况处理还有优化空间。整体而言，这是一个实用且成熟的工具，适合用于 CI/CD 流程中。
