Community helper: Skill for creating and validating CapRover One-Click App templates

[felinto-dev]

Hi CapRover community,

I created a community skill to help people create, convert, and validate CapRover One-Click App templates.

Repository:
https://github.com/felinto-dev/felinto-skills

Skill:
caprover-one-click-app: https://github.com/felinto-dev/felinto-skills/blob/main/.agents/skills/caprover-one-click-app/SKILL.md

Install command: npx skills add https://github.com/felinto-dev/felinto-skills/

The goal is to make it easier for contributors to draft new one-click apps from scratch or convert existing Docker Compose examples into CapRover-compatible YAML.

It includes guidance for:

• captainVersion: 4 template structure
• supported Docker Compose fields in CapRover
• caproverExtra usage
• $$cap_... variables
• service naming conventions
• internal hostnames like srv-captain--$$cap_appname-postgres
• Postgres/Redis/worker patterns
• image tag selection
• post-deploy instructions
• validation checklist
• optional local Docker CLI testing before submitting templates

The Docker testing guidance also tries to be careful with the user's machine:

• temporary containers, networks, volumes, and files should be cleaned up
• images that already existed locally before the test are preserved
• images downloaded only for the test are removed afterwards
• broad cleanup commands like docker system prune are avoided

This is not an official CapRover tool, just a community helper for people using AI coding agents while working on one-click app templates.

Feedback, improvements, and contributions are welcome. If useful, I would be happy to adapt the skill to better match this repository's contribution workflow.
