With the templates in this repository, you can easily run various applications on Sealos without worrying about dependencies between applications. Deploy with one click!
- Browse available templates and find one you like
- Click the "Deploy on Sealos" button in the template documentation
- Configure and deploy - just fill in the required parameters
Template authoring quick links:
- Start from template.yaml (or the Create Template (TODO) button).
- Built-in variables/functions use
GitHub Actions-style syntax; see example.md. - A complete FastGPT example and database Cluster YAML examples (MongoDB/PostgreSQL/MySQL/Redis/Kafka/Milvus/ClickHouse) are in example.md.
That's it! Your app will be running in minutes.
| Template | Description | Deploy |

| ChatGPT-Next-Web | ChatGPT web UI with your own API key | |
| Code-Server | VS Code in your browser | |

- template.yaml - Template reference file
You can create your application template through existing template files or the UI (TODO button).
Copy template.yaml as your starting point:
cp template.yaml my-app-template.yamlTemplate files are divided into two main parts:
- Metadata CR: Template information, default values, and user inputs
- Kubernetes Resources: StatefulSet, Service, Ingress, etc.
For detailed explanation, see example.md.
The system provides built-in environment variables and functions. Use GitHub Actions-like syntax:
# System built-in variable
${{ SEALOS_NAMESPACE }}
# Function to generate random string
${{ random(8) }}
# User input variable
${{ inputs.your_parameter }}See Built-in system variables and functions for complete reference.
The FastGPT example demonstrates how to create a complete template with:
- Default application name and hostname
- User-configurable inputs (API key, password, database type)
- Multiple Kubernetes resources (database, application, ingress)
This repository includes the docker-to-sealos skill (.codex/skills/docker-to-sealos/SKILL.md), which can be called directly from Codex, Claude Code, OpenCode, and OpenClaw to convert Docker Compose apps into Sealos templates.
Use this minimal prompt in your agent:
Use the `docker-to-sealos` skill and convert this GitHub repository to a Sealos template:
https://github.com/<owner>/<repo>
- Replace the URL with your target repository.
- If your agent supports explicit skill calls, invoke it as
$docker-to-sealos. - If your agent uses automatic routing, mentioning
docker-to-sealosin the prompt is usually enough. - The same prompt pattern works across Codex, Claude Code, OpenCode, and OpenClaw.
You can add a "Deploy on Sealos" button to your project's README:
[](https://sealos.io/products/app-store/your-app-name)<a href="https://sealos.io/products/app-store/your-app-name">
<img src="https://sealos.io/Deploy-on-Sealos.svg" alt="Deploy on Sealos"/>
</a>Replace your-app-name with your template's metadata.name from the Template CR.
