Fix: Add GitOps support during stack creation and document API limitations

- Updated portainer_stacks_server.py to support GitOps configuration during stack creation
- Added enable_gitops parameter and related GitOps settings to create_compose_stack_from_git
- Created comprehensive documentation (README_GITOPS.md) explaining:
  - Why GitOps cannot be enabled on existing stacks
  - Why GitOps intervals cannot be updated without recreating stacks
  - API limitations that cause Git-based stacks to detach when updated
- Added test script (test_gitops_create.py) to verify GitOps functionality
- Included portainer_gitops_server.py for reference

The Portainer API requires StackFileContent for updates, which detaches stacks from Git.
This is a fundamental API limitation, not an MCP implementation issue.

# GitOps Implementation Fix for Portainer MCP Servers
## Problem
The Portainer MCP servers were unable to enable GitOps on existing Git-based stacks. The `enable_stack_gitops` function in `portainer_gitops_server.py` was failing with "Invalid stack file content" errors.
## Root Cause
The Portainer API's stack update endpoint (`PUT /api/stacks/{stack_id}`) has limitations:
1. It requires `StackFileContent` to be included in update requests
2. When `StackFileContent` is included, it converts Git-based stacks to file-based stacks
3. This sets `IsDetachedFromGit: true` and clears the `GitConfig`
## Solution
Enable GitOps during stack creation rather than as a separate step. The API supports including `autoUpdate` configuration when creating stacks from Git repositories.
### Implementation Changes
#### Updated `portainer_stacks_server.py`
Added GitOps parameters to the `create_compose_stack_from_git` tool:
```python
# New parameters in the tool schema:
"enable_gitops": {
"type": "boolean",
"description": "Enable GitOps automatic updates",
"default": False
},
"gitops_interval": {
"type": "string",
"description": "GitOps polling interval (e.g., '5m', '1h')",
"default": "5m"
},
"gitops_mechanism": {
"type": "string",
"enum": ["polling", "webhook"],
"description": "GitOps update mechanism",
"default": "polling"
},
"gitops_pull_image": {
"type": "boolean",
"description": "Pull latest images on GitOps update",
"default": True
},
"gitops_force_update": {
"type": "boolean",
"description": "Force redeployment even if no changes",
"default": False
}
```
The implementation now adds `autoUpdate` to the request when creating stacks:
```python
if arguments.get("enable_gitops", False):
auto_update = {
"interval": arguments.get("gitops_interval", "5m"),
"forcePullImage": arguments.get("gitops_pull_image", True),
"forceUpdate": arguments.get("gitops_force_update", False)
}
if arguments.get("gitops_mechanism") == "webhook":
auto_update["webhook"] = arguments.get("gitops_webhook_id", "")
data["autoUpdate"] = auto_update
```
## Usage
### Creating a Stack with GitOps Enabled
```python
# Using the MCP server
await tool.call("create_compose_stack_from_git", {
"environment_id": "6",
"name": "nginx-gitops",
"repository_url": "https://github.com/example/repo",
"repository_ref": "main",
"compose_path": "docker-compose.yml",
"enable_gitops": True,
"gitops_interval": "5m",
"gitops_mechanism": "polling",
"gitops_pull_image": True
})
```
### Direct API Call
```bash
curl -X POST "https://portainer.example.com/api/stacks/create/standalone/repository?endpointId=6" \
-H "X-API-Key: your-api-key" \
-H "Content-Type: application/json" \
-d '{
"name": "nginx-gitops",
"repositoryURL": "https://github.com/example/repo",
"repositoryReferenceName": "main",
"composeFilePathInRepository": "docker-compose.yml",
"repositoryAuthentication": false,
"autoUpdate": {
"interval": "5m",
"forcePullImage": true,
"forceUpdate": false
}
}'
```
## Alternative Approaches
If you need to enable GitOps on existing stacks:
1. **Delete and Recreate**: Delete the existing stack and recreate it with GitOps enabled
2. **Use Webhooks**: Configure webhooks at the Git repository level
3. **External Automation**: Use external tools to trigger stack updates via the Git redeploy endpoint
## Testing
Use the provided `test_gitops_create.py` script to verify GitOps functionality:
```bash
python test_gitops_create.py
```
This will:
1. Create a new stack with GitOps enabled
2. Verify the GitOps configuration
3. Display the stack details including AutoUpdate settings
## Limitations
- Cannot enable GitOps on existing Git-based stacks without detaching them from Git
- Cannot update GitOps settings (like polling interval) on existing stacks without detaching them from Git
- The Portainer API does not provide a way to update Git-based stacks while maintaining Git connection
- Any update that includes `StackFileContent` converts the stack from Git-based to file-based
- This appears to be a fundamental limitation in Portainer's API design
### Why You Cannot Update GitOps Interval
When attempting to update the GitOps interval (e.g., from 5m to 3m) on an existing stack:
1. **API Limitation**: The stack update endpoint (`PUT /api/stacks/{id}`) requires `StackFileContent`
2. **Side Effect**: Including `StackFileContent` in the update request:
- Sets `IsDetachedFromGit: true`
- Clears `GitConfig: null`
- Clears `AutoUpdate: null`
3. **No Partial Updates**: The API doesn't support updating only the `AutoUpdate` configuration
### Workaround
To change the GitOps interval, you must:
1. **Delete the existing stack**
2. **Recreate it with the new interval**
Example:
```bash
# Delete existing stack
curl -X DELETE "https://portainer.example.com/api/stacks/{stack_id}?endpointId={env_id}" \
-H "X-API-Key: your-api-key"
# Recreate with new interval
curl -X POST "https://portainer.example.com/api/stacks/create/standalone/repository?endpointId={env_id}" \
-H "X-API-Key: your-api-key" \
-H "Content-Type: application/json" \
-d '{
"name": "stack-name",
"repositoryURL": "https://github.com/example/repo",
"repositoryReferenceName": "refs/heads/main",
"composeFilePathInRepository": "docker-compose.yml",
"autoUpdate": {
"interval": "3m",
"forcePullImage": true,
"forceUpdate": false
}
}'
```
## Recommendations
1. Always enable GitOps during stack creation if needed
2. Consider opening a feature request with Portainer for enabling GitOps on existing stacks
3. Use the Git redeploy endpoint for manual updates of Git-based stacks
## API Field Reference
The complete `autoUpdate` object structure:
```json
{
"autoUpdate": {
"interval": "5m", // Polling interval (e.g., "1m30s", "5m", "1h")
"forcePullImage": true, // Pull latest images on update
"forceUpdate": false, // Force redeployment even if no changes
"webhook": "webhook-id", // Webhook ID (optional, for webhook mechanism)
"jobID": "15" // Job ID (managed by Portainer)
}
}
```

```
## GitOps Workflow
### 1. **Setup Git Repository**
- Store your Docker Compose or Kubernetes manifests in Git
- Use branches or tags for different environments
- Configure CI/CD pipelines to update manifests
### 2. **Deploy Stack from Git**
- Use the stacks server to create a stack from Git repository
- Provide credentials if using a private repository
### 3. **Enable GitOps**
- Choose between polling or webhook mechanism
- Configure update intervals for polling
- Set force update if you want Git as single source of truth
### 4. **Webhook Integration**
- Add webhook URL to your Git repository
- Configure to trigger on push events
- Use in GitHub Actions or other CI/CD tools
### 5. **Monitor Updates**
- Check GitOps status for stacks
- Review update logs in Portainer
- Use manual triggers for testing
## Update Mechanisms
### Polling
- Portainer periodically checks Git repository for changes
- Default interval: 5 minutes
- Suitable for: Regular updates, less critical deployments
- Pros: Simple setup, no external configuration
- Cons: Delayed updates, resource usage
### Webhooks
- Git repository notifies Portainer of changes
- Immediate updates on push
- Suitable for: CI/CD pipelines, immediate deployments
- Pros: Instant updates, event-driven
- Cons: Requires webhook configuration in Git
## Best Practices
1. **Use Webhooks for Production**: Faster response to changes
2. **Set Appropriate Intervals**: Balance between responsiveness and resource usage
3. **Enable Force Update Carefully**: Can overwrite local changes
4. **Secure Credentials**: Use personal access tokens, not passwords
5. **Test First**: Use manual triggers to test deployments
6. **Monitor Logs**: Check Portainer logs for update status
7. **Version Control**: Use Git tags for production deployments
## Security Considerations
- Git credentials are stored encrypted in Portainer
- Use personal access tokens with minimal permissions
- Webhook URLs contain unique IDs for security
- Enable HTTPS for webhook endpoints
- Regularly rotate Git credentials
- Use read-only tokens when possible
## Troubleshooting
### Common Issues
1. **Updates not triggering**: Check Git credentials and repository access
2. **Webhook failures**: Verify webhook URL and network connectivity
3. **Authentication errors**: Ensure credentials have repository access
4. **Polling delays**: Check interval settings and Portainer logs
### Debug Mode
Enable debug logging by setting in your environment:
```bash
DEBUG=true
LOG_LEVEL=DEBUG
```
## Requirements
- Python 3.8+
- Portainer Business Edition 2.19+ (for full GitOps features)
- Valid Portainer API token
- Git repository with Docker Compose or Kubernetes manifests
- Network access between Portainer and Git repository
