# Deploy Application

Deploy a new application or update an existing one on the Raspberry Pi Kubernetes cluster.

## Usage

```
/deploy <app-name>
/deploy <app-name> --image <image:tag>
/deploy <app-name> --update
```

## What it does

Guides you through deploying an application using the GitOps workflow with ArgoCD.

## Interactive Mode

When run without full arguments, the skill will ask for:

1. **Application name** - Name for the deployment
2. **Container image** - Full image path with tag
3. **Namespace** - Target namespace (default: default)
4. **Ports** - Exposed ports (comma-separated)
5. **Resources** - Memory/CPU limits (defaults provided for Pi)
6. **Pi 3 compatible?** - Whether to add tolerations for Pi 3 node

## Quick Deploy

```
/deploy myapp --image ghcr.io/user/myapp:latest --namespace apps --port 8080
```

## Steps

1. **Check existing state** - See if app exists, current status
2. **Generate manifests** - Create deployment, service, kustomization
3. **Create PR** - Push to GitOps repo, create PR
4. **Sync** - After PR merge, trigger ArgoCD sync
5. **Verify** - Confirm pods are running

## Resource Defaults (Pi-optimized)

```yaml
# Standard workload
requests:
  memory: "64Mi"
  cpu: "50m"
limits:
  memory: "128Mi"
  cpu: "200m"

# Lightweight (Pi 3 compatible)
requests:
  memory: "32Mi"
  cpu: "25m"
limits:
  memory: "64Mi"
  cpu: "100m"
```

## Examples

### Deploy new app
```
/deploy homepage --image nginx:alpine --port 80 --namespace web
```

### Update existing app
```
/deploy api --update --image api:v2.0.0
```

### Deploy to Pi 3
```
/deploy lightweight-app --image app:latest --pi3
```

## Confirmation Points

- **[CONFIRM]** Creating PR in GitOps repo
- **[CONFIRM]** Syncing ArgoCD application
- **[CONFIRM]** Rollback if deployment fails
