# ArgoCD CLI Login

ArgoCD CLI authentication with SSO for the Data Portal cluster.

## When to Use

Use this skill automatically when:
- User requests ArgoCD login or authentication
- User mentions accessing ArgoCD cluster or applications
- User needs to interact with ArgoCD CLI tools
- Authentication errors occur when using ArgoCD commands

## Authentication Command

```bash
argocd login argocd.dataportal.fi --grpc-web --sso
```

### Command Breakdown

- `argocd.dataportal.fi` - Data Portal ArgoCD server endpoint
- `--grpc-web` - Enable gRPC-Web protocol (required for web-based SSO)
- `--sso` - Use Single Sign-On authentication (opens browser for OAuth2 flow)

## Usage Flow

1. **Detect authentication need:**
   - User explicitly requests login
   - ArgoCD command fails with authentication error
   - User mentions accessing ArgoCD cluster

2. **Execute login command:**
   ```bash
   argocd login argocd.dataportal.fi --grpc-web --sso
   ```

3. **Guide user through SSO:**
   - Command will open browser automatically
   - User completes SSO authentication in browser
   - CLI receives token upon successful authentication
   - Session is stored in `~/.config/argocd/config`

4. **Verify authentication:**
   ```bash
   argocd account get-user-info
   ```

## Common ArgoCD Operations (Post-Login)

### Application Management
```bash
# List applications
argocd app list

# Get application details
argocd app get <app-name>

# Sync application
argocd app sync <app-name>

# View application resources
argocd app resources <app-name>
```

### Cluster Information
```bash
# List clusters
argocd cluster list

# Get cluster info
argocd cluster get <cluster-name>
```

### Project Management
```bash
# List projects
argocd proj list

# Get project details
argocd proj get <project-name>
```

## Authentication Session

- **Session storage:** `~/.config/argocd/config`
- **Session persistence:** Tokens have configurable expiration
- **Re-authentication:** Run login command again when sessi
