## What is reflex cloud config?

The following command:

```bash
reflex cloud config
```

generates a `cloud.yml` configuration file used to deploy your Reflex app to the Reflex cloud platform. This file tells Reflex how and where to run your app in the cloud.

## Configuration File Structure

The `cloud.yml` file uses YAML format and supports the following structure. **All fields are optional** and will use sensible defaults if not specified:

```yaml
# Basic deployment settings
name: my-app-prod                    # Optional: defaults to project folder name
description: 'Production deployment' # Optional: empty by default
projectname: my-client-project          # Optional: defaults to personal project

# Infrastructure settings
regions:                            # Optional: defaults to sjc: 1
  sjc: 1                           # San Jose (# of machines)
  lhr: 2                           # London (# of machines)
vmtype: c2m2                       # Optional: defaults to c1m1

# Custom domain and environment
hostname: myapp                    # Optional: myapp.reflex.dev
envfile: .env.production           # Optional: defaults to .env

# Additional dependencies
packages:                          # Optional: empty by default
  - procps
```

## Configuration Options

For details of specific sections click the links in the table.

### Projects

Organize deployments using projects:

```yaml
projectname: client-alpha    # Groups related deployments
```

You can also specify a project uuid instead of name:
```yaml
project: 12345678-1234-1234-1234-1234567890ab
```

You can go to the homepage of the project in the reflex cloud dashboard to find your project uuid in the url `https://build.reflex.dev/project/uuid`

### Apt Packages

Install additional system packages your application requires. Package names are based on the apt package manager:

```yaml
packages:
  - procps=2.0.32-1  # Version pinning is optional
  - imagemagick 
  - ffmpeg      
```

### Include SQLite

Include local sqlite database:

```yaml
include_db: true
```

This is not persistent and will be lost on restart. It is recommended to use a database service instead.

### Strategy

Deployment strategy:
Available strategies:
- `immediate`: [Default] Deploy immediately
- `rolling`: Deploy in a rolling manner
- `bluegreen`: Deploy in a blue-green manner
- `canary`: Deploy in a canary manner, boot as single machine verify its health and then restart the rest.

```yaml
strategy: immediate
```

## Multi-Environment Setup

**Development (`cloud-dev.yml`):**
```yaml
name: myapp-dev
description: 'Development environment'
vmtype: c1m1
envfile: .env.development
```

**Staging (`cloud-staging.yml`):**
```yaml
name: myapp-staging
description: 'Staging environment'
regions:
  sjc: 1
vmtype: c2m2
envfile: .env.staging
```

**Production (`cloud-prod.yml`):**
```yaml
name: myapp-production
description: 'Production environment'
regions:
  sjc: 2
  lhr: 1
vmtype: c4m4
hostname: myapp
envfile: .env.production
```

Deploy with specific configuration files:

```bash
# Use default cloud.yml
reflex deploy

# Use specific configuration file
reflex deploy --config cloud-prod.yml
reflex deploy --config cloud-staging.yml
```
