# Function Compute (FC 3.0) Serverless Devs

## Goals

- Install and validate Serverless Devs.
- Configure credentials, initialize example project, deploy, invoke, and remove.
- Provide CLI flow with Python runtime example.

## Quick Start Flow

1. Install Node.js (14+) and npm.
2. Install and validate Serverless Devs.
3. Configure credentials via guided setup.
4. Initialize example project and enter directory.
5. Deploy, invoke, and optionally remove.

## Install Serverless Devs (npm)

Global install (requires sudo):

```bash
sudo npm install @serverless-devs/s -g
sudo s -v
```

No-sudo alternative (recommended in restricted environments):

```bash
npx -y @serverless-devs/s -v
```

## Configure Credentials (guided)

```bash
sudo s config add
```

Choose `Alibaba Cloud (alibaba)`, provide `AccountID`, `AccessKeyID`, `AccessKeySecret`, and set alias.

## Configure Credentials (command)

Use CLI args to configure credential alias in one command (non-interactive):

```bash
s config add -a default --AccessKeyID <AK> --AccessKeySecret <SK> -f
```

If using environment variables, inject them into the command (example):

```bash
s config add -a default -kl AccessKeyID,AccessKeySecret -il ${ALIBABA_CLOUD_ACCESS_KEY_ID},${ALIBABA_CLOUD_ACCESS_KEY_SECRET} -f
```

Or use Serverless Devs convention JSON environment variable (example):

```bash
export default_serverless_devs_key='{\"AccountID\":\"<AccountID>\",\"AccessKeyID\":\"<AK>\",\"AccessKeySecret\":\"<SK>\"}'
```

Reference in `s.yaml`:

```yaml
access: default_serverless_devs_key
```

## Initialize Example (Python)

```bash
sudo s init start-fc3-python
cd start-fc3-python
```

Initialization creates `s.yaml`, `code/`, and `readme.md`; edit `code/index.py` for function logic.

## Deploy, Invoke, and Remove

```bash
sudo s deploy
sudo s invoke -e "test"
sudo s remove
```
