Deploy Cloud Functions

Use the tcb fn deploy command to deploy cloud functions to CloudBase environment.

Basic Usage

# Deploy specified cloud function
tcb fn deploy <functionName>

# Deploy all cloud functions in config file
tcb fn deploy

Command Parameters

Parameter	Description	Required
-e, --envId <envId>	Environment ID	No
--code-secret <codeSecret>	Code encryption key, 36 characters of uppercase/lowercase letters and numbers	No
--force	Overwrite function if same name exists	No
--path <path>	Automatically create HTTP access service path	No
--all	Deploy all cloud functions in config file	No
--dir <dir>	Specify cloud function folder path	No

Usage Examples

# Deploy app function
tcb fn deploy app

# Deploy all functions
tcb fn deploy

# Deploy with code encryption
tcb fn deploy app --code-secret 7sGLwMnhgEfKmkqg2dMjB6xWk2hCxsAgGR6w

# Force overwrite function with same name
tcb fn deploy app --force

# Deploy with specified function directory
tcb fn deploy app --dir ./functions/app

Deployment Process

When executing the tcb fn deploy command, CLI automatically completes the following operations:

1. Package and Upload: Package function code as a compressed file and upload
2. Configuration Update: Update function configuration (timeout, memory, environment variables, network configuration, etc.)
3. Trigger Deployment: Deploy or update triggers according to config file

Default Configuration

For Node.js cloud functions, CLI provides default configuration, deployment possible without manual configuration:

{
  "timeout": 5,
  "runtime": "Nodejs10.15",
  "installDependency": true,
  "handler": "index.main",
  "ignore": ["node_modules", "node_modules/**/*", ".git"]
}

Important Notes

• Total function file size cannot exceed 50 MB
• After enabling code encryption, function code and information cannot be viewed in Mini Program IDE or Tencent Cloud Console
• Using --force parameter to overwrite will also overwrite function configuration and triggers
• Environment variable configuration in cloudbaserc.json will completely overwrite online configured environment variables during deployment
