Complete the steps in this guide to install the Serverless Framework open-source CLI and deploy a sample Service on Tencent Cloud that reports deployment information and operational metrics to the Serverless Framework.
There are a few prerequisites you need to install and configure:
- Install Node.js 6.x or later on your local machine
- Install the Serverless Framework open-source CLI version 1.47.0 or later
If you already have these prerequisites setup you can skip ahead to deploy an example Service.
- Follow these installation instructions.
- At the end, you should be able to run
node -vfrom your command line and get a result like this...
$ node -v vx.x.x
- You should also be able to run
npm -vfrom your command line and should see...
$ npm -v x.x.x
- Run this command in your terminal
npm install -g serverless
- After install is complete, you should be able to run
serverless -vfrom your command line and get a result like this...
$ serverless -v x.x.x
Now that you’ve completed your setup, let’s create and deploy a serverless Service.
- Use the Serverless Framework open-source CLI to create a new Service with
# Create a new Serverless service/project $ serverless create --template tencent-nodejs --path my-service 2. Install the dependencies ```sh # Change into the newly created directory $ cd my-service $ npm install
Configure your Tencent Cloud account to work with the Serverless Framework.
An Event is anything that can trigger your serverless functions. In this case, you need to define a endpoint in your
serverless.yml that will trigger your serverless function.
service: my-service # service name provider: # provider information name: tencent runtime: Nodejs8.9 credentials: ~/credentials plugins: - serverless-tencent-scf functions: hello_world: handler: index.main_handler runtime: Nodejs8.9 events: - apigw: name: hello_world_apigw parameters: stageName: release serviceId: integratedResponse: true httpMethod: ANY
Use this command to deploy your service for the first time and after you make changes to your Functions, Events or Resources in
serverless.yml and want to deploy all changes within your Service at the same time.
More information in deploy command
Replace the URL in the following curl command with your returned endpoint URL, which you can find in the
sls deploy output, to hit your URL endpoint.
$ curl -X POST https://service-xxxx-1300000000.ap-guangzhou.apigateway.myqcloud.com/release/
Invokes a Function and returns logs.
serverless invoke -f hello_world
More information in invoke command
Open up a separate tab in your console and stream all logs for a specific Function using this command.
serverless logs -f hello_world -t
If at any point you no longer need your Service, you can run the following command to remove the Functions, Events and Resources that were created. This will delete the resources you created and ensure that you don't incur any unexpected charges.
