#Kubeless - Quick Start

#Pre-requisites

  1. Node.js v6.5.0 or later.
  2. Serverless CLI v1.20 or later. You can run npm install -g serverless to install it.
  3. Install Kubeless & Dependencies(../installation).

#Create a new service

Create a new service using the Python template, specifying a unique name and an optional path for your service.

# Create a new Serverless Service/Project
$ serverless create --template kubeless-python --path new-project
# Change into the newly created directory
$ cd new-project
# Install npm dependencies
$ npm install

#Deploy, test and diagnose your service

  1. Deploy the Service

Use this when you have made changes to your Functions, Events or Resources in serverless.yml or you simply want to deploy all changes within your Service at the same time.

serverless deploy -v
  1. Deploy the Function

Use this to quickly upload and overwrite your function code, allowing you to develop faster.

serverless deploy function -f hello
  1. Invoke the Function

Invokes the Function and returns results.

$ serverless invoke --function hello --data '{"Kubeless": "Welcome!"}' -l
# results
{ body: '{"input": {"Kubeless": "Welcome!"}, "message": "Go Serverless v1.0! Your function executed successfully!"}',
statusCode: 200 }
  1. Fetch the Function Logs

Open up a separate tab in your console and stream all logs for a specific Function using this command.

serverless logs -f hello -t

#Cleanup

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.

serverless remove
