• Install using npm. In your project folder run the following command.

npm install leo-cli -g

leo-cli create

Create a System

A system provides you the opportunity to create a cohesive group of microservices. It is not required, but gives you a moment to consider the overall structure of your project. The leo-cli create commands will create a directory.

leo-cli create system MySystem
cd MySystem

Create a Microservice

A microservice is the central architectural construct

leo-cli create microservice MyService
cd MyService

Create a REST API

Microservice exposed via REST.

leo-cli create resource MyAPI
cd MyAPI

Create a React Application

A front-end application. Also considered a microservice

leo-cli create react MyReactApp
cd MyReactApp

Additional tools for Leo front-end applications:

LEO Authentication - Helps provide cognito authenticated api calls

LEO Authorization - A Front-end Authorization framework that is modeled after AWS Permission structure

Front End Specific Configuration - Configure AWS Cognito for Front End apps

Build Bots

Bots must be created inside a microservice directory

cd /MySystem/MyService
leo-cli create load MyLoadBot
leo-cli create enrich MyEnrichBot
leo-cli create offload MyOffloadBot
leo-cli create bot MyBot
leo-cli create cron MyCronBot

Testing Bots

Inside a bot directory

cd /MySystem/MyService/bots/MyBot
leo-cli test .

Runing Bots

Inside a bot or resource directory

cd /MySystem/MyService/bots/MyBot
leo-cli run .

leo-cli publish - Publishing Microservices & Bots

Publishing a microservice will build all needed lambda functions into zip files and a cloudformation file. Those files are then uploaded to your publish s3 bucket.

The publish command must be run from a micorservice or bot directory

leo-cli publish

Note:

As of version 2.0.0, leo_cli_config.js and leo_config.js are required to be able to publish. See leo-config for config details. Config files are automatically created as part of the Quick Start.

options

• -e --env [environment] Environment.
• --changeset Only build Changeset.
• -c Only build cloudformation.
• -s Save cloudformation.json to the microservice directory.
• -F --force-deploy Force-deploy without requiring confirmation of changeset.
• -d --deploy [environment] Deploy the published cloudformation.
• -f all --force all Force publish and deploy of all bots, including ones without changes.
• --filter idGlobExp Filters the lambdas deployed by the given glob expression. default: *
• --run awsStackName Runs the generated cloudformation.json against the AWS Stack 'awsStackName'. If the stack doesn't exist, it will be crated
• --build Builds the cloudformation and lambdas but doesn't publish them to s3
• --public Makes the s3 publish folder public

Version of the build using the microservice or bot package.json file. If a bot is forced to be built and has the same version number the current timestamp will be appended to he version

Deploy Examples

Publish a Microservice with all new/updated bots

cd /MySystem/MyService
leo-cli publish 

Publish a Microservice and force all bots to build

cd /MySystem/MyService
leo-cli publish --force all

Publish a single bot in a Microservice

cd /MySystem/MyService/bots/MyBot
leo-cli publish

Publish a single bot or resource in a Microservice

cd /MySystem/MyService/bots/MyBot
leo-cli publish 

cd /MySystem/MyService
leo-cli publish --filter MyBot

Deploying a Microservices to AWS

The deploy command can only be run after a microservice has been published. You must be inside a microservice directory to deploy.

The second parameter is the name of the AWS Stack for the microservice.

cd /MySystem/MyService
leo-cli deploy . TestMyService
leo-cli deploy . StageMyService
leo-cli deploy . ProdMyService
