How to use the Leo CLI

Create a System

A system is the root directory for a group of microservices & bots. This command will create a directory for the system.

leo-cli create system MySystem

Create a Microservice

Microservices must be created inside a system directory

cd /MySystem
leo-cli create microservice MyService

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 .

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 .


  • --region awsRegion Sets the AWS Region. default: us-west-2
  • --filter idGlobExp Filters the lambdas deployed by the given glob expression. default: *
  • --force botId|all Forces a bot to build even if the versions are the same (Must be included in --filter expression). default: false
  • --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
