Yo Code - StackState Project Generator

We have written a Yeoman generator to help get you started with StackState extension and customization.

Install the Generator

Install Yeoman and the StackState generator:

npm install -g yo generator-stackstate-lab

Install pre-requisites for generated projects

Install PDM:

Linux

curl -sSL https://raw.githubusercontent.com/pdm-project/pdm/main/install-pdm.py | python3 -

macOS

brew install pdm

Run Yo Code

The Yeoman generator will walk you through the steps required to create your project prompting for the required information.

To launch the generator simply type:

yo stackstate-lab

StackState Agent Check Project Type

The StackState-Lab Generator can scaffold a new StackState Agent Check project using a basic check structure or a more complex structure that uses the StackState ETL Framework.

The generated project uses PDM for Python package and dependency management which supports the latest PEP standards. Especially PEP 582 support, no virtualenv involved at all. PDM Scripts drive the development life-cycle of the project.

Command	Description
pdm install	Installs package and setups up PEP 582 environment
pdm test	Runs unit tests
pdm format	Code styling and linting performed by Black, FlakeHell and MyPy
pdm build	Will transpile the custom agent check to Python 2.7 and create install zip
pdm cleanAgent	Remove the custom StackState Agent Docker image used during development
pdm buildAgent	Build a custom StackState Agent Docker to use during development
pdm check	Dry-run custom agent check inside the StackState Agent container
pdm serve	Starts the StackState Agent in the foreground using the configuration src/data/conf.d/ directory

Command line

Usage:
  yo stackstate-lab:app [<destination>] [options]

  -t,     --projectType         # agent-check...
  -q,     --quick               # Quick mode, skip all optional prompts and use defaults
  -n,     --projectName         # Display name of the project
          --projectDescription  # Description of the project
          --url                 # StackState receiver api url. Example 'https://stackstate.mycompany.com/receiver/stsAgent'
          --apiKey              # StackState Api Key
  -acn,   --agentCheckName      # Name of the agent check
          --gitInit             # Initialize a git repo
          --useEtlFramework     # Use StackState ETL Agent Framework

Arguments:
  destination  # 
    The folder to create the project in, absolute or relative to the current working directory.
    Use '.' for the current folder. If not provided, defaults to a folder with the extension display name.
    Type: String  Required: false

Example usages:
  yo stackstate-lab                               # Create project in a folder with the project's name as prompted in the generator.
  yo stackstate-lab .                             # Create project in current folder
  yo stackstate-lab -acn=Hello -t=agent-check -q  # Create an Agent check project, skip prompts, use defaults.
  yo stackstate-lab -acn=Hello -t=agent-check --useEtlFramework -q  # Create an ETL Agent check project, skip prompts, use defaults.

Run Generator using Docker

If you don't want to install nodejs or any node packages, use this method to containerize the generator.

Go into your project directory.

cd <project directory>

Build the docker image from the docker file.

docker build -t stackstate-lab-generator .

Create a docker container with volumes.

docker run -v $(pwd):/usr/src/app stackstate-lab-generator

Local development

After making necessary changes, run npm link before running yo code to test the local version.

You can learn more about Yeoman generator development on its documentation website.
