How to create a StackStorm Pack

What is a Pack?

Pack is the unit of deployment for integrations and automations in order to extend StackStorm. Typically a pack is organized along service or product boundaries e.g. AWS, Docker, Sensu etc. A pack can contain ActionsWorkflowsRulesSensors.
It is best to view a pack as the means to extend StackStorm and allow it to integrate with an external systems such as Git, Google. AWS, Jenkins, etc.

Create and Contribute a Pack

Packs have a defined structure that is prescribed by StackStorm. It is required to follow this structure while creating your own pack and is also helpful to know while debugging issues with packs.

In the classic Proto-Hack fashion, let's just dive right in and build your first pack!

My first pack

If you would like to create a pack yourself then follow these simple steps. In the example below, we will create a simple pack named hello-st2. The full example is also available atst2/contrib/hello-st2.
  1. First, let’s create the pack folder structure and related files. Let’s keep the metadata files such as pack.yaml, config.yaml, and requirements.txt empty for now.
# Use the name of the pack for the folder name.
mkdir hello-st2
cd hello-st2
mkdir actions
mkdir rules
mkdir sensors
touch pack.yaml
touch config.yaml
touch requirements.txt
