Question 1

How do I set up a webhook-triggered recipe in Leprechaun?

Accepted Answer

Define a recipe with `definition: hook` and an `id` in YAML, then start the Leprechaun service. Trigger it by sending an HTTP request to `{host}:{port}/hook?id={recipe_id}`, as specified in the README, enabling integration with external systems like CI/CD pipelines.

Question 2

Can Leprechaun handle job dependencies or retries between recipes?

Accepted Answer

No, Leprechaun focuses on linear step execution within single recipes and doesn't natively support job retries, cross-recipe dependencies, or complex workflow orchestration, unlike tools like Apache Airflow or Jenkins.

Question 3

What's the difference between Leprechaun and using cron with shell scripts?

Accepted Answer

Leprechaun adds abstraction with YAML recipes, step piping, and remote execution, simplifying complex workflows. However, cron is more lightweight and universally available, while Leprechaun offers structured error handling and webhook triggers but requires more setup.

Question 4

How to pipe output from one step to another in a recipe?

Accepted Answer

Use the `}>` syntax at the end of a step command to pipe its output as input to the next step. For example, `echo "text" }>` followed by `cat > file.txt` passes "text" to the second step, as shown in the README's step piping section.

Question 5

Does Leprechaun support email notifications for failed jobs?

Accepted Answer

The README mentions notifications can be configured, but details are sparse—it likely requires external setup. Built-in alerting features are not explicitly documented, unlike some schedulers with integrated monitoring.

Question 6

Is Leprechaun suitable for Windows environments?

Accepted Answer

It's written in Go and uses shell commands, so it might work on Windows with adjustments, but the README doesn't provide specific instructions. Remote execution assumes Unix-like systems, making it best for Linux or macOS.
