pipeshell is a simple pipeline execution library allowing you to define and run pipelines of shell commands with dependencies, retries, and other features.
- Define steps with shell commands
- Set dependencies between steps
- Retry steps on failure
- Run steps in the background
- Capture and display step outputs
- Set environment variables for steps
To install pipeshell, you can use pip:
pip install pipeshellHere's a quick example of how to define and run a pipeline with pipeshell:
from pipeshell import pipeline, Step
# Define the steps
prepare_environment = Step(
name="prepare_environment",
command="echo 'Preparing environment...'"
)
fetch_data = Step(
name="fetch_data",
command="curl -o data.txt https://example.com/data.txt",
depends_on=[prepare_environment]
)
process_data = Step(
name="process_data",
command="python process_data.py data.txt processed_data.txt",
depends_on=[fetch_data]
)
analyze_data = Step(
name="analyze_data",
command="python analyze_data.py processed_data.txt results.txt",
depends_on=[process_data]
)
cleanup = Step(
name="cleanup",
command="rm data.txt processed_data.txt",
depends_on=[analyze_data],
allow_failure=True # Allow cleanup to fail without affecting pipeline
)
