packages |
List of packages to be installed or extracted before running the script. Packages must be specified as a dictionary. Various package sources accepted like apt , snap , url . |
Script params
Your scripts can be parameter-rich. Make it flexible by defining types such as storage
, interface
, and URL
.
For example, in Python:
#!/usr/bin/env python3
# Metadata block here
import argparse
parser = argparse.ArgumentParser(description='')
parser.add_argument('--storage', required=True, help='path to storage device')
args = parser.parse_args()
print(f"Testing: {args.storage}")
Or in Bash:
#!/bin/bash
# Metadata block here
echo "Model: $1"
echo "Serial: $2"
Available Environment Variables
- OUTPUT_STDOUT_PATH: Log path for STDOUT.
- OUTPUT_STDERR_PATH: Log path for STDERR.
- RESULT_PATH: Where to write result YAML.
Real-world Example: Intel C610/X99 HPA Controller
Here’s how to configure an Intel C610/X99 HPA controller on HP systems:
#!/bin/bash -ex
# Metadata here
output=$(sudo hprest get EmbeddedSata --selector HpB...
