LF Tools UV

This project's documentation is available on ReadTheDocs (RTD) and GitHub Pages:

• Official Documentation: https://lftools-uv.readthedocs.io
• GitHub Pages: https://lfreleng-actions.github.io/lftools-uv/

LF Tools UV is a collection of scripts and utilities that are useful to Linux Foundation projects' CI and Releng related activities. We try to create these tools to be as generic as possible such that they are reusable in other CI environments.

CLI Interface

lftools-uv uses Typer as the CLI library. For CI/CD environments that require the previous Click-based output format, use LEGACY_CLI=1.

Installation

Using uv (Recommended)

This project uses uv for fast Python package management.

1. Install uv:

   curl -LsSf https://astral.sh/uv/install.sh | sh

2. Install lftools-uv:

   uv pip install lftools-uv

3. Or install with all extras for development:

   uv pip install "lftools-uv[all]"

Using pip

pip install lftools-uv

Configuration

lftools uses configuration files in the standard ~/.config/lftools/ directory for Jenkins, OpenStack, and other service credentials.

Quick Setup

Use the setup helper to create example configuration files:

# Clone the repository first (if not already done)
git clone https://github.com/lfreleng-actions/lftools-uv.git
cd lftools-uv

# Run the configuration setup helper
./scripts/setup-config.sh

This creates:

• ~/.config/lftools/jenkins_job.ini - Jenkins server configurations
• ~/.config/lftools/clouds.yaml - OpenStack cloud configurations

Manual Configuration

Create the configuration directory:

mkdir -p ~/.config/lftools

Copy and customize the example files:

# Jenkins configuration
cp etc/lftools/jenkins_job.ini.example ~/.config/lftools/jenkins_job.ini
# Edit with your Jenkins credentials

# OpenStack configuration
cp etc/lftools/clouds.yaml.example ~/.config/lftools/clouds.yaml
# Edit with your OpenStack credentials

Testing Configuration

Test your configuration with basic commands:

# Test Jenkins connectivity
lftools jenkins -s onap-prod plugins list

# Test OpenStack connectivity
lftools openstack --os-cloud production image list

# Run comprehensive functional tests (see Functional Testing section below)
./scripts/run_functional_tests.sh

For detailed configuration instructions, see: docs/configuration.md

Functional Testing

The repository includes a comprehensive functional test harness that validates lftools-uv commands against real infrastructure (Jenkins, OpenStack, Nexus, GitHub, etc.).

Basic Usage

# Run all Category 1 (safe/read-access) tests
./scripts/run_functional_tests.sh

# Run with debug output (shows command output to terminal)
./scripts/run_functional_tests.sh debug

# Filter tests by substring
TEST_FILTER=jenkins ./scripts/run_functional_tests.sh

# Run specific category with debug output
TEST_CATEGORY=1 DEBUG=1 ./scripts/run_functional_tests.sh

Configuration Requirements

The functional tests work with standard lftools configuration files:

Jenkins Tests

• File: ~/.config/lftools/jenkins_job.ini
• Environment: JENKINS_URL, LFTOOLS_USERNAME, LFTOOLS_PASSWORD
• Default: Uses jenkins.onap.org (read-access operations)

OpenStack Tests

• File: ~/.config/lftools/clouds.yaml
• Environment: OS_CLOUD (default: ecompci)
• Required: Valid OpenStack credentials for cloud operations

Nexus Tests

• Environment: NEXUS2_FQDN (default: nexus.onap.org), NEXUS3_FQDN (default: nexus3.onap.org)
• Operations: Read-access repository queries

GitHub Tests

• Environment: GITHUB_ORG (default: onap), GITHUB_TOKEN
• File: Can use lftools config for token storage

Test Categories

• Category 1: Safe, read-access operations (default)
• Category 2: Reversible operations (disabled by default)
• Category 3: Destructive operations (disabled by default)

Advanced Options

# Environment variables
TEST_CATEGORY=1,2          # Run two categories
TEST_FILTER=openstack      # Filter by substring
STOP_ON_FAILURE=1          # Stop after first failure
DRY_RUN=1                  # Show what would run
DEBUG=1                    # Show command output
VERBOSE=1                  # More logging
OUTPUT_FORMAT=json         # JSON output format

# Examples
TEST_FILTER=nexus DEBUG=1 ./scripts/run_functional_tests.sh
STOP_ON_FAILURE=1 ./scripts/run_functional_tests.sh debug

Debug Mode

Debug mode displays actual command output to the terminal while tests run:

# Enable debug mode
./scripts/run_functional_tests.sh debug
DEBUG=1 ./scripts/run_functional_tests.sh

# Debug specific tests
TEST_FILTER=openstack ./scripts/run_functional_tests.sh debug
```text

**Debug Output Example:**

```text
2025-09-20T09:12:32Z [INFO] DEBUG mode active (displaying command output)
2025-09-20T09:12:32Z [INFO] Running (1) core.version - Show lftools-uv version
2025-09-20T09:12:32Z [INFO] === Command Output for core.version ===
lftools-uv 0.1.5.dev2
2025-09-20T09:12:32Z [INFO] === End Output for core.version ===
2025-09-20T09:12:32Z [OK] PASS core.version (0 ms)

Log Files

Test output is always logged to files regardless of debug mode:

• Location: .functional_logs/ directory
• Format: {test_id}.log files
• Content: Complete command output for analysis

Quick Setup for Testing

# 1. Set up configuration files
./scripts/setup-config.sh

# 2. Run some basic tests
TEST_FILTER=core ./scripts/run_functional_tests.sh debug

# 3. Test specific functionality
TEST_FILTER=jenkins ./scripts/run_functional_tests.sh debug
TEST_FILTER=openstack ./scripts/run_functional_tests.sh debug

# 4. Run all safe tests
./scripts/run_functional_tests.sh

Most tests pass with default ONAP/ECOMPCI configurations, making it easy to verify your lftools-uv installation and basic connectivity.

Using uvx for CI/CD (Recommended)

uvx is ideal for CI/CD environments and one-off executions where you want to run lftools-uv without affecting the existing Python environment. It creates an isolated virtual environment for each execution, preventing dependency conflicts with other tools in your pipeline.

uvx Basic Usage

Run lftools-uv commands directly without installation:

# Basic command execution
uvx lftools-uv version

# Run with help
uvx lftools-uv --help

Using Optional Dependencies

When using features that require optional dependencies (like LDAP or OpenStack), you need to specify the extras:

# For LDAP functionality - note the quotes to prevent shell expansion
uvx "lftools-uv[ldap]" ldap --help

# For OpenStack functionality
uvx "lftools-uv[openstack]" openstack --help

# Combined extras
uvx "lftools-uv[ldap,openstack]" --help

# All extras for full functionality
uvx "lftools-uv[all]" --help

Alternative uvx Syntax

You can also use the --from flag for clarity:

# Same as the above
uvx --from "lftools-uv[ldap]" lftools-uv ldap csv mygroup
uvx --from "lftools-uv[openstack]" lftools-uv openstack --help

CI/CD Pipeline Examples

GitHub Actions:

- name: Deploy artifacts with lftools-uv
  run: |
    uvx lftools-uv deploy nexus-zip \
      --nexus-url ${{ secrets.NEXUS_URL }} \
      --nexus-repo releases \
      ./artifacts/*.zip

GitLab CI:

deploy:
  script:
    - uvx "lftools-uv[all]" deploy logs --help
    - uvx lftools-uv sign sigul ./artifacts/

Jenkins Pipeline:

pipeline {
    agent any
    stages {
        stage('Deploy') {
            steps {
                sh 'uvx lftools-uv version'
                sh 'uvx "lftools-uv[ldap]" ldap csv project-committers'
            }
        }
    }
}

Benefits of uvx in CI/CD

• Isolation: No interference with existing Python packages in the CI environment
• Speed: Automatic caching of environments between runs
• Consistency: Same tool version across different pipeline stages
• No Setup: No need to manage virtual environments or installations
• Clean: Environments are automatically cleaned up after execution
