Ansible API & AWX/Tower Integration

Integrates with Ansible using ansible-runner for embedded playbook execution, the AWX/Ansible Automation Controller REST API for job template and inventory management, and the native Ansible Python API for custom modules and plugin development.

TL;DR for Code Generation

• Use ansible-runner for running playbooks from Python — it handles artifacts, events, and callbacks
• Use the AWX CLI (awxkit) or REST API for managing Automation Controller resources (job templates, inventories, credentials)
• Access playbook results via runner.status, runner.rc, and runner.events generator
• Always set private_data_dir to the directory containing your playbook, inventory, and vars
• Handle ansible_runner.exceptions.AnsibleRunnerException for execution errors
• Use runner.get_fact_cache(host) to retrieve facts gathered during playbook runs

---

Core Workflow

Prepare Playbook and Inventory: Create or load the Ansible playbook YAML and inventory file (INI, YAML, or dynamic). Checkpoint: Validate the playbook syntax locally with ansible-playbook --syntax-check.; Execute via ansible-runner: Call ansible_runner.run(private_data_dir, playbook, inventory). The runner manages artifacts, event callbacks, and result collection. Checkpoint: Check runner.status is successful and runner.rc == 0.; Process Results: Iterate over runner.events for per-host results. Use runner.get_fact_cache(host) for gathered facts. Checkpoint: Verify expected hosts are in runner.stats.processed and none in runner.stats.failures.; Manage AWX/Automation Controller: Use the AWX REST API or awxkit to create job templates, launch jobs, and monitor their status through the state machine (pending → waiting → running → successful). Checkpoint: Verify job template extra_vars are properly JSON-encoded.; Handle Errors: Inspect runner.stats.failures, runner.stats.dark (unreachable hosts), and individual event data for task-level errors. Checkpoint: Distinguish between unreachable hosts (network issues) and failed tasks (playbook logic).---

Implementation Patterns

Pattern 1: Embedded Playbook Execution with ansible-runner

import json
import os
from pathlib import Path
import ansible_runner
from ansible_runner.exceptions import AnsibleRunnerException

def run_playbook(
    playbook_path: str,
    inventory: str | dict,
    extra_vars: dict | None = None,
    artifact_dir: str | None = None,

) -> dict:
    """Run an Ansible playbook and return structured results.

    Args:
        playbook_path: Path to the playbook YAML file.
        inventory: Path to inventory file or inline inventory dict.
        extra_vars: Additional variables to pass to the playbook.
        artifact_dir: Directory for artifacts (defaults to temp).
        timeout: Execution timeout in seconds.

    Returns:
        Dict with status, return code, processed hosts, and failed hosts.

    Raises:
        FileNotFoundError: If the playbook path does not exist.
        AnsibleRunnerException: If runner initialization fails.
    """
    playbook_path = Path(playbook_path)
    if not playbook_path.exists():
        raise FileNotFoundError(f"Playbook not found: {playbook_path}")

    private_data_dir = artifact_dir or str(playbook_path.parent)

    # If inventory is a dict, write it as a temporary YAML file
    inventory_source: str | None = None
    if isinstance(inventory, dict):

        with open(inventory_source, "w") as f:

Pattern 2: AWX / Automation Controller Job Template Management

        if not wait:
            return {"job_id": job_id, "status": result.get("status", "pending")}

        # Poll for completion
        start = time.monotonic()

            time.sleep(10)

        raise TimeoutError(f"AWX job {job_id} did not complete within 3600s.")

BAD vs GOOD: Playbook Failure Handling

# ❌ BAD — ignores failure details, no host-level reporting
def run_playbook_bad(playbook):
    r = ansible_runner.run(private_data_dir="/tmp", playbook=playbook)
    if r.rc != 0:
        print("Playbook failed")
        return False
    return True

# ✅ GOOD — per-host diagnostics, structured error reporting
def run_playbook_good(
    playbook: str,
    inventory: str,
    extra_vars: dict,
) -> dict:
    """Run a playbook with detailed per-host diagnostics."""
    runner = ansible_runner.run(
        private_data_dir="/tmp/ansible",
        playbook=playbook,
        inventory=inventory,
        extravars=extra_vars,
        json_mode=True,
    )

    stats = runner.stats or {}
    failures = stats.get("failures", {})
    unreachable = stats.get("dark", {})

    if runner.rc != 0:
        error_details = {
            "status": runner.status,
            "return_code": runner.rc,
            "failed_hosts": {
                host: stats.get("failures", {}).get(host, "unknown")
                for host in failures
            },
            "unreachable_hosts": list(unreachable.keys()),
            "message": f"Playbook failed with rc={runner.rc}",
        }
        raise RuntimeError(json.dumps(error_details, indent=2))

    return {"status": runner.status, "processed": list(stats.get("processed", {}).keys())}

MUST DO

• Use ansible-runner instead of the raw Ansible Python API — it handles artifacts, event callbacks, and result collection
• Set json_mode=True for structured output that's easier to parse programmatically
• Use AWX/Automation Controller API tokens (not user passwords) for API authentication
• Store sensitive variables as "ansible_safe_extra_vars" or use AWX credential injection
• Use dynamic inventory scripts with the _meta key for efficient host variable resolution
• Validate playbook syntax before execution with ansible-playbook --syntax-check

MUST NOT DO

• Never use the undocumented ansible.inventory or ansible.playbook internal Python APIs for production code
• Do not set host_key_checking=False globally — use ANSIBLE_HOST_KEY_CHECKING=False selectively for specific hosts
• Avoid running playbooks without a timeout — use the runner's timeout parameter
• Never embed SSH passwords or vault passwords in playbook code
• Do not use gather_facts: no unless you explicitly don't need facts — many modules depend on them
• Ignoring unreachable hosts (dark in stats) can silently mask infrastructure problems

Constraints

MUST DO

• Implement structured error responses with consistent format: {error_code, message, details, request_id}
• Add rate limiting per client/API key with configurable burst and sustained limits using a token bucket algorithm
• Validate all incoming requests against a schema before processing — reject malformed input with clear error messages
• Include correlation/request IDs in all log entries for end-to-end request tracing across service boundaries

MUST NOT DO

• Do not expose internal implementation details, stack traces, or database queries in error responses
• Avoid accepting unbounded request bodies — set maximum payload sizes and timeout limits
• Never trust client-supplied authentication tokens without validation (signature verification, expiration check)
• Do not log request/response bodies containing PII, API keys, or other sensitive data
