\u2714 NO - Safe
Must be in C:\\Program Files\\Red Hat\\Ansible Runner\\ansible-runner.exe
Can I Disable?
\u2714 YES - Will stop automation until re-enabled
Disabling may stop automation jobs and CI workflows that rely on Ansible Runner
Is it Safe to Remove?
\u2714 YES - You can uninstall if not required
Close automation jobs to free resources and avoid background runs
What is ansible-runner.exe?
ansible-runner.exe is the executable component of the Ansible Runner framework. It orchestrates the execution of Ansible playbooks by loading inventory, credentials, and environment settings, then captures output, events, and artifacts. It is commonly used in CI pipelines and automation platforms to run Ansible tasks reliably.
Ansible Runner launches ansible-playbook under a controlled process, exposing an event stream and an artifacts directory, while integrating with inventory, vaults, and callbacks. It helps you isolate and audit automation runs.
Quick Fact: Ansible Runner provides a reproducible runtime for Ansible tasks, enabling consistent job execution across development, CI, and production environments.
Types of Ansible Runner Processes
- Runner Process: Executes Ansible playbooks and handles the job lifecycle
- Event Dispatcher: Collects task events and logs to artifacts
- Credential Helper: Manages vaults and credentials for playbooks
- Inventory Loader: Parses inventory and host variables for runs
- Callback Plugin: Sends results to external systems or dashboards
Is ansible-runner.exe Safe?
Yes, ansible-runner.exe is safe when downloaded from official sources (the Ansible project or Red Hat channels) and executed in a trusted Windows environment.
Is ansible-runner.exe a Virus or Malware?
The genuine ansible-runner.exe is not a virus. However, always verify the file location and digital signature, as attackers may disguise malware with similar names.
How to Tell if ansible-runner.exe is Legitimate or Malware
- File Location:: Must be in
C:\\Program Files\\Red Hat\\Ansible Runner\\ansible-runner.exe or C:\\Program Files (x86)\\Red Hat\\Ansible Runner\\ansible-runner.exe. Any other location is suspicious.
- Digital Signature:: Right-click ansible-runner.exe -> Properties -> Digital Signatures. Should show "Red Hat, Inc." or the official Ansible project signer.
- Resource Usage:: Normal usage is 2-15% CPU and 80-200 MB memory per active run. Constant high resource usage when idle is suspicious.
- Behavior:: Ansible Runner should only run when triggered by a playbook or CI workflow. Continuous background activity without tasks indicates compromise.
Red Flags: If ansible-runner.exe is located in unusual folders (like Temp, AppData\\Roaming, or System32), runs when no automation is scheduled, has no digital signature, or uses unusual network activity, scan your system with security software. Watch for similarly named files like "ansible-runner.bat" or "ansible-runner.dll" from untrusted sources.
Why Is ansible-runner Running on My PC?
ansible-runner.exe starts when an Ansible playbook is dispatched by a CI system, scheduler, or manual trigger, and may persist while jobs run or until cleanup completes.
Reasons it's running:
- Active Automation Job: A running playbook or a chain of playbooks keeps the runner active to complete tasks.
- CI/CD Integration: A pipeline or workflow triggers ansible-runner as part of automated deployment.
- Scheduled/Recurring Runs: A task in Task Scheduler or an automation platform invokes runner on a schedule.
- Background Inventory Sync: Runner periodically polls inventory and credentials for up-to-date execution.
- Post-run Callbacks: Callbacks to external systems or dashboards keep the runner alive until completion.
Can I Disable or Remove ansible-runner.exe?
Yes, you can disable or remove ansible-runner.exe. It will stop automatic playbook execution, but ensure you don't break any automation workflows that rely on it.
How to Stop ansible-runner.exe
- End Active Runs: Open Task Manager (Ctrl+Shift+Esc), locate 'ansible-runner.exe' and End Task for ongoing jobs.
- Prevent Startup: In Task Manager > Startup tab, disable any entry related to Ansible Runner or CI agents that launch it.
- Stop Background Automation: If used by a service or scheduled task, disable or remove the task or service that launches ansible-runner.
- Graceful Shutdown: If integrated with a controller, trigger a clean stop via the runner CLI (e.g., ansible-runner stop <job_id>) if supported.
- Uninstall: Open Settings > Apps > Apps & Features, select Ansible Runner and Uninstall.
How to Uninstall Ansible Runner
- ✔ Windows Settings → Apps → Apps & Features → Ansible Runner → Uninstall
- ✔ PowerShell: Get-Package -Name 'ansible-runner' | Uninstall-Package -Force
- ✔ If installed via a package manager (e.g., Chocolatey), run: choco uninstall ansible-runner -y
Common Problems: High CPU or Memory Usage
If ansible-runner.exe is consuming excessive resources or behaving unexpectedly, fans or logs may indicate the problem and guide remediation.
Common Causes & Solutions
- Large inventory with many hosts: Split inventory into smaller groups or scope playbooks to a subset of hosts.
- Long-running playbooks: Refactor tasks, enable serial or async execution, or break jobs into smaller runs.
- Inefficient tasks or modules: Replace slow modules, optimize queries, and use batch operations.
- Frequent automatic runs: Adjust schedule, disable non-essential workflows, or throttle concurrency.
- Credential or vault delays: Verify vault configuration and credentials; reduce retry counts.
- Resource constraints: Increase CPU/memory or limit simultaneous runs; optimize host targeting.
Quick Fixes:
1. Open Task Manager and identify active ansible-runner tasks
2. End high-CPU runs or problematic playbooks
3. Update Ansible Runner to the latest version
4. Reduce concurrency by limiting forks or hosts in inventory
5. Review playbooks for inefficient tasks and modules
6. Clear any runner caches or artifacts if applicable
Frequently Asked Questions
Is ansible-runner.exe safe to have on Windows?
Yes, when obtained from the official Ansible/Red Hat channels and located in a legitimate path like C:\\Program Files\\Red Hat\\Ansible Runner\\ansible-runner.exe.
What is Ansible Runner used for?
Ansible Runner provides a reproducible runtime to execute playbooks, manage inventories, credentials, and capture artifacts for automation pipelines.
Can I uninstall Ansible Runner from Windows?
Yes. Uninstall via Settings > Apps, or using your package manager. This will not remove Ansible core code in Ansible Tower/AAP environments, but will remove the runner agent from the machine.
How do I stop ansible-runner from running in the background?
End the ansible-runner.exe process in Task Manager or disable the scheduled/task that triggers it.
Where are Ansible Runner logs and artifacts stored?
Logs are typically written to the runner's artifacts directory or a configured log path; check your runner configuration for specific paths.
How is Ansible Runner different from running ansible-playbook directly?
Ansible Runner provides a consistent runtime, event streaming, and structured artifacts for automation pipelines, whereas ansible-playbook runs may be ad hoc.
