How to Use Ansible to Fetch Files and Remove Them from Source on Success

Learn how to effectively use `Ansible` to fetch files from Windows nodes to a Linux node, ensuring they are removed from the source if the transfer is successful. --- This video is based on the question https://stackoverflow.com/q/71456247/ asked by the user 'PGEL' ( https://stackoverflow.com/u/16535012/ ) and on the answer https://stackoverflow.com/a/71458414/ provided by the user 'Zeitounator' ( https://stackoverflow.com/u/9401096/ ) at 'Stack Overflow' website.

In this post, we'll address a specific challenge you might face: fetching files from Windows nodes to a Linux server and ensuring that they are deleted from the source once the transfer is successful. The Problem You've set up a process in Ansible to fetch files from Windows nodes, but sometimes, when working with multiple endpoints, file transfers can fail due to various reasons. If any file fails to upload while processing the batch, the entire process for cleaning up (removing fetched files) can be obstructed. This can lead to unnecessary clutter on the source nodes, which is not ideal. The Solution To overcome this issue, we need to refine the playbook to ensure that files are only deleted if they've been successfully fetched. Below, we'll break down the necessary steps for achieving this functionality. Step 1: Find and Register Files First, we'll locate the files we want to fetch using the win_find module from Ansible: [[See Video to Reveal this Text or Code Snippet]] Step 2: Create Destination Directory Next, we need to create a destination directory on the Linux node: [[See Video to Reveal this Text or Code Snippet]] Step 3: Fetch Files Using the fetch module, we’ll transfer the files from the Windows nodes to our Linux host: [[See Video to Reveal this Text or Code Snippet]] Here, we use a loop instead of with_items, which is a more modern option for iteration in Ansible. Step 4: Delete Successfully Fetched Files Finally, we want to clean up the files that were successfully fetched using the file module: [[See Video to Reveal this Text or Code Snippet]] Explanation of Key Modifications Using loop: This replaces with_items and allows better handling of results. We can directly loop through the results stored in fetch_sync, allowing more granular control. Conditional Deletion: By using the select('succeeded') filter, we ensure that only files that were successfully fetched are targeted for deletion. This avoids errors by skipping any files that did not transfer correctly. Conclusion By implementing the steps outlined above, you can efficiently fetch files from Windows nodes and remove them from the source once they've been successfully uploaded. This not only keeps your file system organized but also helps prevent issues with failed transfers clogging your nodes.
