To avoid deleting my entire home directory by accident, I ran my first attempt with the -check option. This playbook must have been written by someone who really knows and loves YAML! Testing Ansible plays safely Verify that your YAML is correct using the yamllint command: $ yamllint cleanup.yaml Verify the playbookĪnsible playbooks are written in YAML, which has a strict syntax. If you get this step wrong, you can easily remove files you don't intend to delete. This is a very dangerous step, especially during testing. Once the current item's path is extracted, Ansible uses the state: absent rule to ensure that the file located at that path is not left on the system (in other words, it's deleted.) The with_items step uses the contents of the result variable to extract one filename at a time, which becomes the item for the path parameter. The variable has no information on the path until the file module is used in a loop by the with_items keyword. The path parameter uses the built-in "" variable, which confusingly isn't actually defined yet. This step relies entirely on the find step, so it uses several variables: - name: Remove CSV files The module used to remove files is the file module. The next step in the task is to remove the files that find has uncovered. This is important because I want Ansible to perform a second action on the results of find, so those results need to be stored somewhere for the next step. The finishing touch to this step is to invoke the register module, which saves the results of the find process into a variable called result. csv, but I'm confident that I'm willing to remove. The patterns parameter tells Ansible what to count as a match. Ansible only targets the CSV files I save straight to Downloads (which is my habit). This gives me the ability to retain CSV files that I've downloaded and saved into a subdirectory. The recurse: false parameter forbids Ansible from searching in subdirectories of Downloads. The paths parameter tells Ansible where to search for files. Here's how to find CSV files in Downloads with Ansible:. But they hang around for weeks until I get overwhelmed and delete them. They get downloaded weekly, processed, and then ought to disappear. In my case, the files I accidentally collect in my Downloads folder are CSV files. This is my process when I start writing a playbook: I find a module in the Ansible module index that seems likely to do what I need, and then I read through its parameters to find out what kind of control I have over the module. In this example playbook, I want to find files explicitly located in the ~/Downloads folder and I can define that using the paths parameter. If an Ansible module is a command, its parameters are its command options. You can locate files on a system using the find Ansible module. Once you have those lines in a text file, you can start defining the steps in your task. They're the "shebang" ( #!) of Ansible playbooks. Ansible boilerplateĪnsible playbooks generally start in exactly the same way: Define your hosts and announce a task: -Ĭommit those three lines to memory. I decided to use a highly specific Ansible task to find files I know I don't need and then remove them. However, there are other files that I download expressly to use once and then ought to remove. There have been times when I realize I still need a file in my Downloads folder, so forgetting about a file rather than promptly removing it can be helpful. On the one hand, I don't mind this habit. If you're like me, you end up downloading many files from the Internet throughout the day and then forget that the files exist. One of the tasks I recently assigned to Ansible was the monumental one of keeping my Downloads folder tidy.
