How to improve Ansible YAML error output - 분석맨의 '두 번째 뇌'

Are you struggling with deciphering errors while writing YAML in Ansible? A simple tweak in your Ansible configuration can vastly improve your error troubleshooting process. In this post, I'll guide you through the steps to modify your Ansible configuration for better error visibility. You can see how the Before and After have changed as shown below. ### Before ![[ansible-stdout-debug_before.jpg]] ### After ![[ansible-stdout-debug_after.jpg]] ## **Step 1: Accessing the Ansible Configuration File** First, you need to access the Ansible configuration file. This file is typically located at `/etc/ansible/ansible.cfg`. To edit this file, use a text editor like `vi`. Here’s how you can open it: ``` sudo vi /etc/ansible/ansible.cfg ``` Using `sudo` is essential because the configuration file requires administrative privileges for modifications. ## **Step 2: Modifying the stdout_callback Option** Once you have the configuration file open in `vi`, you're looking to modify the `stdout_callback` option. By default, this might be set to `skippy`. The `skippy` setting is useful for skipping over tasks that don’t have any changes, but it can be less informative when you’re trying to debug. You'll change this to `debug` to get more detailed output, especially useful for troubleshooting YAML syntax and runtime errors. Locate the line that looks like this: ``` stdout_callback = skippy ``` or ``` stdout_callback = default ``` Change it to: ``` stdout_callback = debug ``` If you can't find this line, you might need to add it under the `[defaults]` section. ## **Step 3: Saving the Changes** After making the change, save your modifications. In `vi`, you can do this by pressing `Esc`, typing `:wq`, and then pressing `Enter`. This command writes the changes to the file and quits the editor. ## **Step 4: Testing the New Configuration** To ensure your changes are effective, run an Ansible playbook. You should now see more detailed output when errors occur, making it easier to identify and fix any issues in your YAML syntax or other Ansible-related errors. Remember, detailed debug output can be quite verbose, so it’s a good idea to use this setting primarily for debugging purposes. ## **Conclusion** Enhancing error visibility in Ansible is as simple as changing one line in the configuration file. This small change can save you a significant amount of time in debugging and ensure a smoother automation experience with Ansible. Happy automating! ## Links [[_MOC_2_Network]]
