In the previous post, we have seen how to generate multiple files using with_sequence and loop features.
Here, we will introduce the delay functionality in the loop feature. This will give a pause after every iteration. So, each file will be created at specific time interval. The official document on loop control can be found here. Download the .yml file directly if you don’t want to go through the discussion.
Loop and with_sequence allows the commands or the instructions to be executed iteratively. However, I find the syntax bit different from other programming language. Probably this is due to YAML structure. Anyways, lets see few examples and see how to use loop and with_sequence. You can find the official documentation on loop here and on with_sequence here. The list of examples are as follows:
Generate empty file from a list (using with_items) (.yml file)
Generate empty file from a list (using loop)(.yml file)
