Ansible role to unify collections into a single unified collection. Includes a plugin named util and a module named unify.
The items to unify can be single items, collections of items, paths and URLs to .yml files where to load more items.
The variable items is used to specify items to unify, the result is stored on a single unified collection variable. Optionally a secondary unified_b collection will be created if the secondary variable is set to true. If you need more than two unified collections you can use the included unify module.
If the variable expand is set to true or if one item specifies the item_expand attribute as true, the items on each listed file path or URL will be loaded using the variable titles as index, therefore when expanding items from files the variable titles must not be empty.
For example if the value of the items variable is the path /home/username/my-config.yml, the titles variable has the value packages and the expand variable is set to true, this role will try to load a list named packages from the file /home/username/my-config.yml.
The contents of /home/username/my-config.yml could be something like the following:
--- packages: - leafpad - rolldice - /home/username/extra-config.yml - https://my-url/my-config.yml
When the variable expand is set to false, the file paths or URLs found inside the items variable are treated as plain text items, this is useful to maintain files and directories listings, for example for backup purposes.
When adding an item to the unified variable it will be added only if is not already present. On the case of boolean values duplicates are allowed on unified because boolean values are commonly used for checklists.
This role also includes the following functionality:
- Ensure the requirements are installed.
