Value all

The all value is used to simplify the declaration. It is sometimes useful to declare a resource for all target systems or for all its compatible parameters. This avoids having to repeat the declaration for each target system or for each target argument.

all target systems

In cases where the target systems declared in the inventory are all compatible with a resource, you can use the all value to declare compatibility with all target systems.

- source: file.txt
  destination: file.txt
  compatibility:
    - all:
        ...

For this example, the file file.txt is compatible with all target systems declared in the inventory.

all target arguments

In cases where the parameters of a target declared in the inventory are all compatible with a resource, you can use the all value to declare compatibility with all parameters.

- source: file.txt
  destination: file.txt
  compatibility:
    - archi/range/model:
        app: [all]
        envs: [test, dev]

For this example, the file file.txt is compatible with all values of the app parameter of the archi/range/model target.

You could very well declare the file file.txt for each value of the app parameter of the archi/range/model target, but that would be very unreadable if there are many allowed values. Using the all value simplifies the declaration.

Let's continue the example and modify the declaration so that the file file.txt is also compatible with all values of the envs parameter of the archi/range/model target. This would look like:

- source: file.txt
  destination: file.txt
  compatibility:
  - archi/range/model:
      app: [all]
      envs: [all]
