How would you separate role executions and avoid dependencies between roles in Ansible?

To separate role runs in Ansible and avoid dependencies between roles, you can use the following approaches:

• Use separate playbooks for each role. This way, roles are executed independently, and you can control their order externally.

• Use import_role or include_role with the apply parameter in the appropriate places in the playbook to explicitly manage the order and isolation of roles.

• Avoid passing variables directly between roles. It's better to use common variables at the playbook level or use Ansible facts for data exchange.

• Use tags (tags) to run specific roles or tasks separately.

• Organize roles so that they are as independent as possible and do not require results from each other.

• If roles need to interact, use external synchronization mechanisms, such as flag files or Ansible Vault for storing state.

Thus, roles become modular and can be run independently, which simplifies maintenance and scaling of the infrastructure.
