the dir parameter for calling roles

问题

I've got this bit in my playbook.

 roles:
  - {role: cleanup-create, dir: '/standard/', commit: "{{choice}}"}

The file structure is /roles/standard/cleanup-create/tasks/main.yml

And yet I receive this error:

ERROR! the role 'cleanup-create' was not found in /home/myuser/network-ansible-myuser/roles:/home/myuser/network-ansible-myuser:/etc/ansible/roles

The error appears to have been in '/home/myuser/network-ansible-myuser/configure-files.yml': line 15, column 5, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

  roles:
  - {role: cleanup-create, dir: '/standard', commit: "{{choice}}"}
    ^ here

Now, the error message seems to be saying my role wasn't found in /roles. However the dir parameter should make it look under /roles/standard.

It was working 5 minutes ago, I swear!

回答1:

There is no dir special parameter for roles.
It is just an ordinary variable, same as commit in your example.

You should place all your roles directly in ./roles folder without any nesting.

回答2:

You can actually set roles_path configuration variable in ansible.cfg (or maybe pass it in the command line - try it, I'm not sure if you can do this with roles_path).

From the doc:

The roles path indicate additional directories beyond the roles/ subdirectory of a playbook project to search to find Ansible roles

./roles from playbook directory will be searched first, then additional paths will be checked.

You can specify multiple directories to look for roles in

roles_path=/var/opt/my_roles:/var/opt/more_roles
