Getting started

Example inventory

To enable the nscd service on a host, you need to add it to the [debops_service_nscd] Ansible inventory group.


A common case is configuration of LDAP authentication in the entire cluster of hosts. You can enable debops.nscd role on all DebOps hosts in the Ansible inventory at once:



The nscd service can also be installed and configured by other playbooks, for example bootstrap-ldap.yml. In such cases the custom playbook will configure the nscd service on a host, but the role playbook will not work on a host automatically; you will have to include that host in the [debops_service_nscd] Ansible inventory group via one of the methods above to be able to change the service configuration.

Example playbook

If you are using this role without DebOps, here's an example Ansible playbook that uses the debops.nscd role:


- name: Manage Name Service Cache Daemon
  collections: [ 'debops.debops', 'debops.roles01',
                 'debops.roles02', 'debops.roles03' ]
  hosts: [ 'debops_service_nscd' ]
  become: True

  environment: '{{ inventory__environment | d({})
                   | combine(inventory__group_environment | d({}))
                   | combine(inventory__host_environment  | d({})) }}'


    - role: nscd
      tags: [ 'role::nscd', 'skip::nscd' ]

Ansible tags

You can use Ansible --tags or --skip-tags parameters to limit what tasks are performed during Ansible run. This can be used after host is first configured to speed up playbook execution, when you are sure that most of the configuration has not been changed.

Available role tags:

Main role tag, should be used in the playbook to execute all of the role tasks as well as role dependencies.
