Getting started¶
Default configuration¶
The sysfs
configuration will not be applied by default in a container
environment (LXC, OpenVZ), since these environments usually have the /sys
filesystem mounted read-only. You can control this using the
sysfs__enabled
variable.
Example inventory¶
To configure the /sys
kernel filesystem on a host by the debops.sysfs
role, that host needs to be added to the [debops_service_sysfs]
Ansible
inventory group:
[debops_service_sysfs]
hostname
Example playbook¶
If you are using this role without DebOps, here's an example Ansible playbook
that uses the debops.sysfs
role:
---
- name: Configure sysfs options
collections: [ 'debops.debops', 'debops.roles01',
'debops.roles02', 'debops.roles03' ]
hosts: [ 'debops_service_sysfs' ]
become: True
environment: '{{ inventory__environment | d({})
| combine(inventory__group_environment | d({}))
| combine(inventory__host_environment | d({})) }}'
pre_tasks:
- name: Prepare sysfs environment
import_role:
name: 'sysfs'
tasks_from: 'main_env'
tags: [ 'role::sysfs', 'role::secret' ]
roles:
- role: secret
tags: [ 'role::secret', 'role::sysfs' ]
secret__directories:
- '{{ sysfs__secret__directories | d([]) }}'
- role: sysfs
tags: [ 'role::sysfs', 'skip::sysfs' ]
