[英]Puppet and hiera,how to apply changes?
我想通過 puppet 更新 cron。 直到今天,我只使用工頭申請,從未使用過 hiera。 在此之后HOWTO首先我必須創造hiera迪爾斯
cd /etc/puppet && mkdir -p hieradata/development hieradata/production/domains hieradata/production/fqdns hieradata/production/OBSOLETE hieradata/production/roles
然后我編輯 hiera.yaml
:backends:
- yaml :yaml: :datadir: '/etc/puppet/hieradata/%{::environment}' :hierarchy:
- fqdns/%{::fqdn}
- roles/%{::role}
- domains/%{::domain}
- common
然后我放入 common.yaml
## Cron module
cron::enable: true # on startup
cron::ensure: true # running
cron::crontab_path: /etc/crontab
puppetheader: Managed by Puppet @ site.priv
cron::crontab_vars_hsh:
SHELL: /usr/bin/sh
PATH: /sbin:/bin:/usr/sbin:/usr/bin
MAILTO: ""
HOME: /root
cron::crontab_site_job_hsh:
'check scripts in cron.hourly, cron.daily, cron.weekly and cron.monthly':
- "*/35 * * * * script.sh >/dev/null 2>&1"
希拉似乎工作
hiera -c ../hiera.yaml cron::ensure
hiera cron::ensure
true
但是在 puppet agent -t... 之后沒有任何變化並且 /etc/crontab 是系統默認值。 我也做過
puppet apply -e 'include cron' --hiera_config=/etc/puppet/hiera.yaml --verbose --debug
並返回
Debug: Scope(Class[Cron::Crontab::Config]): Retrieving template cron/crontab.erb

我想念什么?
編輯 1:我添加了 .erb
## <%= puppetheader %>
# for <%= package_name %>
<% if (!crontab_vars_hsh.empty?) -%>
## Variables
<% crontab_vars_hsh.sort.each do |key,val| -%>
<%= key %>=<%= val %>
<% end -%>
<% end -%>
# Example of job definition:
# .---------------- minute (0 - 59)
# | .------------- hour (0 - 23)
# | | .---------- day of month (1 - 31)
# | | | .------- month (1 - 12) OR jan,feb,mar,apr ...
# | | | | .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
# | | | | |
# * * * * * username command-to-be-executed
<% if (!crontab_site_job_hsh.empty?) -%>
## Site Wide Jobs
<% crontab_site_job_hsh.sort.each do |key,val| -%>
# <%= key %>
<% val.each do |croncmd| -%>
<%= croncmd %>
<% end -%>
<% end -%>
<% end -%>
<% if (!crontab_node_job_hsh.empty?) -%>
## Node Specific Jobs
<% crontab_node_job_hsh.sort.each do |key,val| -%>
# <%= key %>
<% val.each do |croncmd| -%>
<%= croncmd %>
<% end -%>
<% end -%>
<% end -%>
定時任務類型
cron是 Puppet 5 之前的 Puppet 通用類型,無需安裝特殊模塊。 對於 Puppet 6 及更高版本,需要cron_core
模塊(資源已移至外部模塊),例如
puppet module install puppetlabs-cron_core
用法應該是一樣的。
cron { 'myscript':
command => '/usr/bin/python myscript.py',
user => 'root',
minute => '30',
hour => '0',
}
如果要使用 Hiera yaml,請聲明一些作業
cron_jobs:
'myscript':
command: 'm/usr/bin/python myscript.py'
minute: 30
hour: 0
date: '*'
month: '*'
weekday: '*'
user: root
在木偶代碼中:
create_resources (cron, lookup('cron_jobs', Hash, undef, {}))
定時模塊
cron
模塊內部不使用 Puppet 的cron
類型,它直接管理磁盤上的配置文件。 因此 API 可能略有不同:
---
cron::job:
'myscript':
command: 'm/usr/bin/python myscript.py'
minute: 30
hour: 0
date: '*'
month: '*'
weekday: '*'
user: root
並且不要忘記在節點定義的某處添加include cron
。
