Dotaz: Ansible debconf jak debugovat na Ubuntu 18 LTS

[majales]

Zdravím,

Snažím se pomoci debconf nakonfigurovat balíček při instalaci pomocí ansible. Bohužel se balíček nenakonfiguruje správně (nevytvoří se db a uživatel v db). Jak debugovat co se při debconf děje? Stejná konfigurace mi funguje, když použiji mysql. Při použití mariadb se to ovšem nevykoná.

Balíček je icinga2-ido-mysql Pomocí ansible modulu debconf nakonfiguruji heslo, jměno db, heslo pro administraci:

conf-get-selections |grep icinga2 
icinga2-ido-mysql	icinga2-ido-mysql/mysql/app-pass	password	hesloheslo
icinga2-ido-mysql	icinga2-ido-mysql/mysql/app-password-confirm	password hesloheslo
icinga2-ido-mysql	icinga2-ido-mysql/mysql/admin-pass	password	jineheslo

Pak proběhne instalace balíčku pomocí apt a nic se nestane...

tail /var/log/apt/history.log

Start-Date: 2019-05-22  20:44:52
Commandline: /usr/bin/apt-get -y -o Dpkg::Options::=--force-confdef -o Dpkg::Options::=--force-confold install icinga2-ido-mysql
Requested-By: ansible (1004)
Install: icinga2-ido-mysql:amd64 (2.10.4-1.bionic)
End-Date: 2019-05-22  20:44:52

Nevíte někdo jak zjistit co se tam přesně děje a proč to nevytvoří db a uživatele jak má?

[kolega]

Spustit ten prikaz, co ti to ukazuje? Pripadne si otevri tu roli a mrkni se, co to presne dela, jakymi prikazy moduly a manualne to projdi.

Taky muzes pouzit verbose vystup 'ansible -vvv(vv)'

[majales]

Ansible -vvvv nic zajímavého neukáže.. respektive tam není ani slovo o debconf .. prostě jen OK při instalaci balíčků..

A debconf mas kde? Resp. ako vyzera playbook?

[majales]

Je to role,

tohle je task file kde se konfiguruje debconf.

- name: Debian | server | set debconf configuration
  debconf:
    name: "{{ item.name }}"
    question: "{{ item.question }}"
    value: "{{ item.value }}"
    vtype: "{{ item.vtype }}"
  with_items:
    - { name: 'mysql-server-5.5',
        question: 'mysql-server/root_password',
        value: "{{ icinga2_mysqlrootpw }}",
        vtype: 'password'
      }
    - { name: 'mysql-server-5.5',
        question: 'mysql-server/root_password_again',
        value: "{{ icinga2_mysqlrootpw }}",
        vtype: 'password'
      }
    - { name: 'icinga2-ido-mysql',
        question: 'icinga2-ido-mysql/mysql/admin-pass',
        value: "{{ icinga2_mysqlrootpw }}",
        vtype: 'password'
      }
    - { name: 'icinga2-ido-mysql',
        question: 'icinga2-ido-mysql/db/dbname',
        value: "{{ icinga2_mysqlidodb }}",
        vtype: 'string'
      }
    - { name: 'icinga2-ido-mysql',
        question: 'icinga2-ido-mysql/mysql/app-pass',
        value: "{{ icinga2_mysqlidopass }}",
        vtype: 'password'
      }
    - { name: 'icinga2-ido-mysql',
        question: 'icinga2-ido-mysql/mysql/app-password-confirm',
        value: "{{ icinga2_mysqlidopass }}",
        vtype: 'password'
      }
    - { name: 'icinga2-ido-mysql',
        question: 'icinga2-ido-mysql/enable',
        value: "true",
        vtype: 'boolean'
      }
    - { name: 'icinga2-ido-mysql',
        question: 'icinga2-ido-mysql/mysql/admin-user',
        value: "root",
        vtype: 'string'
      }

Mariadb je nainstalována s debconf

- name: Set MariaDB root password before installing
  debconf: name='mariadb-server' question='mysql-server/root_password' value='{{ icinga2_mysqlrootpw }}' vtype='password'

- name: Confirm MariaDB root password before installing
  debconf: name='mariadb-server' question='mysql-server/root_password_again' value='{{ icinga2_mysqlrootpw }}' vtype='password'

a pak je tam

- name: Debian | Extra packages install
  apt:
    name:
      - icinga2
      - icinga2-ido-mysql
      - git
      - icingaweb2
    state: present
    update_cache: yes
  #  dpkg_options: force-confold
  when: ansible_distribution == 'Ubuntu' and (ansible_architecture == 'i386' or ansible_architecture == 'x86_64')
  register: pkg_result
  until: pkg_result is success

Tak jsem se vykašlal na debconf a vytvořil DB a uživatele "ručně" pomocí ansible..
