Title: Debian updates with Ansible Date: 2016-01-31 Category: Ansible Playbook
I've recently bought a HP Proliant Microserver Gen8 to play around with LXC and try new stuff.
From the 4 Debian machines I had to keep up-to-date, I now have 7, so it became quite time-consumming to manually SSH to each of them whenever an update became available.
I ended up looking at Ansible to speed up the process and, within an hour, I had a working playbook that updates the debian packages, pip packages and git repos installed on all of my servers with a single command.
I figured I'd share the playbook I use to update the Debian packages !
The playbook
I modified this gist to only use apt-get instead of both apt-get and aptitude.
- hosts: all
tasks:
- name: update cache
apt: update_cache=yes
- name: list packages to upgrade (1/2)
shell: apt-get upgrade -s -V | awk '/=>/{print $1}'
register: updates
changed_when: False
- name: list packages to upgrade (2/2)
debug: msg="{{ updates.stdout_lines | count }} packages to upgrade ({{ updates.stdout_lines | join(', ') }})"
when: (updates.stdout_lines)
- name: upgrade packages
apt: upgrade=dist
when: (updates.stdout_lines)
- name: check what the new version is
shell: lsb_release -r | awk '{print $2}'
changed_when: False
register: new_release
- name: notify distribution version upgrade
debug: msg="Debian has been upgraded from {{ ansible_lsb.release }} to {{ new_release.stdout }}"
when: ansible_lsb.release != new_release.stdout
- name: /wheezy/ install the debian-goodies package if it is missing
apt: name=debian-goodies state=present
when: ansible_distribution_release == 'wheezy'
- name: /jessie/ install the needrestart package if it is missing
apt: name=needrestart state=present default_release=jessie-backports
when: ansible_distribution_release == 'jessie'
- name: /wheezy/ list services to restart (1/3)
shell: checkrestart | awk '/^service/{print $2}'
register: wheezy_services
changed_when: False
when: ansible_distribution_release == 'wheezy'
- name: /jessie/ list services to restart (1/3)
shell: needrestart -bl | awk '/^NEEDRESTART-SVC/{print $2}'
register: jessie_services
changed_when: False
when: ansible_distribution_release != 'wheezy'
- name: merge services list (2/3)
set_fact:
services: "{{ wheezy_services if ansible_distribution_release == 'wheezy' else jessie_services }}"
- name: list services to restart (3/3)
debug: msg="{{ services.stdout_lines | count }} services to restart ({{ services.stdout_lines | join (', ') }})"
when: (services.stdout_lines)
- name: cache cleanup
shell: apt-get autoclean
