Title: Debian updates with Ansible
|
|
Date: 2016-01-31
|
|
Category: Ansible Playbook
|
|
|
|
I've recently bought a [HP Proliant Microserver Gen8](http://www8.hp.com/us/en/products/proliant-servers/product-detail.html?oid=5379860) 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](http://www.ansible.com/) 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](https://gist.github.com/maethor/380676f6b1cec8cc7439) to only use apt-get instead of both apt-get and aptitude.
|
|
|
|
```yaml
|
|
- hosts: debian
|
|
remote_user: admin
|
|
become: yes
|
|
become_method: sudo
|
|
tasks:
|
|
- name: update cache
|
|
apt: update_cache=yes
|
|
- name: list packages to upgrade (1/2)
|
|
shell: apt-get upgrade --show-upgraded --assume-no | grep -A1 'The following packages will be upgraded:' | sed '1d;s/ //;s/ /\n/g'
|
|
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 (1/2)
|
|
shell: checkrestart | grep ^service | awk '{print $2}'
|
|
register: services
|
|
changed_when: False
|
|
when: ansible_distribution_release == 'wheezy'
|
|
- name: /jessie/ list services to restart (1/2)
|
|
shell: needrestart -bl | grep ^NEEDRESTART-SVC | awk '{print $2}'
|
|
register: services
|
|
changed_when: False
|
|
when: ansible_distribution_release != 'wheezy'
|
|
- name: list services to restart (2/2)
|
|
debug: msg="{{ services.stdout_lines | count }} services to restart ({{ services.stdout_lines | join (', ') }})"
|
|
when: (services.stdout_lines)
|
|
- name: cache cleanup
|
|
shell: apt-get autoclean
|
|
```
|
|
|
|
