Get time back, update all your Linux distribution in one command line

Easy peasy, let's use Ansible to make the work for us !

To install Ansible, take a peek at our earlier post right here.
Create your inventory host file with the list of your Linux :

[linux]
10.0.4.26
10.0.4.28
10.0.4.6
10.0.4.63
10.0.4.49
10.0.4.3
10.0.5.135

[pihole]
192.168.1.253
10.0.5.146

[proxmox]
10.0.5.130
10.0.5.131
10.0.5.132

[deployacronis]
10.0.4.64
10.0.4.36

Then whip up your new playbook using the YAML file below :

- hosts: all
  become: yes
  tasks:
    # This task updates servers that use 'yum' and RPM packages
     - name: .rpm upgrade server
      yum: >
        update_cache=yes
        name=*
        state=latest
        update_cache=yes
      when: >
        ansible_distribution == 'CentOS'
        or
        ansible_distribution == 'RedHat'

    # This task updates servers that use 'apt' and DEB packages
    - name: .deb do safe-upgrade
      apt: >
        update_cache=yes
        cache_valid_time=1200
        upgrade=safe
      when: >
        ansible_distribution == 'Debian'
        or
        ansible_distribution == 'Ubuntu'

the playbook apply to all by the <hosts: all> at line 1.
How about a more selective approach? Something like <hosts: "deployacronis">

Then off you go, Ansible, my trusty minion—handle the work for me!

sudo ansible-playbook playbooks/update-linux.yml --key-file "/home/greg/ansible/id_rsa" --user=greg --ask-become-pass --ssh-common-args='-o StrictHostKeyChecking=no'
