Common

Ansible role containing some common server config tasks.

Set the hostname
Set the timezone
Set resolving nameservers (optional)
Install some packages (optional)
Add custom group(s) (optional)
Configure sudoers for custom group(s) (optional)
Add user(s) (optional)

Current version is build for and tested on CentOS 7. Though apart from installing the Epel repository (which is wrapped in an ansible_distribution conditional) I don't see a reason why this role should not also work for Ubuntu/Debian, really.

Role variables

common_hostname

The variable name should be self-explanatory.
Default: Extracts value from {{ inventory_hostname }}

common_timezone

The variable name should be self-explanatory.
Default: Europe/Amsterdam

common_resolvers

A dictionary containing containing a primary and secondary resolving nameserver for your server. If not set or only 1 nameserver is given nothing will happen. Example below uses Google's public DNS servers

---
common_resolvers:
  primary: { addr: '8.8.8.8'}
  secondary: { addr: '8.8.4.4'}

common_packages

A list of packages and their state. Packages should be in standard repo or Epel and require no additional configuration. Some good examples are Vim, Tmux, Fish, Git, etc..

---
common_packages:
  - { name: 'vim', state: 'present' }
  - { name: 'tmux', state: 'present' }

common_groups

A list of groups to be added and optionally their respective sudoers entry.

---
common_groups:
  - { name: 'superheroes', state: 'present', sudoers: 'ALL=(ALL) NOPASSWD: ALL' }
  - { name: 'sidekicks', state: 'present', sudoers: 'ALL=(ALL:ALL)' }
  - { name: 'minions', state: 'present' }
  - { name: 'villains', state: 'absent' }

common_users

A list of per-user dictionaries containing the following:

user name (required)
state (required)
additional groups
default shell
ssh_authorized_key

The shell defaults to '/bin/bash'. If you specify an alternative one here, don't forget to make sure it's present by using common_packages.

---
common_users:
  - { name: 'batman', state: 'present', groups: 'superheroes', shell: '/usr/bin/fish', sshkey: 'https://m4rcu5.keybase.pub/.ssh/marcus.pub' }
  - { name: 'robin', state: 'present', groups: 'sidekicks', sshkey: 'robinspublicsshkeyasastring' }
