The snippets are organized within topic-labeled folders. 'plates' is short-hand for templates, and houses all folders / projects that can be copied and edited / adjusted locally as templates for larger projects.

Requirements
|
||||
------------
|
||||
|
||||
Any pre-requisites that may not be covered by Ansible itself or the role should be mentioned here. For instance, if the role uses the EC2 module, it may be a good idea to mention in this section that the boto package is required.
|
||||
Expects that the host is using apt package manager, and running a Debian / Ubuntu system.

Role Variables

--------------
|
||||
|
||||
A description of the settable variables for this role should go here, including any variables that are in defaults/main.yml, vars/main.yml, and any variables that can/should be set via parameters to the role. Any variables that are read from other roles and/or the global scope (ie. hostvars, group vars, etc.) should be mentioned here as well.
|
||||
Found in `.../roles/core/defaults/main.yml`
|
||||

Example Playbook
|
||||
----------------
|
||||
|
||||
Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:
|
||||
After configuring the appropriate variables in `.../defaults/main.yml`, create the following play.yml and run `ansible-playbook play.yml` after setting the correct hosts in your `/etc/ansible/hosts` file.
|
||||
|
||||
- hosts: servers

|
|||
|
||||
Never run a script you can't read or understand. Comments can be found in the scripts, usually explaining them block-by-block. Below is my personal use cases for the scripts, to provide further insight into how I use them and how they might be useful to you.
|
||||
|
||||
#### adduser.sh
|
||||
|
||||
This script was made on Ubuntu when creating a few users across multiple hosts. Syntax requires at least 2 arguments when running the script, otherwise help text will be output warning of correct usage and available options. The script can be used to configure sudo on a new user if the script itself is ran with sudo. Otherwise, creating a default user with or without a password is possible without sudo. If the script is ran on an existing user or a userID that is already in use is passed, no changes will happen in user-creation but you may still allow the user to sudo and change their password.
|
||||
|
||||
Syntax -
|
||||
|
||||
./adduser (Help text)
|
||||
./adduser jeff 1005 (Create user jeff with userID 1005, can't configure sudo, prompt for possible password creation)
|
||||
|
||||
sudo ./adduser (Help text)
|
||||
sudo ./adduser jeffy 1010 (Create user jeffy with userID 1010, can configure sudo, possible password creation)
|
||||
|
||||
Didn't configure sudo, and don't want to do so manually? Re-run the script on the existing user just as above, and accept the prompt for sudo configuration.
|
||||
sudo ./adduser jeff 1005 (User creation will fail, follow prompts to configure sudo and / or reset user password)
|
||||
|
||||
#### cmake-build.sh
|
||||
|
||||
I usually run this script within whatever directory I'm working in, hence the infinite loop, I leave the script running until I'm done with my work and move to a new directory / cmake project.
