Ansible Playbooks and Roles

From me (@mrlesmithjr) to the community

The goal of this repo is to maintain a consistent configuration across hosts.

This repo will always be updated on a continuous basis and all feedback is encouraged and welcomed.

Master - Main ready to consume branch...May be extremely outdated
Dev - Development branch...Bleeding edge functionality (Initially will be completely different than Master due to redesign)

Requirements

The majority of variables are configurable in group_vars/all
The goal of this is to keep a consistent single place to update site-wide variables.

To ensure all roles are current and up to date you can run the following in the root of this repo..

ansible-galaxy install -r requirements.yml -f -p ./roles --ignore-errors

Playbooks

bootstrap.yml  

Used as phase one of deployments... bootstraps hosts

site.yml

Phase two of deployments... configures base settings and install base packages that should be site-wide

sensu.yml

Installs Sensu Server and Sensu Clients

elkstack_prod.yml

Builds ELKStack Highly Available, Scalable environment

ELKStack - Requirements

Build out the following hosts and modify hosts to reflect name changes...lines with [] define a group name to be added to hosts.
Lines that contain [1:x] are regex values to define multiple hosts.

[elk-p-nodes]
elk-p-haproxy-[1:2]
elk-p-broker-[1:3]
elk-p-es-[1:3]
elk-p-pre-processor-[1:2]
elk-p-processor-[1:4]

[elk-p-haproxy-nodes]
elk-p-haproxy-[1:2]

[elk-p-broker-nodes]
elk-p-broker-[1:3]

[elk-p-es-nodes]
elk-p-es-[1:3]

[elk-p-pre-processor-nodes]
elk-p-pre-processor-[1:2]

[elk-p-processor-nodes]
elk-p-processor-[1:4]

You will need to update group_vars and host_vars to tailor to your environment... Ex. Host naming and etc.

group_vars/all
group_vars/elk-p-broker-nodes
group_vars/elk-p-es-nodes
group_vars/elk-p-haproxy-nodes
group_vars/elk-p-nodes
group_vars/elk-p-pre-processor-nodes
group_vars/elk-p-processor-nodes
host_vars/elk-p-haproxy-1
host_vars/elk-p-haproxy-2
