Ansible/Yeti

Walkthrough of creating an Ansible playbook for yeti.

a) found pyenv playbook online. use this.

b) flailing with vagrant.

Setup

Before we start, we want to have the following:

• repository where our playbook will go (https://github.com/charlesreid1/dahak-yeti)
• Vagrantfile for running vagrant machines for testing our playbook

Vagrantfile

Here we give a Vagrantfile that will start three separate nodes. This is important to test yeti's ability to handle multiple machines.

Vagrantfile:

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|

  # Use the same key for each machine
  config.ssh.insert_key = false

  config.vm.define "vagrant1" do |vagrant1|
    vagrant1.vm.box = "ubuntu/xenial64"
    vagrant1.vm.network "forwarded_port", guest: 80, host: 8877
    vagrant1.vm.network "forwarded_port", guest: 443, host: 7443
  end
  config.vm.define "vagrant2" do |vagrant2|
    vagrant2.vm.box = "ubuntu/xenial64"
    vagrant2.vm.network "forwarded_port", guest: 80, host: 8878
    vagrant2.vm.network "forwarded_port", guest: 443, host: 7444
  end
  config.vm.define "vagrant3" do |vagrant3|
    vagrant3.vm.box = "ubuntu/xenial64"
    vagrant3.vm.network "forwarded_port", guest: 80, host: 8879
    vagrant3.vm.network "forwarded_port", guest: 443, host: 7445
  end
end

Inventory file

Info for the inventory file (port numbers) can be obtained with:

vagrant ssh-config

The corresponding inventory file looks like this:

[servers]
vagrant1 ansible_host=127.0.0.1 ansible_port=2222
vagrant2 ansible_host=127.0.0.1 ansible_port=2201
vagrant3 ansible_host=127.0.0.1 ansible_port=2202
