Minimum Viable Sensu with Vagrant

Requirements.md

In order to complete the Minimum Viable Sensu workshop on your own computer, please install the following:

• VirtualBox
• Vagrant
• Vagrantfile provided in this gist
• Centos 7.3 Vagrant box -- should be downloaded automatically

With these applications installed, and the Vagrantfile copied an otherwise empty directory, run vagrant up to download the required Vagrant box and start the VM.

Once the box file is downloaded and the VM is running, use vagrant ssh to log in to the VM via ssh.

Steps.sh

# Make sure we have all the package repos we need!
$ sudo yum install epel-release -y
# Set up Sensu's repository
$ echo '[sensu]
name=sensu
baseurl=https://repositories.sensuapp.org/yum/$releasever/$basearch/
gpgcheck=0
enabled=1' | sudo tee /etc/yum.repos.d/sensu.repo
# Get Redis installed and started
$ sudo yum install redis -y
$ sudo systemctl start redis.service
# Install Sensu itself
$ sudo yum install sensu -y
# Provide minimal transport configuration (used by client, server and API)
$ echo '{
  "transport": {
    "name": "redis"
  }
}' | sudo tee /etc/sensu/config.json
# provide minimal client configuration
$ echo '{
 "client": {
   "environment": "development",
   "subscriptions": [
     "dev"
   ]
 }
}' |sudo tee /etc/sensu/conf.d/client.json
# Ensure config file permissions are correct
$ sudo chown -R sensu:sensu /etc/sensu
# Start Sensu server, API and client services
$ sudo systemctl start sensu-{server,api,client}.service
# Install curl and jq helper utilities
$ sudo yum install curl jq -y
# Use curl to query the API, verify that the client has registered
$ curl -s http://127.0.0.1:4567/clients | jq .

Vagrantfile

Vagrant.configure("2") do |config|
  config.vm.box = "bento/centos-7.3"

  config.vm.network "forwarded_port", guest: 3000, host: 3000
  config.vm.network "forwarded_port", guest: 4567, host: 4567

  config.vm.provider "virtualbox" do |vb|
    # Display the VirtualBox GUI when booting the machine
    # vb.gui = true
    # Customize the amount of memory on the VM:
    vb.memory = "1024"
  end
end

Wondering if it would be worth it to add a sudo yum group install "Development Tools" in the script if we're going to be adding any plugins during the demo/training. As it stands, that has to be installed for any plugins installed via sensu-install -p.
