ckelner / datadog-ansible-vagrant-terraform

A Vagrant and Terraform config for installing the datadog agent via ansible

Datadog, Ansible, Vagrant, and Terrform

This repo contains two way to create a host with the Datadog agent installed via Ansible; Vagrant and Terraform (leveraging AWS).

Vagrant

• Vagrant
• Ansible
• Vagrant Ansible Provisioner
• Datadog Ansible Role

How to use it

You'll need to either:

• Preferred:
  • Create ./conf.sh file that looks like:

      #!/bin/bash
      DD_API_KEY="<YOURKEYHERE>"
    

    • Where <YOURKEYHERE> is your Datadog API key
  • Run run.sh in place of running vagrant up so that a copy of playbook.yml gets created w/ your API key (ignored by .gitignore)
• Alternative:
  • Copy playbook.yml to playbook_secret.yml (ignored by .gitignore) and modify it to include your API key in place of YOURKEYHERE
  • Run vagrant up as usual

The expected output will look something like:

chriskelner@keldog:~/projects/ckelner/datadog-ansible-vagrant|master⚡
⇒  bash run.sh

Then you can verify the agent is running by:

• vagrant ssh
• sudo /etc/init.d/datadog-agent info

Terraform

• Ansible
• Terraform
• Datadog Ansible Role

How to use it

• Create ./conf.sh file that looks like:

    #!/bin/bash
    DD_API_KEY="<YOURKEYHERE>"
  

  • Where <YOURKEYHERE> is your Datadog API key
• Run bash pb_secret.sh to generate playbook_secret.yml (ignored by .gitignore)
• Run terraform init
• Run terraform plan
• Run terraform apply

Output will look something like:

• sudo /etc/init.d/datadog-agent info
