Welcome to the new age of development where managing infrastructure is as straightforward as writing code. The T.A.D.S. boilerplate combines the powerful features of Terraform, Ansible, Vagrant, and Docker Swarm to create a comprehensive Infrastructure as Code (IaC) repository. In this guide, we will walk you through the steps of setting it up, ensuring your workflow is brisk and reliable. So, let’s dive in!

What You Will Learn

• How to set up T.A.D.S. from scratch
• Provisioning and deploying environments
• Using Docker Swarm and Ansible effectively
• Troubleshooting common issues

How to Get Started with T.A.D.S.

1. Clone the Repository

First, you need to create your own version of the T.A.D.S. boilerplate. You can do this by cloning the repository:

git clone --single-branch https://github.com/Thomvaill/tads-boilerplate.git YOUR_PROJECT_NAME
cd YOUR_PROJECT_NAME
git remote set-url origin YOUR_REPO_URL
git push

2. Install Required Dependencies

Next, install the dependencies necessary to run T.A.D.S.

.tads install-dependencies

3. Provision Your Local Machine

This step includes copying and editing configuration files:

• Copy ansible/group_vars/localhost_overrides.sample.yml to ansible/group_vars/localhost_overrides.yml.
• Edit it to add your username under the ansible_user variable.
• Provision and deploy using the commands:

.tads ansible-playbook localhost provision
.tads ansible-playbook localhost deploy

4. Write Your Own Docker Swarm Compose Files

Now you can create and customize Docker Swarm Compose files. You’ll use Jinja2 templating to define services efficiently. After customizing the files, make sure to include them in ansible/deploy.yml.

Understanding the T.A.D.S. Workflow: An Analogy

Imagine T.A.D.S. as a chef’s kitchen, where:

• Terraform is the architect designing the kitchen layout—ensuring there’s enough space for all the equipment, from stoves to refrigerators.
• Vagrant acts like the prep cook, creating a temporary workspace to test recipes before presenting them to guests.
• Ansible is the sous-chef, meticulously setting up the equipment and cooking the dishes to perfection, ensuring everything runs smoothly for the chef.
• Docker Swarm serves as the dining area where guests (services) can enjoy perfectly prepared meals (applications), each in its own designated spot for convenience.

With T.A.D.S., all these elements work in sync, allowing for a seamless culinary experience that is easily replicatable elsewhere.

Troubleshooting Common Issues

While using T.A.D.S., you might encounter some hiccups. Here are a few common issues and how to resolve them:

• SSH Errors: Ensure that your SSH key pair is properly configured in your cloud settings. Verify that your VMs accept your SSH keys.
• Docker Not Running: Make sure Docker is installed and running on your local machine. Use the command docker ps to check.
• Provisioning Failures: Double-check your Ansible playbook syntax. You can run ansible-playbook --check for a dry run before actual execution.
• Environment Variables Missing: Ensure you have edited and encrypted the production group_vars files properly. Don’t forget to securely share the encryption key with your team.
