Welcome back to #90DaysOfDevOps! Today, we're rolling up our sleeves to set up our Infrastructure as Code (IaC) environment. Whether you've chosen Terraform, AWS CloudFormation, or Ansible, this is the day to get your tools up and running. I'll guide you through the installation and configuration process, familiarize you with essential resources, and deploy a simple "Hello World" infrastructure to ensure your setup is working.
Installing and Configuring Your IaC Tool
1. Terraform Installation and Configuration
If you've chosen Terraform, follow these steps:
Download the Terraform binary for your operating system from the official website.
Extract the downloaded archive.
Add the Terraform binary to your system's PATH. You can do this by moving it to a directory listed in your PATH or by adding its location to the PATH environment variable.
Verify the installation by running terraform --version.
2. AWS CloudFormation Configuration
AWS CloudFormation doesn't require a separate installation as it's a service provided by AWS. However, you need an AWS account and should configure AWS Command Line Interface (CLI) credentials. Install the AWS CLI if you haven't already:
pip install awscliThen, configure your AWS CLI credentials using:
aws configureFollow the prompts to enter your Access Key ID, Secret Access Key, default region, and output format.
3. Ansible Setup
For Ansible, you might have already set up your environment in a previous blog. If not, you can follow these steps:
1. Install Ansible using your operating system's package manager or a Python package manager like pip.
pip install ansible 2. Create an Ansible configuration file (ansible.cfg) and set your preferred settings.
3. Create an inventory file (hosts) to specify the target hosts for your Ansible playbooks.
Exploring Documentation and Resources
Terraform
For Terraform, explore the official Terraform documentation. The documentation provides detailed explanations and examples of Terraform configurations.
Additionally, join the Terraform community by visiting the Terraform Community page to find forums, GitHub repositories, and other resources.
AWS CloudFormation
Since AWS CloudFormation is an AWS service, you can find comprehensive documentation on the AWS CloudFormation documentation page. It covers everything from getting started to advanced topics.
Explore the AWS forums for community discussions and solutions to common issues.
Ansible
Discover Ansible's capabilities and best practices in the Ansible documentation. It offers detailed guides and examples for various use cases.
Join the Ansible community by visiting the Ansible Community page. Here, you can find forums, blogs, and GitHub repositories.
Deploying a "Hello World" Infrastructure
Now that your environment is set up, let's deploy a simple "Hello World" infrastructure to ensure everything works as expected.
For Terraform, create a Terraform configuration file (e.g., main.tf) with the following content:
resource "null_resource" "hello" {
provisioner "local-exec" {
command = "echo 'Hello, World!'"
}
}Then, run the following commands:
terraform init
terraform applyFor AWS CloudFormation, create a CloudFormation template (e.g., hello-world.yml) with a basic resource like an S3 bucket. You can use the AWS CloudFormation console to create a stack using this template.
For Ansible, create a simple Ansible playbook (e.g., hello-world.yml) that runs a "Hello, World!" command on your target hosts. Run the playbook using the ansible-playbook command.
Congratulations! You've successfully set up your IaC environment, explored documentation and resources, and deployed a basic infrastructure. This marks the beginning of your hands-on journey with Infrastructure as Code.
As you continue your #90DaysOfDevOps challenge, remember that practice and exploration are key. Experiment with more complex infrastructures and scenarios to deepen your understanding of your chosen IaC tool.
With this, let's wrap this post here.
Thank you for reading!
