When starting a new project, use Terraform init to initialize the working directory. This command configures the directory for module and configuration usage. It ensures essential plugins are downloaded and initialized. With this, the project is ready for further configuration and deployment.
Terraform validate
Using Terraform validate, check the validity of the Terraform configuration. This command is a crucial step before deploying changes. It highlights syntax errors or misconfigurations before applying changes. This is a proactive step in catching errors early in the development process.
Terraform plan
Before making any changes to the infrastructure, use the Terraform plan command. It provides a detailed preview of the actions Terraform will take based on the current configuration. can review the proposed changes before applying them, ensuring that the expected modifications align with the desired infrastructure state.
Terraform apply
Once reviewed the proposed changes using Terraform plan and confirmed that everything looks good, proceed with Terraform apply. This command creates or updates infrastructure according to the Terraform configuration. It executes the planned changes and provisions resources as defined in the configuration files.
Terraform get
While working with modules in the root module, use Terraform get to download and update the required modules. This command ensures that the modules are up to date and ready for use within the configuration.
Terraform workspace new
When managing multiple environments or configurations, use Terraform workspace new to create a new workspace. This command helps in segregating different environments and selecting the appropriate workspace for deployment.
Terraform destroy
When it's time to tear down and remove the infrastructure created by Terraform, use Terraform destroy. This command efficiently removes all resources managed by Terraform, allowing me to clean up the environment and free up resources.
Terraform graph
To visualize the dependency graph of the infrastructure and understand the relationships between resources, use the Terraform graph command. This creates a resource graph listing all resources in the configuration and their dependencies, offering a comprehensive overview of the infrastructure setup.

What are Some Best Practices to Adopt for Terraform Automation?
When using Terraform, it is always best to use remote state. This allows for multiple team members to collaborate on the same Terraform configuration. Remote state helps in seeing how changes will impact the infrastructure without the need for local state files.
Leveraging Existing Shared and Community Modules
Shared modules can expedite workflows and reduce the time needed for setup. These modules are usually written by professionals, which means they are production-ready and tested.
Importing Existing Infrastructure
If existing infrastructure is in place, importing it into Terraform is a best practice. It can be less work than rewriting current infrastructure in Terraform.
Avoiding Hard-Coded Variables
Hard-coded variables should be avoided. For example, if a Terraform configuration references an AMI ID, it should not be hardcoded but passed as a variable.
Always Formatting and Validating
Formatting Terraform code and validating it can avoid potential errors. This also ensures that all team members follow a consistent structure.
Implementing a Consistent Naming Convention
Using a naming convention, such as the Terragrunt approach, can make sure that everything is named in a consistent and predictable way.
Tagging Resources
Using tags on resources is beneficial for filtering and identifying resources later on. Tags provide information about a resource, which can be helpful in tracking costs or managing security.
Introducing Policy as Code
Implementing policy as code can help ensure compliance and governance is followed. It adds a layer of security while ensuring configuration drifts are detected early.
Implementing a Secrets Management Strategy
It is highly recommended to incorporate a secrets management strategy. This ensures that sensitive information is handled securely.
Testing Terraform Code
Testing Terraform code is essential to ensure it works as expected. Modules need to be tested independently to validate their behavior.
Enabling Debug/Troubleshooting
Debugging and troubleshooting are essential. These practices are essential for understanding what's wrong when something fails.
Building Modules Wherever Possible
Whenever you can, try to build your configurations in modules. Modularising parts of an infrastructure allows you to reuse and easily test code.
Using Loops and Conditionals
Loops and conditional statements in Terraform code can simplify the configuration. They can also be used to create multiple resources based on one configuration block.
Using Functions
Functions can help make configurations more readable by abstracting complex logic into reusable pieces.
Taking Advantage of Dynamic Blocks
Dynamic blocks are useful when multiple repetitive blocks are needed. They allow for the dynamic creation of blocks of repeated data.
Utilizing Terraform Workspaces
Workspaces allow you to manage separate state files for the same configurations. This can be useful for creating separate environments.
Using the Lifecycle Block
The lifecycle block in Terraform allows for certain configurations to be manipulated to avoid unintended changes. It can help manage the lifecycle of resources.
Utilizing Variables Validations
Validating variables can ensure they meet specific criteria before being passed to the Terraform configuration. This helps prevent errors and unexpected behavior.
Leveraging Helper Tools to Make Your Life Easier
Utilizing helper tools, such as Terragrunt or Terratest, can make your life easier. These tools can streamline workflows and offer additional functionality.
Taking Advantage of the IDE Extensions
IDE extensions can improve productivity and help validate your configurations as you write them. Extensions like Terraform validate can catch errors before they occur.
