#Terraform #cheatsheet covering key concepts and common commands
### Terraform Basics: ###
1. **Installation**:
- Download Terraform from the [official website](https://www.terraform.io/downloads.html).
- Install Terraform on your system.
2. **Initialization**:
- `terraform init`: Initializes a new or existing Terraform working directory, downloading any necessary providers and modules.
3. **Configuration**:
- Create a `.tf` file to define infrastructure as code (IaC) using HashiCorp Configuration Language (HCL).
### Terraform CLI Commands:
4. **Plan**:
- `terraform plan`: Generates an execution plan, displaying changes that will be made to infrastructure without applying them.
5. **Apply**:
- `terraform apply`: Applies the changes defined in the configuration, creating or updating infrastructure.
6. **Destroy**:
- `terraform destroy`: Destroys the resources defined in the configuration.
7. **Workspace**:
- `terraform workspace new <name>`: Creates a new workspace.
- `terraform workspace list`: Lists available workspaces.
- `terraform workspace select <name>`: Switches to a different workspace.
- `terraform workspace delete <name>`: Deletes a workspace.
8. **State Management**:
- `terraform state list`: Lists resources in the Terraform state.
- `terraform state show <resource>`: Displays details of a specific resource in the state.
- `terraform state rm <resource>`: Removes a resource from the state.
9. **Variables**:
- Define input variables in `.tf` files or use variable files.
- `-var` or `-var-file` flags to specify variable values.
### Terraform Configuration:
10. **Providers**:
- Define cloud or infrastructure providers (e.g., AWS, Azure, GCP) in the configuration.
11. **Resources**:
- Define resources (e.g., VMs, networks) to create or manage.
- Use resource blocks like `resource "aws_instance" "example" { ... }`.
12. **Modules**:
- Organize and reuse configurations using modules.
- Include modules using `module` blocks.
13. **Data Sources**:
- Fetch information from providers without creating resources.
- Use data blocks like `data "aws_ami" "example" { ... }`.
14. **Outputs**:
- Define values to be shown when `terraform apply` is executed.
- Use output blocks like `output "instance_ip" { ... }`.
15. **Variables**:
- Declare input variables using variable blocks.
- Use variables in resource and module configurations.
### Terraform State and Backends:
16. **State File**:
- Terraform stores its state in a file named `terraform.tfstate` by default.
17. **Remote State**:
- Use remote backends (e.g., AWS S3, Azure Storage) for state storage.
- Configure remote backends in the configuration.
### Best Practices:
18. **Code Structure**:
- Organize Terraform configurations into modular and reusable components.
- Use folders and modules for better organization.
19. **Variables and Outputs**:
- Use variables and outputs for flexibility and readability.
- Define default values and descriptions for variables.
20. **Documentation**:
- Add comments and documentation to your Terraform code.
21. **Versioning**:
- Specify a required Terraform version in the configuration.
- Use version constraints in `provider` blocks.
22. **Environment Variables**:
- Use environment variables (e.g., `TF_VAR_name`) to set variable values.
- Environment variables take precedence over default values.
23. **Sensitive Data**:
- Avoid storing sensitive data (e.g., secrets) directly in Terraform code.
- Use environment variables or external secret management tools.
This Terraform cheat sheet provides a solid foundation for managing infrastructure as code using Terraform. Be sure to refer to the official Terraform documentation for more in-depth information and best practices.
