Terraform automates infrastructure provisioning by defining configuration in code.

• Terraform reads configuration files written in HashiCorp Configuration Language (HCL)

• It creates an execution plan to determine what actions are necessary to achieve the desired state

• Terraform then executes the plan to build the infrastructure

• It tracks the state of the infrastructure and can make changes as needed

• Terraform supports various

Establishing a scalable Argo CD architecture for multiple environments with minimal effort.

• Utilize Argo CD Applications to manage configurations for different environments

• Leverage Argo CD Projects to group related applications and manage access control

• Implement GitOps principles to automate deployment workflows and ensure consistency

• Use Helm charts to define application dependencies and simplify deployment configuratio

Terraform Metaarguments are used to modify the behavior of resources in different scenarios.

• Metaarguments can be used to control how Terraform handles resources, such as count, depends_on, lifecycle, provider, etc.

• They can be used to define dependencies between resources, manage resource creation and deletion, and specify resource behavior.

• Metaarguments can be used in various scenarios like defining resource dependenci...read more

Terraform can manage multiple environments without using workspaces by utilizing composite modules.

• Use composite modules to define reusable components that can be shared across multiple environments.

• Leverage variables and input parameters to customize the behavior of the composite modules for each environment.

• Organize the infrastructure code in a modular and scalable way to easily manage multiple environments.

• Avoid usi...read more

Creating composite Terraform modules and passing values to other modules.

• Create a main module that calls other modules

• Define input variables in the main module and pass them to the child modules

• Use output variables in the child modules to return values to the main module

• Example: main.tf calls moduleA and moduleB, passing variables and using outputs
