Write --> Init --> Plan --> Apply --> Destroy
a. Write
Write or modify the code to create and change the infrastructure.
b. Init
Download and install the required plugins and providers according to the terraform code present in a current directory.
c. Plan
Review and dry run the planned architecture before applying on the actual environment.
d. Apply
Accept the changes and implement them in actual environment.
e. Destroy
Remove or destroy all the infrastructure that were made by the Terraform.
These are the basic commands used in Terraform Administration.
terraform init
It initiates a terraform plugin required by the infra code.
terraform plan
To show the changes that will be made to the cloud after apply.
terraform validate
Check if the configurations made are proper or not.
terraform apply
Applies the configuration to the cloud.
terraform distroy
Distroy the configuration made in cloud
terraform refresh
Refresh the configuration in tfstate file with the actual environment.
terraform show
Shows the content of tfstate file
terraform output
Prints the configured output results.
terraform console
It takes into the terraform command line.
terraform fmt
It makes the terraform code aligned and indented.
terraform taint <resource-type> <resource-name>
It marks the resource as a taint and replaces it in next apply instead of updating it.
Note: Terraform do not recomends the taint command, use "terraform apply --replace" instead.
