Terraform Cheatsheet
#Initializes the working directory that contains our terraform code
$ terraform init
** Generally it downloads the modules and plugins and sets up the backend for storing terraform state file (by which terraform keeps tracks of resource).
#to check what changes will take place once terraform is applied
$ terraform plan
Terraform plan generally reads the code & then creates and shows a "plan" of execution/deployment.
Note:- This command doesn't deploy anything, only shows what changes will be done after running "apply"
#it deploys the instructions & statements in the code
$ terraform apply
** with every "terraform apply" the "state file" is updated every time
#Apply changes without being prompted to enter "yes"
$ terraform apply --auto-approve
#Destroys all resource which is recorded inside state file
$terraform destroy
**Should be used with caution as it is non-reversible command, it is best practise to always take the backup before running this command.
#destroy/cleanup deployment without being prompted to enter "yes"
$ terraform destroy --auto-approve
#only initializes the directory but not downloads the plugin for specific provider
$ terraform init -get-plugin=false
#Shows the terraform version which is running
$ terraform version
#Download and update modules in the "root" module
$ terraform get -update=true
#pass the deployment plan to test.out
$ terraform plan -out test.out
#Outputs a destroy plan
$ terraform plan -destroy
#Only apply changes to the target resource
$ terraform apply -target=aws_instance.my_ec2
#Override a variable or pass a variable at run time
$ terraform apply -var my_region_variable=us-east-1
#Lock the remote state file (possible only where backend allows locking eg. aws s3 bucket)
$ terraform apply -lock=true
#Number of resource which can run simultaneously
$ terraform apply --parallelism=4
#Provides information of providers which is used in current configuration
$ terraform providers
#Creates a new workspace
$ terraform workspace new mytestworkspace
#Change to the selected workspace
$ terraform workspace select mytestworkspace
#List out all workspaces
$ terraform workspace list
#Show the terraform state information in human readable format
