I would like to run terraform only for a specific resource

It takes a long time to run terraform and wait. So I would like to run it to exclude rds that takes the longest time to excute or I would like to run only ec2 resource. Is there a way to do such things in terraform?

I'm using Windows Powershell.
I use Double Hyphen in prefix of target (--target).

terraform apply --target=aws_s3_object.resource_name

if you want to apply changes to a specific resource or to resources within a specific module without affecting the rest of the managed resources, you can use -target terraform apply -target

For example, running

terraform apply -target=aws_instance.env0-instance will apply changes only to the resource named env0-instance of the type aws_instance

This may not be a definitive solution, but this tool could be useful.

The tool "tftarget" is designed to selectively execute "terraform xxx -target={...}".

The selection screen includes options such as "select all," so you should be able to achieve an "inverse target" effect by first selecting all resources and then deselecting the unnecessary ones.

Adding to Julio's answer, you could target multiple resources in the following manner:

terraform init
terraform plan -target=resource_type1.resource_name1 -target=resource_type2.resource_name1
terraform apply -target=resource_type1.resource_name1 -target=resource_type2.resource_name1

If you output the plan then you only need to specify the parameters during the plan phase:

terraform init
terraform plan \
  -target=resource_type1.resource_name1 \
  -target=resource_type2.resource_name1 \
  -out plan
terraform apply plan

Most of the answers not working for my terraform version v=1.0.7. This syntax works for me:

terraform plan -target aws_resource.resource_name
terraform apply -target aws_resource.resource_name

You can use -target=resource like this:

terraform plan -target=module.mymodule.aws_instance.myinstance
terraform apply -target=module.mymodule.aws_instance.myinstance

or

terraform plan -target=aws_instance.myinstance
terraform apply -target=aws_instance.myinstance

Disclaimer: Before downvoting the answer, please note that they actually asked to either "exclude" or "run only ec2 resource". And after all this time the exclude feature request is still open in the terraform repo.

For those who use variables

terraform plan -var-file dev.tfvars -target=module.mymodule.aws_instance.myinstance
terraform apply -var-file dev.tfvars -target=module.mymodule.aws_instance.myinstance

Terraform currently does not support exclusion of resources (aka. inverse targeting).

Issue #2253: "feature request: inverse targeting / exclude"

(Thanks for the link Julio Daniel Reyes.)
