How to list resources when using remote state?

Question

I am using terraform 0.12.9 and state is saved on s3 bucket. I'd like to list all resources by terraform state list. Based on this document, https://www.terraform.io/docs/commands/state/list.html, it says -state=path - Path to the state file. Defaults to "terraform.tfstate". Ignored when remote state is used.. How can I pass the state file if it is on remote s3 bucket?

Answer 1

You need to configure the tfstate bucket path in your terraform.tf file:

terraform {
  backend "s3" {
    bucket = "bucket_name"
    key    = "my/key/location/terraform.tfstate"
    region = "bucket region"
  }
}

and later you need to run terraform init so that terraform would fetch the state from the remote bucket

Answer 2

1. terraform init
2. terraform workspace list # show all workspaces
3. terraform workspace select {env} # select the workspace which you want list resources
4. terraform state list # list all resources. Could return nothing if there is no resource in the workspace
5. terraform state show '{resource}' # show the attributes of a single resource
