Terraform: [0.12] cannot taint indexed resource: Error Attribute name required

[sjwl]

Attempting to taint a single resource from a list of resources errors with Error: Attribute name required

Terraform Version

v0.12.0-dev (compiled from master today)

Terraform Configuration Files

resource "test_resource" "multiple" {
  count = 2
  required = "foo"
  required_map = {
    foo = "bar"
  }
}

Debug Output

Crash Output

Expected Behavior

terraform taint test_resource.multiple.1
The resource test_resource.multiple.1 in the module root has been marked as tainted!

Actual Behavior

terraform taint test_resource.multiple.1

Error: Attribute name required

  on  line 1:
  (source code not available)

Dot must be followed by attribute name.

Steps to Reproduce

1. terraform init
2. terraform apply
3. terraform taint test_resource.multiple.1

Additional Context

terraform 0.11.10 works

Hi @sjwl,

Thanks for pointing this out.
The address syntax in 0.12 has been made more consistent, and indexing is now always done with the [] index operator. The proper syntax for this command would be

terraform taint test_resource.multiple[1]

I'll see if we can point this out a little better in the cli or the docs.

@jbardin interesting...here's what I get

terraform taint test_resource.multiple[1]
zsh: no matches found: test_resource.multiple[1]

But this error doesn't seem to be from terraform, so I wrap the resource in quotes

terraform taint "test_resource.multiple[1]"
Resource instance test_resource.multiple[1] has been marked as tainted.

this helped me find a better workaround with the zsh error:

added to my .zshrc

unsetopt nomatch

Ah yes, the square brackets take precedence in zsh. In bash it's not a factor, but it's usually good practice to properly quote arguments to prevent misinterpreting them.

How to taint all indexes in resource?
Let say I want taint
aws_instance.bar[*]
Is it posible?

I'm on Terraform v0.12.26 and have hit this with string indexes. I am definitely passing through the correct syntax, but TF is refusing to understand it's a string:

> echo azurerm_key_vault_secret.organization_google_credentials["something"]
azurerm_key_vault_secret.organization_google_credentials["something"]
> terraform untaint azurerm_key_vault_secret.organization_google_credentials["something"]

Error: Index value required

  on  line 1:
  (source code not available)

Index brackets must contain either a literal number or a literal string.

Any help appreciated!

Hi @kentcb

If you haven't got a solution to this already, I think you need to escape the double quotes per here: https://www.terraform.io/docs/commands/taint.html#example-tainting-a-single-resource-created-with-for_each
