This allows a similar effect to pre-tainting an object but does the action within the context of a normal plan and apply, avoiding the need for an intermediate state where the old object still exists but is marked as tainted. The core functionality for this was already present, so this commit is just the UI-level changes to make that option available for use and to explain how it contributed to the resulting plan in Terraform's output.

Command: taint
The terraform taint command informs Terraform that a particular object has
become degraded or damaged. Terraform represents this by marking the
object as "tainted" in the Terraform state, in which case Terraform will
propose to replace it in the next plan you create.
~> Warning: This command is deprecated, because there are better alternatives available in Terraform v1.0 and later. See below for more details.
If your intent is to force replacement of a particular object even though
there are no configuration changes that would require it, we recommend instead
to use the -replace option with terraform apply.
For example:
terraform apply -replace="aws_instance.example[0]"
Creating a plan with the "replace" option is superior to using terraform taint
because it will allow you to see the full effect of that change before you take
any externally-visible action. When you use terraform taint to get a similar
effect, you risk someone else on your team creating a new plan against your
tainted object before you've had a chance to review the consequences of that
change yourself.
The -replace=... option to terraform apply is only available from
Terraform v1.0 onwards, so if you are using an earlier version you will need to
use terraform taint to force object replacement, while considering the
caveats described above.
Usage
Usage: terraform taint [options] address
The address argument is the address of the resource to mark as tainted.
The address is in
the resource address syntax syntax,
as shown in the output from other commands, such as:
aws_instance.fooaws_instance.bar[1]aws_instance.baz[\"key\"](quotes in resource addresses must be escaped on the command line, so that they will not be interpreted by your shell)module.foo.module.bar.aws_instance.qux
This command accepts the following options:
-
-allow-missing- If specified, the command will succeed (exit code 0) even if the resource is missing. The command might still return an error for other situations, such as if there is a problem reading or writing the state. -
-lock=false- Disables Terraform's default behavior of attempting to take a read/write lock on the state for the duration of the operation. -
-lock-timeout=DURATION- Unless locking is disabled with-lock=false, instructs Terraform to retry acquiring a lock for a period of time before returning an error. The duration syntax is a number followed by a time unit letter, such as "3s" for three seconds. -
-ignore-remote-version- When using the enhanced remote backend with Terraform Cloud, continue even if remote and local Terraform versions differ. This may result in an unusable Terraform Cloud workspace, and should be used with extreme caution.
For configurations using
the local backend only,
terraform taint also accepts the legacy options
-state, -state-out, and -backup.
