page_title: 'Command: untaint'
description: |-
The `opentf untaint` command tells OpenTF that an object is functioning
correctly, even though its creation failed or it was previously manually
marked as degraded.
---
# Command: untaint
OpenTF has a marker called "tainted" which it uses to track that an object
might be damaged and so a future OpenTF plan ought to replace it.
OpenTF automatically marks an object as "tainted" if an error occurs during
a multi-step "create" action, because OpenTF can't be sure that the object
was left in a fully-functional state.
You can also manually mark an object as "tainted" using the deprecated command
[`opentf taint`](/opentf/cli/commands/taint), although we no longer recommend that
workflow.
If OpenTF currently considers a particular object as tainted but you've
determined that it's actually functioning correctly and need _not_ be replaced,
you can use `opentf untaint` to remove the taint marker from that object.
This command _will not_ modify any real remote objects, but will modify the
state in order to remove the tainted status.
If you remove the taint marker from an object but then later discover that it
was degraded after all, you can create and apply a plan to replace it without
first re-tainting the object, by using a command like the following:
```
opentf apply -replace="aws_instance.example[0]"
```
## Usage
Usage: `opentf untaint [options] address`
The `address` argument is a [resource address](/opentf/cli/state/resource-addressing)
identifying a particular resource instance which is currently tainted.
This command also 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` - Don't hold a state lock during the operation. This is
dangerous if others might concurrently run commands against the same
workspace.
- `-lock-timeout=DURATION` - Unless locking is disabled with `-lock=false`,
instructs OpenTF 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.
- `-no-color` - Disables terminal formatting sequences in the output. Use this
if you are running OpenTF in a context where its output will be
rendered by a system that cannot interpret terminal formatting.
For configurations using the [`cloud` backend](/opentf/cli/cloud) or the [`remote` backend](/opentf/language/settings/backends/remote)
only, `opentf untaint`
also accepts the option
[`-ignore-remote-version`](/opentf/cli/cloud/command-line-arguments#ignore-remote-version).
For configurations using
[the `local` backend](/opentf/language/settings/backends/local) only,
`opentf untaint` also accepts the legacy options
[`-state`, `-state-out`, and `-backup`](/opentf/language/settings/backends/local#command-line-arguments).
