Usage: tofu [global options] taint [options] <address>
OpenTofu uses the term "tainted" to describe a resource instance
which may not be fully functional, either because its creation
partially failed or because you've manually marked it as such using
this command.
This will not modify your infrastructure directly, but subsequent
OpenTofu plans will include actions to destroy the remote object
and create a new object to replace it.
You can remove the "taint" state from a resource instance using
the "tofu untaint" command.
The address is in the usual resource address syntax, such as:
aws_instance.foo
aws_instance.bar[1]
module.foo.module.bar.aws_instance.baz
Use your shell's quoting or escaping syntax to ensure that the
address will reach OpenTofu correctly, without any special
interpretation.
Options:
-allow-missing If specified, the command will succeed (exit code 0)
even if the resource is missing.
-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=0s Duration to retry a state lock.
-ignore-remote-version A rare option used for the remote backend only. See
the remote backend documentation for more information.
-var 'foo=bar' Set a value for one of the input variables in the root
module of the configuration. Use this option more than
once to set more than one variable.
-var-file=filename Load variable values from the given file, in addition
to the default files terraform.tfvars and *.auto.tfvars.
Use this option more than once to include more than one
variables file.
-json Produce output in a machine-readable JSON format,
suitable for use in text editor integrations and other
automated systems. Always disables color.
-json-into=out.json Produce the same output as -json, but sent directly
to the given file. This allows automation to preserve
the original human-readable output streams, while
capturing more detailed logs for machine analysis.
-state, state-out, and -backup are legacy options supported for the local
backend only. For more information, see the local backend's documentation.
