Command: untaint

The terraform untaint command manually unmarks a Terraform-managed resource as tainted, restoring it as the primary instance in the state. This reverses either a manual terraform taint or the result of provisioners failing on a resource.

This command will not modify infrastructure, but does modify the state file in order to unmark a resource as tainted.

~> NOTE on Tainted Indexes: In certain edge cases, more than one tainted instance can be present for a single resource. When this happens, the -index flag is required to select which of the tainted instances to restore as primary. You can use the terraform show command to inspect the state and determine which index holds the instance you'd like to restore. In the vast majority of cases, there will only be one tainted instance, and the -index flag can be omitted.

Usage

Usage: terraform untaint [options] name

The name argument is the name of the resource to mark as untainted. The format of this argument is TYPE.NAME, such as aws_instance.foo.

The command-line flags are all optional (with the exception of -index in certain cases, see above note). The list of available flags are:

• -allow-missing - If specified, the command will succeed (exit code 0) even if the resource is missing. The command can still error, but only in critically erroneous cases.

• -backup=path - Path to the backup file. Defaults to -state-out with the ".backup" extension. Disabled by setting to "-".

• -index=n - Selects a single tainted instance when there are more than one tainted instances present in the state for a given resource. This flag is required when multiple tainted instances are present. The vast majority of the time, there is a maxiumum of one tainted instance per resource, so this flag can be safely omitted.

• -lock=true - Lock the state file when locking is supported.

• -lock-timeout=0s - Duration to retry a state lock.

• -module=path - The module path where the resource to untaint exists. By default this is the root path. Other modules can be specified by a period-separated list. Example: "foo" would reference the module "foo" but "foo.bar" would reference the "bar" module in the "foo" module.

• -no-color - Disables output with coloring

• -state=path - Path to read and write the state file to. Defaults to "terraform.tfstate". Ignored when remote state is used.

• -state-out=path - Path to write updated state file. By default, the -state path will be used. Ignored when remote state is used.
