# 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.
|
||
|
|
|
||
|
|
* `-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".
|
||
|
|
|
||
|
|
* `-state-out=path` - Path to write updated state file. By default, the
|
||
|
|
`-state` path will be used.
