Command: taint

The terraform taint command manually marks a Terraform-managed resource as tainted, forcing it to be destroyed and recreated on the next apply.

This command will not modify infrastructure, but does modify the state file in order to mark a resource as tainted. Once a resource is marked as tainted, the next plan will show that the resource will be destroyed and recreated and the next apply will implement this change.

Forcing the recreation of a resource is useful when you want a certain side effect of recreation that is not visible in the attributes of a resource. For example: re-running provisioners will cause the node to be different or rebooting the machine from a base image will cause new startup scripts to run.

Note that tainting a resource for recreation may affect resources that depend on the newly tainted resource. For example, a DNS resource that uses the IP address of a server may need to be modified to reflect the potentially new IP address of a tainted server. The plan command will show this if this is the case.

Usage

Usage: terraform taint [options] name

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

The command-line flags are all optional. 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 "-".

• -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 taint 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.

Example: Tainting a Single Resource

This example will taint a single resource:

$ terraform taint aws_security_group.allow_all
The resource aws_security_group.allow_all in the module root has been marked as tainted!

Example: Tainting a Resource within a Module

This example will only taint a resource within a module:

$ terraform taint -module=couchbase aws_instance.cb_node.9
The resource aws_instance.couchbase.11 in the module root.couchbase has been marked as tainted!
