#  signal-resource  Â¶

##  Description  Â¶

Sends a signal to the specified resource with a success or failure status. You
can use the ` SignalResource  ` operation in conjunction with a creation
policy or update policy. CloudFormation doesnât proceed with a stack
creation or update until resources receive the required number of signals or
the timeout period is exceeded. The ` SignalResource  ` operation is useful in
cases where you want to send signals from anywhere other than an Amazon EC2
instance.

##  Options  Â¶

` --stack-name  ` (string)

> The stack name or unique stack ID that includes the resource that you want
> to signal.

` --logical-resource-id  ` (string)

> The logical ID of the resource that you want to signal. The logical ID is
> the name of the resource that given in the template.

` --unique-id  ` (string)

> A unique ID of the signal. When you signal Amazon EC2 instances or Auto
> Scaling groups, specify the instance ID that you are signaling as the unique
> ID. If you send multiple signals to a single resource (such as signaling a
> wait condition), each signal requires a different unique ID.

` --status  ` (string)

> The status of the signal, which is either success or failure. A failure
> signal causes CloudFormation to immediately fail the stack creation
