![]() ![]() ![]() ![]() Here is the configuration for how these resources are created #. I think it has something to do with how the names of the queue's are assigned, because when I try to run the configuration, it is telling me that the `name` is what is forcing the replacement and is only known after apply (even though I set it via local values?) Previously, when the configuration was applied, the SQS queues that the configuration creates were untouched, however now, with no changes to the configuration other than the syntax changes between 0.11 and 0.12, my SQS queues and the policies associated with them are destroyed and recreated. I recently went through the process of updating the version of Terraform my company is using from the very old 0.11, to the next minor version 0.12 (bringing the AWS provider from v1 to v3 in the process). aws_s3_bucket.example: Destruction complete after 1sĪpply complete !

Terraform waits until the bucket is created to begin creating the other twoīoth implicit and explicit dependencies affect the order in which resources areĬlean up the resources you created in this tutorial using Terraform. nameprefix - (Optional) Creates a unique name beginning with the specified prefix. If omitted, Terraform will assign a random name. fifo ( my-queue.fifo ) The name of any AWS SQS queue cannot be longer than 80 characters, and can only contain letters, numbers, dashes ( ), and underscores ( ). Argument Reference The following arguments are supported: name - (Optional) This is the human-readable name of the queue. Since both the instance and the SQS Queue are dependent upon the S3 Bucket, When you create anAWS FIFO SQS queue with Terraform, you may get the error message: Error: invalid queue name The name of an AWS FIFO SQS queue has to end with.

Resources in the depends_on argument, and Terraform will wait until all of You can useĭepends_on to explicitly declare the dependency. Inside the application, and thus not visible to Terraform. That expects to use a specific Amazon S3 bucket. To illustrate this, assume you have an application running on your EC2 instance Resources to create explicit dependencies for. The depends_onĪrgument is accepted by any resource or module block and accepts a list of Resources that are not visible to Terraform, however. Implicit dependencies are the primary way that Terraform understands the Terraform knows that the EC2 Instance must be created before the Elastic IP. Of all of the resources defined by the configuration. Terraform uses this dependency information to determine the correct order in In the exampleĪbove, the reference to aws_instance.example_a.id in the definition of theĪws_eip.ip block creates an implicit dependency. The resource attributes used in interpolation expressions. Terraform automatically infers when one resource depends on another by studying Was complete before creating the Elastic IP address.
