Because outputs are the only supported way for users to get information about resources configured by the module. We need to add outputs to our module in theoutputs.tffile inside the module directory. A module's
Argument Reference The following arguments are supported: Global params name- (Optional) The kubernetes cluster's name. It is unique in one Alicloud account. zone_ids- (Optional, Available since v1.243.0) The IDs of the zone in which the cluster control plane is deployed. ACK automatically ...
For example, if the./app-clustermodule referenced in the example above exported an output value namedinstance_idsthen the calling module can reference that result using the expressionmodule.servers.instance_ids: resource"aws_elb""example"{# ...instances=module.servers.instance_ids} ...
In the next section, you will correct this dependency graph error. Youraws_security_groupresources reference one another in theirsecurity_groupsattributes. AWS cannot create the security groups because their configurations each reference the other group, which would not exist yet. ...
This can help you track which resources in the Terraform configuration file require a certain dependency. 22. What do you mean by a Terraform Directory? Terraform directory houses all the configuration files in Terraform, such as main.tf, variables.tf, output.tf, etc. To initialize a Terraform...
When Terraform created this EC2 instance, it also gathered the resource's metadata from the AWS provider and wrote the metadata to the state file. In later tutorials, you will modify your configuration to reference these values to configure other resources and output values. Manually Managing State...
vpc_id- (Optional, ForceNew) The VPC to which the ENI of the multicast source belongs. This field is mandatory for VPCs that is owned by another accounts. Attributes Reference The following attributes are exported: id- Thekeyof the resource supplied above.The value is formulated as<transit_ro...
Use underscores to separate multiple words in names. Wrap the resource type and name in double quotes in your resource definition. Let your code build on itself: define dependent resources after the resources that reference them. Include a type and description for every variable. ...
To reference a trigger in lifecycle and ignore_changes meta-arguments and avoid executing the configuration on subsequent Terraform apply operations, reference the trigger as follows: resource "null_resource" "exampleB" { depends_on = [null_resource.exampleA] triggers = { os_user = var.os_...
Though any Terraform configuration file in a folder is a module to see what modules are really capable of, we have to use one module from another module. We'll break themain.tfintomain.tf,variables.tf, andoutputs.tf: main.tf: data "aws_availability_zones" "all" {} ...
