export block

is an optional configuration block used to specify an emitted value of a custom component.
export
blocks must be given a label which determine the name of the export.
The export
block may only be specified inside the definition of a declare
block.
Note
In classic modules, theexport
block is valid as a top-level block in a classic module. Classic modules are deprecated and scheduled to be removed in the release after v0.40.
Example
export "ARGUMENT_NAME" {
value = ARGUMENT_VALUE
}
Arguments
The following arguments are supported:
Name | Type | Description | Default | Required |
---|---|---|---|---|
value | any | Value to export. | yes |
The value

To expose an exported field of another component, set value
to an expression that references that exported value.
Exported fields
The export
block doesn’t export any fields.
Example
This example creates a custom component where the output of discovering Kubernetes pods and nodes are exposed to the user:
declare "pods_and_nodes" {
discovery.kubernetes "pods" {
role = "pod"
}
discovery.kubernetes "nodes" {
role = "nodes"
}
export "kubernetes_resources" {
value = concat(
discovery.kubernetes.pods.targets,
discovery.kubernetes.nodes.targets,
)
}
}
