export block
export
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.
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
argument determines what the value of the export is.
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 = array.concat(
discovery.kubernetes.pods.targets,
discovery.kubernetes.nodes.targets,
)
}
}
