import.string

The import.string block imports custom components from a string and exposes them to the importer. import.string blocks must be given a label that determines the namespace where custom components are exposed.

Usage

river
import.string "NAMESPACE" {
  content = CONTENT
}

Arguments

The following arguments are supported:

NameTypeDescriptionDefaultRequired
contentsecret or stringThe contents of the module to import as a secret or string.yes

content is a string that contains the configuration of the module to import. content is typically loaded by using the exports of another component. For example,

  • local.file.LABEL.content
  • remote.http.LABEL.content
  • remote.s3.LABEL.content

Example

This example imports a module from the content of a file stored in an S3 bucket and instantiates a custom component from the import that adds two numbers:

river
remote.s3 "module" {
  path = "s3://test-bucket/module.river"
}

import.string "math" {
  content = remote.s3.module.content
}

math.add "default" {
  a = 15
  b = 45
}
