Please 92 see the documentation online for resource addresses. The ID is a 93 resource-specific ID to identify that resource being imported. Please 94 reference the documentation for the resource type you're importing to 95 determine the ID syntax to use. It typically matches directly to the ID 96 that the provider uses. 97 98 In the current state of Terraform import, the resource is only imported 99 into your state file. Once it is imported, you must manually write 100 configuration for the new resource or Terraform will mark it for destruction. 101 Future versions of Terraform will expand the functionality of Terraform 102 import. 103 104 This command will not modify your infrastructure, but it will make 105 network requests to inspect parts of your infrastructure relevant to 106 the resource being imported. 107 108 Options: 109 110 -backup=path Path to backup the existing state file before 111 modifying. Defaults to the "-state-out" path with 112 ".backup" extension. Set to "-" to disable backup. 113 114 -input=true Ask for input for variables if not directly set. 115 116 -no-color If specified, output won't contain any color. 117 118 -state=path Path to read and save state (unless state-out 119 is specified). Defaults to "terraform.tfstate". 120 121 -state-out=path Path to write updated state file. By default, the 122 "-state" path will be used. 123 124 ` 125 return strings.TrimSpace(helpText) 126 } 127 128 func (c *ImportCommand) Synopsis() string { 129 return "Import existing infrastructure into Terraform" 130 }
