Assuming you created a `config` as follows
08c26c477474478d971139f750984775a7f019dbe8a2e7f09d66a187c009e66d
you provide the definition for the resource as follows
terraform
resource "docker_config" "foo" {
name = "foo"
data = base64encode("{\"a\": \"b\"}")
}
then the import command is as follows
```sh
$ pulumi import docker:index/serviceConfig:ServiceConfig foo 08c26c477474478d971139f750984775a7f019dbe8a2e7f09d66a187c009e66d
```
