+
+The `keepers` parameter in `random_id` takes a map of values that cause the random id to be regenerated.
+By tying it to attributes that might change, it makes sure the random id changes too.
+
+To make sure the node pool keeps its old name, figure out what the suffix was by running `terraform show`:
+
+```
+google_container_node_pool.example:
+  ...
+  name = example-np-20180329213336514500000001
+```
+
+Determine the base64 encoding of that value by running [this script](https://play.golang.org/p/9KrkDoxRTOw).
+Then, import that suffix as the value of `random_id`:
+
+```
+terraform import random_id.np example-np-,ELFZ1rbrAThoeQE
+```
