+## Question
+
+How can we swap out machine images (e.g. tweak an AMI)?
+
+## Answer
+
+Inside the `kops` manifest,  the base images are parameterized with an environment variable `KOPS_BASE_IMAGE`.
+
+An example is provided [here](https://github.com/cloudposse/geodesic/blob/master/rootfs/templates/kops/default.yaml#L150).
+
+More information is provided [here](https://github.com/kubernetes/kops/blob/master/docs/images.md).
