+# Self-hosted Docker images
+
+Self-hosted Docker images can be useful for reducing the ingress costs, for accelerating image pulls, or for eliminating the dependency on Cortex's public container registry.
+
+In this guide, we'll use [ECR](https://aws.amazon.com/ecr/) as the destination container registry. When an ECR repository resides in the same region as your Cortex cluster, there are no costs incurred when pulling images.
+
+## Step 1
+
+Make sure you have the [aws](https://docs.aws.amazon.com/cli/latest/userguide/install-cliv1.html), [docker](https://docs.docker.com/get-docker/), and [skopeo](https://github.com/containers/skopeo/blob/master/install.md) utilities installed.
+
+## Step 2
+
+Export the `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY` environment variables in your current shell, or run `aws configure`. These credentials must have access to push to ECR.
+
+## Step 3
+
+Clone the Cortex repo using the release tag corresponding to your version (which you can check by running `cortex version`):
+
+<!-- CORTEX_VERSION_README -->
+
+```bash
+export CORTEX_VERSION=0.33.0
+git clone --depth 1 --branch v$CORTEX_VERSION https://github.com/cortexlabs/cortex.git
+```
+
+## Step 4
+
+Run the script below to export images to ECR in the same region and account as your cluster.
+
+Feel free to modify the script if you would like to export the images to a different registry such as a private docker hub.
+
+```bash
+./cortex/dev/export_images.sh <AWS_REGION> <AWS_ACCOUNT_ID>
+```
+
+You can now configure Cortex to use your images when creating a cluster (see [here](../management/create.md) for how to specify cluster images) and/or when deploying APIs (see the configuration docs corresponding to your API type for how to specify API images).
+
+## Cleanup
+
+You can delete your ECR images from the [AWS ECR dashboard](https://console.aws.amazon.com/ecr/repositories) (set your region in the upper right corner). Make sure all of your Cortex clusters have been deleted before deleting any ECR images.
