## Overview

These steps remove the `inference` Helm release, its Kubernetes resources, and the external artifacts used by a model inference deployment on OpenShift. The removal process includes the following phases:

1. **Uninstall the inference release**: Uninstall the `inference` Helm release.
2. **Delete cluster resources**: Delete the `poolside-models` namespace, which removes the remaining workloads, secrets, ConfigMaps, Routes, and persistent volume claims.
3. **Clean up external artifacts**: Remove remaining artifacts such as DNS records, TLS certificates, container images, and S3 objects.

## Prerequisites

These instructions assume that you deployed model inference using [Install on OpenShift](https://docs.poolside.ai/deployment/cloud/openshift/install). Before you start, make sure you have:

- Cluster administrator access to the OpenShift cluster
- `helm` `3.12` or later
- `oc` or `kubectl`

## Step 1: Uninstall the inference release

List the Helm releases in the `poolside-models` namespace:

```
helm list -n poolside-models
```

Uninstall the inference release:

```
helm uninstall inference -n poolside-models
```

Wait for the inference pods to stop. Continue when `oc get pods -n poolside-models` shows no Poolside pods remaining:

```
oc get pods -n poolside-models
```

## Step 2: Delete cluster resources

Deleting the namespace removes the remaining workloads, secrets, ConfigMaps, Routes, and persistent volume claims that the inference stack created. Delete the `poolside-models` namespace:

```
oc delete namespace poolside-models
```

## Step 3: Clean up external artifacts

Clean up the following external resources separately. Remove only the resources that you no longer need.

**Container images**  
Delete the Poolside container images and repositories from your registry. The exact procedure depends on the registry you use.

**S3-compatible object storage**  
Delete the model checkpoints from the bucket you referenced in `models.<key>.model` in the `inference_values.yaml` file you used to install:

```
aws s3 rm s3://<bucket-name>/checkpoints --recursive --region <aws-region>
```

If you use a non-AWS S3 endpoint, add the `--endpoint-url` flag and set it to your S3 endpoint URL. If your bucket only stored Poolside data, you can delete the bucket itself.

**TLS certificates and DNS records**  
Remove the DNS records that pointed to your Route host, and revoke or delete any TLS certificates that you issued for that hostname.

**Local files**  
Delete the extracted Helm bundle directory, your `inference_values.yaml` file, and any TLS material (`tls.crt`, `tls.key`, `ca-bundle.crt`) that you kept on your workstation.
