# Teardown / Uninstall

`helm uninstall` removes the SPAR **workloads**, but it does **not** drop the PostgreSQL database and role — those live inside the shared `commons-postgresql` instance and are not owned by the Helm release, so they survive. A subchart Job (`postgres-init`) and any retained PVs also linger. The repository ships an **uninstall script** that cleans all of this up safely.

Script: [`deployment/scripts/uninstall-spar.sh`](https://gitlab.com/openg2p/spar/spar/-/blob/develop/deployment/scripts/uninstall-spar.sh)

## What it does

In order:

1. **`helm uninstall <release>`** — SPAR workloads, services, Helm-owned secrets/configmaps, istio virtualservices/gateways, etc.
2. **Deletes leftover subchart Jobs and their Pods** (`postgres-init`).
3. **Sweeps leftover Secrets/ConfigMaps** labelled `app.kubernetes.io/instance=<release>`.
4. **Drops the Postgres database and role** for this release, by `kubectl exec` into the Postgres pod (it terminates connections, then `DROP DATABASE` / `DROP ROLE`).
5. **Deletes PVCs** labelled with the release.
6. **Deletes PVs** still bound to those PVCs (typically `Released` PVs created with `reclaimPolicy=Retain`).

### Database dropped

Only the database this chart's `postgres-init` created:

* `<release-with-underscores>` — e.g. release `spar` → database `spar`, role `spar_user`.

It does **not** drop databases owned by other components.

## What it preserves

{% hint style="danger" %}
The script **never deletes the PostgreSQL pod/instance** (`commons-postgresql`). It only `kubectl exec`s into it to drop SPAR's own database and role. Other databases and all other components are left untouched.
{% endhint %}

## Usage

```bash
cd spar/deployment/scripts

# Always dry-run first — prints the full blast radius, changes nothing:
./uninstall-spar.sh --namespace trial --dry-run

# For real (prompts you to type the release name to confirm):
./uninstall-spar.sh --namespace trial

# Non-interactive (CI / scripted):
./uninstall-spar.sh --namespace trial --yes
```

### Options

| Flag                   | Default               | Description                                       |
| ---------------------- | --------------------- | ------------------------------------------------- |
| `--namespace`, `-n`    | *(required)*          | Release namespace.                                |
| `--release`            | `spar`                | Helm release name (determines the DB/role names). |
| `--postgres-release`   | `commons-postgresql`  | Postgres Helm release to exec into.               |
| `--postgres-namespace` | same as `--namespace` | Namespace of the Postgres instance.               |
| `--keep-pvs`           | off                   | Delete PVCs but keep the PVs.                     |
| `--dry-run`            | off                   | Print actions, change nothing.                    |
| `--yes`, `-y`          | off                   | Skip the interactive confirmation.                |

Requires: `kubectl` (cluster admin), `helm`, `jq`, and `bash` 4+.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.openg2p.org/products/spar/deployment/teardown.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
