description: "How to apply a patch script to an existing Corridor installation with the patch command, without doing a full reinstall."
---

Corridor has an option to apply a patch to the existing codebase, without doing a complete new installation.
This can be done by running the command:

The follow components support this command: `corridor-api`, `corridor-app`, `corridor-worker`.

```bash
corridor-api patch <<filename.py>>
```

To check the options available for other components:

- `corridor-app`

```bash
corridor-app patch --help
```

- `corridor-worker`

```bash
corridor-worker patch --help
```

:::note
Ensure patches are provided by and run with the supervision of the Corridor team. A wrong patch applied could cause the platform to stop working.
:::

## Examples

Example of a patch being run:

```bash
$ corridor-api patch patch-v1.14.3-hello-world.py
Hello World!
```

Contents of the file `patch-v1.14.3-hello-world.py`:

```python
print('Hello World!')
```
