Set a single cluster configuration property.

This command is provided for use in scripts. For interactive editing, or bulk changes, use the `edit` and `import` commands respectively.

You may also use `<key>=<value>` notation for setting configuration properties:

```bash
rpk cluster config set log_retention_ms=-1
```

If an empty string is given as the value, the property is reset to its default.

## [](#usage)Usage

```bash
rpk cluster config set <key> <value> [flags]
```

## [](#flags)Flags

| Value | Type | Description |
| --- | --- | --- |
| -h, --help | - | Help for set. |
| --all | - | Include all properties, including tunables. |
| --config | string | Redpanda or rpk config file; default search paths are /var/lib/redpanda/.config/rpk/rpk.yaml, $PWD/redpanda.yaml, and /etc/redpanda/redpanda.yaml. |
| -X, --config-opt | stringArray | Override rpk configuration settings. See rpk -X or execute rpk -X help for inline detail or rpk -X list for terser detail. |
| --profile | string | Profile to use. See rpk profile for more details. |
| -v, --verbose | - | Enable verbose logging. |

> 📝 **NOTE**
>
> Setting properties to non-number values (such as setting string values with `-`) can be problematic for some terminals due to how POSIX flags are parsed. For example, the following command may not work from some terminals:
>
> ```none
> rpk cluster config set delete_retention_ms -1
> ```
>
> Workaround: Use `--` to disable parsing for all subsequent characters. For example:
>
> ```none
> rpk cluster config set -- delete_retention_ms -1
> ```
