# Sign a plugin
|
|
|
|
Signing a plugin allows Grafana to verify the authenticity of the plugin with [signature verification]({{< relref "../../plugins/plugin-signatures.md" >}}). This gives users a way to make sure plugins haven't been tampered with. All Grafana Labs-authored backend plugins, including Enterprise plugins, are signed.
|
|
|
|
> **Important:** Future versions of Grafana will require all plugins to be signed.
|
|
|
|
Before you can sign your plugin, you need to decide whether you want to sign it as a _public_ or a _private_ plugin.
|
|
|
|
If you want to make your plugin publicly available outside of your organization, you need to sign your plugin under a _community_ or _commercial_ [signature level](#plugin-signature-levels). Public plugins are available from [grafana.com/plugins](https://grafana.com/plugins) and can be installed by anyone.
|
|
|
|
For more information on how to install public plugin, refer to [Install Grafana plugins]({{< relref "../../plugins/installation.md" >}}).
|
|
|
|
If you intend to only use the plugin within your organization, you can to sign it under a _private_ [signature level](#plugin-signature-levels).
|
|
|
|
## Generate an API key
|
|
|
|
To verify ownership of your plugin, you need to generate an API key that you'll use every time you need to sign a new version of your plugin.
|
|
|
|
1. [Create a Grafana Cloud account](https://grafana.com/signup).
|
|
|
|
1. Make sure that the first part of the plugin ID matches the slug of your Grafana Cloud account.
|
|
|
|
You can find the plugin ID in the `plugin.json` file inside your plugin directory. For example, if your account slug is `acmecorp`, you need to prefix the plugin ID with `acmecorp-`.
|
|
|
|
1. [Create a Grafana Cloud API key](https://grafana.com/docs/grafana-cloud/cloud-portal/create-api-key/) with the **PluginPublisher** role.
|
|
|
|
## Sign a public plugin
|
|
|
|
Public plugins need to be reviewed by the Grafana team before you can sign them.
|
|
|
|
1. Submit your plugin for review by creating a pull request in the [grafana-plugin-repository](https://github.com/grafana/grafana-plugin-repository).
|
|
1. When your plugin is approved, you're granted a plugin signature level. **Without a plugin signature level, you won't be able to sign your plugin**.
|
|
1. In your plugin directory, sign the plugin with the API key you just created. Grafana Toolkit creates a [MANIFEST.txt](#plugin-manifest) file in the `dist` directory of your plugin.
|
|
|
|
```bash
|
|
export GRAFANA_API_KEY=<YOUR_API_KEY>
|
|
npx @grafana/toolkit plugin:sign
|
|
```
|
|
|
|
## Sign a private plugin
|
|
|
|
1. In your plugin directory, sign the plugin with the API key you just created. Grafana Toolkit creates a [MANIFEST.txt](#plugin-manifest) file in the `dist` directory of your plugin.
|
|
|
|
The `rootUrls` flag accepts a comma-separated list of URLs to the Grafana instances where you intend to install the plugin.
|
|
|
|
```bash
|
|
export GRAFANA_API_KEY=<YOUR_API_KEY>
|
|
npx @grafana/toolkit plugin:sign --rootUrls https://example.com/grafana
|
|
```
|
|
|
|
## Plugin signature levels
|
|
|
|
To sign a plugin, you need to decide the _signature level_ you want to sign it under. The signature level of your plugin determines how you can distribute it.
|
|
|
|
You can sign your plugin under three different _signature levels_.
|
|
|
|
| **Plugin Level** | **Paid Subscription Required?** | **Description** |
|
|
|------------------|-------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
|
|
| Private | No;<br>Free of charge | <p>You can create and sign a Private Plugin for any technology at no charge.</p><p>Private Plugins are for use on your own Grafana. They may not be distributed to the Grafana community, and are not published in the Grafana catalog.</p> |
|
|
| Community | No;<br>Free of charge | <p>You can create, sign and distribute plugins at no charge, provided that all dependent technologies are open source and not for profit.</p><p>Community Plugins are published in the official Grafana catalog, and are available to the Grafana community.</p> |
|
|
| Commercial | Yes;<br>Commercial Plugin Subscription required | <p>You can create, sign and distribute plugins with dependent technologies that are closed source or commercially backed, by entering into a Commercial Plugin Subscription with Grafana Labs.</p><p>Commercial Plugins are published on the official Grafana catalog, and are available to the Grafana community.</p> |
|
|
|
|
For instructions on how to sign a plugin under the Community and Commercial signature level, refer to [Sign a public plugin](#sign-a-public-plugin).
|
|
|
|
For instructions on how to sign a plugin under the Private signature level, refer to [Sign a private plugin](#sign-a-private-plugin).
|
|
|
|
## Plugin manifest
|
|
|
|
For Grafana to verify the digital signature of a plugin, the plugin must include a signed manifest file, _MANIFEST.txt_. The signed manifest file contains two sections:
|
|
|
|
- **Signed message -** The signed message contains plugin metadata and plugin files with their respective checksums (SHA256).
|
|
- **Digital signature -** The digital signature is created by encrypting the signed message using a private key. Grafana has a public key built-in that can be used to verify that the digital signature have been encrypted using expected private key.
|
|
|
|
**Example manifest file:**
|
|
|
|
```txt

## Troubleshooting issues while signing your plugin
|
|
|
|
### Why am I getting a "Modified signature" in Grafana?
|
|
|
|
Due to an issue when signing the plugin on Windows, grafana-toolkit generates an invalid MANIFEST.txt. You can fix this by replacing all double backslashes, `\\`, with a forward slash, `/` in the MANIFEST.txt file. You need to do this every time you sign your plugin.
|
|
|
|
### Error signing manifest: Field is required: rootUrls
|
|
|
|
If you're trying to sign a **public** plugin, this means that your plugin doesn't have a plugin signature level assigned to it yet. A Grafana team member will assign a signature level to your plugin once it has been reviewed and approved. For more information, refer to [Sign a public plugin](#sign-a-public-plugin).
|
|
|
|
If you're trying to sign a **private** plugin, this means that you need to add a `rootUrls` flag to the `plugin:sign` command. The `rootUrls` must match the [root_url]({{< relref "../../administration/configuration.md#root_url" >}}) configuration. For more information, refer to [Sign a private plugin](#sign-a-private-plugin).
|
|
|
|
If you still get this error, make sure that the API key was generated by a Grafana Cloud account that matches the first part of the plugin ID.
