Grafana Plugin Validator

License Drone Go Report Card

This tool helps speed up the process of publishing plugins to Grafana.com. It runs a series of analyzers to ensure plugins are following best practices, checking for security and structural issues, as well as specific requirements related to publishing. A general overview of these requirements can be found here: https://grafana.com/docs/grafana/latest/developers/plugins/publishing-and-signing-criteria/.

It requires a path to a remote or local ZIP archive of the plugin to be specified, for example:

  • Remote: https://github.com/grafana/clock-panel/releases/download/v2.1.2/grafana-clock-panel-2.1.2.zip
  • Local: file://Users/me/Downloads/grafana-clock-panel-2.1.2.zip

You can additionally provide a link to the source code for the project with -sourceCodeUri to enable additional analyzers such as the Vulnerability Scan.

Installation and usage

Ensure that your version of Go matches the one specified in the go.mod file to avoid compatibility issues

Docker (recommended)

It is easiest to run the tool using the Docker image as it contains all the security scanning tools needed for the full set of analyzers - so you don't need to have these additional tools installed on your system.

docker run --pull=always grafana/plugin-validator-cli [options] [http://yourdomain/plugin_archive.zip]

Example 1 (basic)

docker run --pull=always grafana/plugin-validator-cli https://github.com/grafana/clock-panel/releases/download/v2.1.2/grafana-clock-panel-2.1.2.zip

Example 2 (specifying source code location)

docker run --pull=always grafana/plugin-validator-cli -sourceCodeUri https://github.com/grafana/clock-panel/tree/v2.1.2 https://github.com/grafana/clock-panel/releases/download/v2.1.2/grafana-clock-panel-2.1.2.zip

Using a local archive file with Docker

To run the tool with a local archive you will need to mount it as a docker volume. Here's an example:

docker run --pull=always -v /path/to/plugin_archive.zip:/archive.zip grafana/plugin-validator-cli /archive.zip

[!NOTE] If using relative paths your path must start with ./

Using a local archive file and local source code

docker run --pull=always -v /path/to/plugin_archive.zip:/archive.zip -v /path/to/source_code:/source_code grafana/plugin-validator-cli -sourceCodeUri /source_code /archive.zip

[!NOTE] If using relative paths your path must start with ./

NPX

npx -y @grafana/plugin-validator@latest -sourceCodeUri [options] [path/to/plugin_archive.zip]

Locally

First you must compile and install it:

git clone git@github.com:grafana/plugin-validator.git
cd plugin-validator/pkg/cmd/plugincheck2
go install

Then you can run the utility:

plugincheck2 -sourceCodeUri [source_code_location/] [plugin_archive.zip]

Generating local files For validation

You must create a .zip archive containing the dist/ directory but named as your plugin ID:

PLUGIN_ID=$(grep '"id"' < src/plugin.json | sed -E 's/.*"id" *: *"(.*)".*/\1/')
cp -r dist "${PLUGIN_ID}"
zip -qr "${PLUGIN_ID}.zip" "${PLUGIN_ID}"
npx @grafana/plugin-validator@latest -sourceCodeUri file://. "${PLUGIN_ID}.zip"

You can optionally remove the files that were generated:

rm -r "${PLUGIN_ID}" "${PLUGIN_ID}.zip"

Options

Additional options can be passed to the tool:

❯ plugincheck2 -help
Usage plugincheck2:
  -config string (optional)
        Path to configuration file
  -sourceCodeUri string (optional)
        URI to the source code of the plugin. If set, the source code will be downloaded and analyzed. This can be a ZIP file URL, a URL to git repository or a local file (starting with `file://`)
  -strict (optional)
        If set, plugincheck returns non-zero exit code for warnings
  -checksum string (optional)
        If set, the checksum of the plugin archive will be checked against this value. MD5 and SHA256 are supported.
  -analyzer string (optional)
        If set, only an specific analyzer and it's dependencies will run.

Using a configuration file

You can pass a configuration YAML file to the validator with the -config option. Several configuration examples are available to use here: https://github.com/grafana/plugin-validator/tree/main/config.

Enabling and disabling analyzers via config

If you want to disable an specific check (analyzer) you can define this in your configuration file, adding an analyzers section, and specifying which analyzer or analyzer rules to enable and disable.

For example, disable the version analyzer:

global:
  enabled: true
  jsonOutput: false
  reportAll: false

analyzers:
  version:
    enabled: false

You can also disable specific rules or change their severity level:

global:
  enabled: true
  jsonOutput: false
  reportAll: false

analyzers:
  readme:
    rules:
      missing-readme:
        enabled: true
        severity: warning

Severity levels could be: error, warning, or ok.

Note: Grafana Labs enforces its own configuration for plugins submissions and your own config file can't change these rules.

Source code

You can specify the location of the plugin source code to the validator with the -sourceCodeUri option. Doing so allows for additional analyzers to be run and for a more complete scan.

Supported remote Git services

The following public Git services are supported:

  • GitHub
  • GitLab
  • Bitbucket

Private repositories are not currently supported.

Make sure to include the ref (branch or tag) of the corresponding source code.

For example: you are validating version v2.1.2 and your project is in GitHub. Make sure you create a corresponding tag or branch and use the URL https://github.com/grafana/clock-panel/tree/v2.1.2.

Debug mode

You can run the validator in debug mode to get more information about the running checks and possible errors.

Docker:

docker run --pull=always -e DEBUG=1 grafana/plugin-validator-cli -sourceCodeUri https://github.com/grafana/clock-panel/tree/v2.1.2 https://github.com/grafana/clock-panel/releases/download/v2.1.2/grafana-clock-panel-2.1.2.zip

NPX:

DEBUG=1 npx -y @grafana/plugin-validator@latest -sourceCodeUri https://github.com/grafana/clock-panel/tree/v2.1.2 https://github.com/grafana/clock-panel/releases/download/v2.1.2/grafana-clock-panel-2.1.2.zip

Locally:

Security tools

This validator makes uses of the following open source security tools:

If you run the validator locally or via NPX you can benefit from installing these tools in your system to make them part of your validation checks.

Analyzers

The tool runs a series of analyzers to ensure submitted plugins are following best practices, and speed up the process of approving a plugin for publishing, detailed in the table below. The Analyzer column includes the name required for altering the behavior of a given check in a configuration file.
