CodeQL documentation

Publishing and using CodeQL packs

You can publish your own CodeQL packs and use packs published by other people.

Note

The CodeQL package management functionality, including CodeQL packs, is currently available as a beta release and is subject to change. During the beta release, CodeQL packs are available only using GitHub Packages - the GitHub Container registry. To use this beta functionality, install the latest version of the CodeQL CLI bundle from: https://github.com/github/codeql-action/releases.

Configuring the qlpack.yml file before publishing

You can check and modify the configuration details of your CodeQL pack prior to publishing. Open the qlpack.yml file in your preferred text editor.

library: # set to true if the pack is a library. Set to false or omit for a query pack
name: <scope>/<pack>
version: <x.x.x>
description: <Description to publish with the package>
default-suite: # optional, one or more queries in the pack to run by default
    - query: <relative-path>/query-file>.ql
default-suite-file: default-queries.qls # optional, a pointer to a query-suite in this pack
license: # optional, the license under which the pack is published
dependencies: # map from CodeQL pack name to version range
  • name: must follow the <scope>/<pack> format, where <scope> is the GitHub organization that you will publish to and <pack> is the name for the pack.
  • A maximum of one of default-suite or default-suite-file is allowed. These are two different ways to define a default query suite to be run, the first by specifying queries directly in the qlpack.yml file and the second by specifying a query suite in the pack.

Running codeql pack publish

When you are ready to publish a pack to the GitHub Container registry, you can run the following command in the root of the pack directory:

codeql pack publish

The published package will be displayed in the packages section of GitHub organization specified by the scope in the qlpack.yml file.

Running codeql pack download <scope>/<pack>

To run a pack that someone else has created, you must first download it by running the following command:

codeql pack download <scope>/<pack>@x.x.x
  • <scope>: the name of the GitHub organization that you will download from.
  • <pack>: the name for the pack that you want to download.
  • @x.x.x: an optional version number. If omitted, the latest version will be downloaded.

This command accepts arguments for multiple packs.

Using a CodeQL pack to analyze a CodeQL database

To analyze a CodeQL database with a CodeQL pack, run the following command:

codeql database analyze <database> <scope>/<pack>@x.x.x:<path>
  • <database>: the CodeQL database to be analyzed.
  • <scope>: the name of the GitHub organization that the pack is published to.
  • <pack>: the name for the pack that you are using.
  • @x.x.x: an optional version number. If omitted, the latest version will be used.
  • :<path>: an optional path to a query, directory, or query suite. If omitted, the pack’s default query suite will be used.

The analyze command will run the default suite of any specified CodeQL packs. You can specify multiple CodeQL packs to be used for analyzing a CodeQL database. For example:

codeql <database> analyze <scope>/<pack> <scope>/<other-pack>

Working with CodeQL packs on GitHub Enterprise Server

Note

The Container registry for GitHub Enterprise Server supports CodeQL query packs from GitHub Enterprise Server 3.6 onward.

By default, the CodeQL CLI expects to download CodeQL packs from and publish packs to the Container registry on GitHub.com. However, you can also work with CodeQL packs in a Container registry on GitHub Enterprise Server 3.6, and later, by creating a qlconfig.yml file to tell the CLI which Container registry to use for each pack.

Create a ~/.codeql/qlconfig.yml file using your preferred text editor, and add entries to specify which registry to use for one or more package name patterns. For example, the following qlconfig.yml file associates all packs with the Container registry for the GitHub Enterprise Server at GHE_HOSTNAME, except packs matching codeql/*, which are associated with the Container registry on GitHub.com:

registries:
- packages:
  - 'codeql/*'
  - 'other-org/*'
  url: https://ghcr.io/v2/
- packages: '*'
  url: https://containers.GHE_HOSTNAME/v2/

The CodeQL CLI will determine which registry to use for a given package name by finding the first item in the registries list with a packages property that matches that package name. This means that you’ll generally want to define the most specific package name patterns first. The packages property may be a single package name, a glob pattern, or a YAML list of package names and glob patterns.

The registries list can also be placed inside of a codeql-workspace.yml file. Doing so will allow you to define the registries to be used within a specific workspace, so that it can be shared amongst other CodeQL users of the workspace. The registries list in the codeql-workspace.yml will be merged with and take precedence over the list in the global qlconfig.yml. For more information about codeql-workspace.yml, see About CodeQL workspaces.

You can now use codeql pack publish, codeql pack download, and codeql database analyze to manage packs on GitHub Enterprise Server.

Authenticating to GitHub Container registries

You can publish packs and download private packs by authenticating to the appropriate GitHub Container registry.

You can authenticate to the Container registry on GitHub.com in two ways:

  1. Pass the --github-auth-stdin option to the CodeQL CLI, then supply a GitHub Apps token or personal access token via standard input.
  2. Set the GITHUB_TOKEN environment variable to a GitHub Apps token or personal access token.

Similarly, you can authenticate to a GHES Container registry, or authenticate to multiple registries simultaneously (for example, to download or run private packs from multiple registries) in two ways:

  1. Pass the --registries-auth-stdin option to the CodeQL CLI, then supply a registry authentication string via standard input.
  2. Set the CODEQL_REGISTRIES_AUTH environment variable to a registry authentication string.

A registry authentication string is a comma-separated list of <registry-url>=<token> pairs, where registry-url is a GitHub Container registry URL, such as https://containers.GHE_HOSTNAME/v2/, and token is a GitHub Apps token or personal access token for that GitHub Container registry. This ensures that each token is only passed to the Container registry you specify. For instance, the following registry authentication string specifies that the CodeQL CLI should authenticate to the Container registry on GitHub.com using the token <token1> and to the Container registry for the GHES instance at GHE_HOSTNAME using the token <token2>:

https://ghcr.io/v2/=<token1>,https://containers.GHE_HOSTNAME/v2/=<token2>
