このバージョンの GitHub Enterprise はこの日付をもって終了となります: 2022-10-12. 重大なセキュリティの問題に対してであっても、パッチリリースは作成されません。 パフォーマンスの向上、セキュリティの向上、新機能の向上を図るために、最新バージョンの GitHub Enterprise にアップグレードします。 アップグレードに関するヘルプについては、GitHub Enterprise サポートにお問い合わせください

Installing CodeQL CLI in your CI system

You can install the CodeQL CLI and use it to perform CodeQL code scanning in a third-party continuous integration system.

Code scanning is available for organization-owned repositories in GitHub Enterprise Server. This feature requires a license for GitHub Advanced Security. 詳細については、「GitHub Advanced Security について」を参照してください。

注: この機能を使用するには、サイト管理者が your GitHub Enterprise Server instance の code scanning を有効にする必要があります。 詳しくは、「アプライアンスでの code scanning の構成」をご覧ください。

About using the CodeQL CLI for code scanning

You can use the CodeQL CLI to run code scanning on code that you're processing in a third-party continuous integration (CI) system. Code scanning は、開発者が GitHub リポジトリ内のコードを分析して、セキュリティの脆弱性とコーディングエラーを見つけることができる機能です。 分析によって特定されたすべての問題はGitHub Enterprise Serverに表示されます。 For information, see "About code scanning with CodeQL." For recommended specifications (RAM, CPU cores, and disk) for running CodeQL analysis, see "Recommended hardware resources for running CodeQL."

CodeQL CLIは、コードの分析に利用できるスタンドアローンの製品です。 その主な目的は、コードベースのデータベース表現であるCodeQLデータベースを生成することです。 データベースの準備ができれば、それに対してインタラクティブにクエリを実行したり、SARIFフォーマットで結果セットを生成するためのクエリのスイートを実行して、結果をyour GitHub Enterprise Server instanceにアップロードしたりできます。

Alternatively, you can use GitHub Actions to run code scanning within GitHub Enterprise Server. For information about code scanning using actions, see "Setting up code scanning for a repository." For an overview of the options for CI systems, see "About CodeQL code scanning in your CI system".

メモ:

  • CodeQL CLI は、Advanced Security のライセンスを持つ顧客が使うことができます。

  • CodeQL CLI は現在、glibc 以外の Linux ディストリビューション ((musl ベースの) Alpine Linux など) との互換性がありません。

Downloading the CodeQL CLI

You should download the CodeQL bundle from https://github.com/github/codeql-action/releases. The bundle contains:

  • CodeQL CLI product
  • A compatible version of the queries and libraries from https://github.com/github/codeql
  • Precompiled versions of all the queries included in the bundle
For GitHub Enterprise Server 3.2, we recommend CodeQL CLI version 2.6.3.

You should always use the CodeQL bundle as this ensures compatibility and also gives much better performance than a separate download of the CodeQL CLI and checkout of the CodeQL queries. If you will only be running the CLI on one specific platform, download the appropriate codeql-bundle-PLATFORM.tar.gz file. Alternatively, you can download codeql-bundle.tar.gz, which contains the CLI for all supported platforms.

Setting up the CodeQL CLI in your CI system

You need to make the full contents of the CodeQL CLI bundle available to every CI server that you want to run CodeQL code scanning analysis on. For example, you might configure each server to copy the bundle from a central, internal location and extract it. Alternatively, you could use the REST API to get the bundle directly from GitHub, ensuring that you benefit from the latest improvements to queries. Updates to the CodeQL CLI are released every 2-3 weeks. For example:

$ wget https://HOSTNAME/github/codeql-action/releases/latest/download/codeql-bundle-linux64.tar.gz
$ tar -xvzf ./codeql-bundle-linux64.tar.gz

After you extract the CodeQL CLI bundle, you can run the codeql executable on the server:

  • By executing /<extraction-root>/codeql/codeql, where <extraction-root> is the folder where you extracted the CodeQL CLI bundle.
  • By adding /<extraction-root>/codeql to your PATH, so that you can run the executable as just codeql.

Testing the CodeQL CLI set up

After you extract the CodeQL CLI bundle, you can run the following command to verify that the CLI is correctly set up to create and analyze databases.

  • codeql resolve qlpacks if /<extraction-root>/codeql is on the PATH.
  • /<extraction-root>/codeql/codeql resolve qlpacks otherwise.

Extract from successful output:

codeql/cpp-all (/<extraction-root>/qlpacks/codeql/cpp-all/<version>)
codeql/cpp-examples (/<extraction-root>/qlpacks/codeql/cpp-examples/<version>)
codeql/cpp-queries (/<extraction-root>/qlpacks/codeql/cpp-queries/<version>)
codeql/csharp-all (/<extraction-root>/qlpacks/codeql/charp-all/<version>)
codeql/csharp-examples (/<extraction-root>/qlpacks/codeql/charp-examples/<version>)
codeql/csharp-queries (/<extraction-root>/qlpacks/codeql/charp-queries/<version>)
codeql/java-all (/<extraction-root>/qlpacks/codeql/java-all/<version>)
codeql/java-examples (/<extraction-root>/qlpacks/codeql/java-examples/<version>)
codeql/java-queries (/<extraction-root>/qlpacks/codeql/java-queries/<version>)
codeql/javascript-all (/<extraction-root>/qlpacks/codeql/javascript-all/<version>)
codeql/javascript-examples (/<extraction-root>/qlpacks/codeql/javascript-examples/<version>)
codeql/javascript-queries (/<extraction-root>/qlpacks/codeql/javascript-queries/<version>)
codeql/python-all (/<extraction-root>/qlpacks/codeql/python-all/<version>)
codeql/python-examples (/<extraction-root>/qlpacks/codeql/python-examples/<version>)
codeql/python-queries (/<extraction-root>/qlpacks/codeql/python-queries/<version>)
codeql/ruby-all (/<extraction-root>/qlpacks/codeql/ruby-all/<version>)
codeql/ruby-examples (/<extraction-root>/qlpacks/codeql/ruby-examples/<version>)
codeql/ruby-queries (/<extraction-root>/qlpacks/codeql/ruby-queries/<version>)
...

You should check that the output contains the expected languages and also that the directory location for the qlpack files is correct. The location should be within the extracted CodeQL CLI bundle, shown above as <extraction root>, unless you are using a checkout of github/codeql. If the CodeQL CLI is unable to locate the qlpacks for the expected languages, check that you downloaded the CodeQL bundle and not a standalone copy of the CodeQL CLI.

Generating a token for authentication with GitHub Enterprise Server

Each CI server needs a GitHub App or personal access token for the CodeQL CLI to use to upload results to GitHub Enterprise Server. You must use an access token or a GitHub App with the security_events write permission. If CI servers already use a token with this scope to checkout repositories from GitHub Enterprise Server, you could potentially allow the CodeQL CLI to use the same token. Otherwise, you should create a new token with the security_events write permission and add this to the CI system's secret store. For information, see "Building GitHub Apps" and "Creating a personal access token."

Next steps

You're now ready to configure the CI system to run CodeQL analysis, generate results, and upload them to GitHub Enterprise Server where the results will be matched to a branch or pull request and displayed as code scanning alerts. For detailed information, see "Configuring CodeQL CLI in your CI system."
