Configuring CodeQL CLI in your CI system

You can configure your continuous integration system to run the CodeQL CLI, perform CodeQL analysis, and upload the results to GitHub Enterprise Server for display as 代码扫描 alerts.

代码扫描 适用于启用了 GitHub Advanced Security 的组织拥有的仓库。 更多信息请参阅“关于 GitHub Advanced Security”。

注:站点管理员必须为 your GitHub Enterprise Server instance 启用 代码扫描,然后您才可使用此功能。 更多信息请参阅“为设备配置 代码扫描”。

About generating code scanning results with CodeQL CLI

Once you've made the CodeQL CLI available to servers in your CI system, and ensured that they can authenticate with GitHub Enterprise Server, you're ready to generate data.

You use three different commands to generate results and upload them to GitHub Enterprise Server:

  1. database create to create a CodeQL database to represent the hierarchical structure of a supported programming language in the repository.
  2. database analyze to run queries to analyze the CodeQL database and summarize the results in a SARIF file.
  3. github upload-results to upload the resulting SARIF file to GitHub Enterprise Server where the results are matched to a branch or pull request and displayed as 代码扫描 alerts.

You can display the command-line help for any command using the --help option.

注:上传 SARIF 数据以显示为 GitHub Enterprise Server 中的 代码扫描 结果适用于启用了 GitHub Advanced Security 的组织拥有的仓库。 更多信息请参阅“管理仓库的安全和分析设置”。

Creating CodeQL databases to analyze

  1. Check out the code that you want to analyze:

    • For a branch, check out the head of the branch that you want to analyze.
    • For a pull request, check out either the head commit of the pull request, or check out a GitHub-generated merge commit of the pull request.
  2. Set up the environment for the codebase, making sure that any dependencies are available. For more information, see Creating databases for non-compiled languages and Creating databases for compiled languages in the documentation for the CodeQL CLI.

  3. Find the build command, if any, for the codebase. Typically this is available in a configuration file in the CI system.

  4. Run codeql database create from the checkout root of your repository and build the codebase.

    codeql database create <database> --command<build> --language=<language-identifier>

    Note: If you use a containerized build, you need to run the CodeQL CLI inside the container where your build task takes place.

OptionRequiredUsage
<database>Specify the name and location of a directory to create for the CodeQL database. The command will fail if you try to overwrite an existing directory. If you also specify --db-cluster, this is the parent directory and a subdirectory is created for each language analyzed.
--languageSpecify the identifier for the language to create a database for, one of: cpp`, `csharp`, `go`, `java`, `javascript`, and `python (use javascript to analyze TypeScript code).
--commandRecommended. Use to specify the build command or script that invokes the build process for the codebase. Commands are run from the current folder or, where it is defined, from --source-root. Not needed for Python and JavaScript/TypeScript analysis.
--source-rootOptional. Use if you run the CLI outside the checkout root of the repository. By default, the database create command assumes that the current directory is the root directory for the source files, use this option to specify a different location.

For more information, see Creating CodeQL databases in the documentation for the CodeQL CLI.

Basic example

This example creates a CodeQL database for the repository checked out at /checkouts/example-repo. It uses the JavaScript extractor to create a hierarchical representation of the JavaScript and TypeScript code in the repository. The resulting database is stored in /codeql-dbs/example-repo.

$ codeql database create /codeql-dbs/example-repo --language=javascript \
    --source-root /checkouts/example-repo

> Initializing database at /codeql-dbs/example-repo.
> Running command [/codeql-home/codeql/javascript/tools/autobuild.cmd]
    in /checkouts/example-repo.
> [build-stdout] Single-threaded extraction.
> [build-stdout] Extracting
... 
> Finalizing database at /codeql-dbs/example-repo.
> Successfully created database at /codeql-dbs/example-repo.

Analyzing a CodeQL database

  1. Create a CodeQL database (see above).
  2. Run codeql database analyze on the database and specify which queries to use.
    codeql database analyze <database> --format=<format> \
        --output=<output>   <queries> 
OptionRequiredUsage
<database>Specify the path for the directory that contains the CodeQL database to analyze.
<packs,queries>Specify CodeQL packs or queries to run. To run the standard queries used for 代码扫描, omit this parameter. To see the other query suites included in the CodeQL CLI bundle, look in /<extraction-root>/codeql/qlpacks/codeql-<language>/codeql-suites. For information about creating your own query suite, see Creating CodeQL query suites in the documentation for the CodeQL CLI.
--formatSpecify the format for the results file generated by the command. For upload to GitHub this should be: sarifv2.1.0. For more information, see "SARIF support for 代码扫描."
--outputSpecify where to save the SARIF results file.
--threadsOptional. Use if you want to use more than one thread to run queries. The default value is 1. You can specify more threads to speed up query execution. To set the number of threads to the number of logical processors, specify 0.
--verboseOptional. Use to get more detailed information about the analysis process.

For more information, see Analyzing databases with the CodeQL CLI in the documentation for the CodeQL CLI.

Basic example

This example analyzes a CodeQL database stored at /codeql-dbs/example-repo and saves the results as a SARIF file: /temp/example-repo-js.sarif.

$ codeql database analyze /codeql-dbs/example-repo  \
    javascript-code-scanning.qls 
    --format=sarifv2.1.0 --output=/temp/example-repo-js.sarif

> Running queries.
> Compiling query plan for /codeql-home/codeql/qlpacks/
    codeql-javascript/AngularJS/DisablingSce.ql.
... 
> Shutting down query evaluator.
> Interpreting results.

Uploading results to GitHub Enterprise Server

注意:

  • SARIF upload supports a maximum of 5000 results per upload. 超过此限制的任何结果均被忽略。 如果工具产生太多结果,则应更新配置,以专注于最重要的规则或查询的结果。

  • For each upload, SARIF upload supports a maximum size of 10 MB for the gzip-compressed SARIF file. Any uploads over this limit will be rejected. If your SARIF file is too large because it contains too many results, you should update the configuration to focus on results for the most important rules or queries.

Before you can upload results to GitHub Enterprise Server, you must determine the best way to pass the GitHub 应用程序 or personal access token you created earlier to the CodeQL CLI (see Installing CodeQL CLI in your CI system). We recommend that you review your CI system's guidance on the secure use of a secret store. The CodeQL CLI supports:

  • Passing the token to the CLI via standard input using the --github-auth-stdin option (recommended).
  • Saving the secret in the environment variable GITHUB_TOKEN and running the CLI without including the --github-auth-stdin option.

When you have decided on the most secure and reliable method for your CI server, run codeql github upload-results on each SARIF results file and include --github-auth-stdin unless the token is available in the environment variable GITHUB_TOKEN.

echo "$UPLOAD_TOKEN" | codeql github upload-results --repository=<repository-name> \
      --ref=<ref> --commit=<commit> --sarif=<file> \
      --github-url=<URL> --github-auth-stdin
OptionRequiredUsage
--repositorySpecify the OWNER/NAME of the repository to upload data to. The owner must be an organization within an enterprise that has a license for GitHub Advanced Security and GitHub Advanced Security must be enabled for the repository. For more information, see "Managing security and analysis settings for your repository."
--refSpecify the name of the ref you checked out and analyzed so that the results can be matched to the correct code. For a branch use: refs/heads/BRANCH-NAME, for the head commit of a pull request use refs/pulls/NUMBER/head, or for the GitHub-generated merge commit of a pull request use refs/pulls/NUMBER/merge.
--commitSpecify the full SHA of the commit you analyzed.
--sarifSpecify the SARIF file to load.
--github-urlSpecify the URL for GitHub Enterprise Server.
--github-auth-stdinOptional. Use to pass the CLI the GitHub 应用程序 or personal access token created for authentication with GitHub's REST API via standard input. This is not needed if the command has access to a GITHUB_TOKEN environment variable set with this token.

For more information, see github upload-results in the documentation for the CodeQL CLI.

Basic example

This example uploads results from the SARIF file temp/example-repo-js.sarif to the repository my-org/example-repo. It tells the 代码扫描 API that the results are for the commit deb275d2d5fe9a522a0b7bd8b6b6a1c939552718 on the main branch.

$ echo $UPLOAD_TOKEN | codeql github upload-results --repository=my-org/example-repo \
    --ref=refs/heads/main --commit=deb275d2d5fe9a522a0b7bd8b6b6a1c939552718 \
    --sarif=/temp/example-repo-js.sarif --github-url=https://github.example.com \
    --github-auth-stdin

There is no output from this command unless the upload was unsuccessful. The command prompt returns when the upload is complete and data processing has begun. On smaller codebases, you should be able to explore the 代码扫描 alerts in GitHub Enterprise Server shortly afterward. You can see alerts directly in the pull request or on the Security tab for branches, depending on the code you checked out. For more information, see "Triaging 代码扫描 alerts in pull requests" and "Managing 代码扫描 alerts for your repository."
