CodeQL comes with a built-in package manager that helps you share and manage custom queries. Last year, we announced the public beta of CodeQL packaging — including direct integration into GitHub code scanning. This makes it easier to roll out custom queries to your repositories and gives you full control over exactly which queries are run.
This functionality will soon be released for users of GitHub Enterprise Server (GHES): it will be available with GHES 3.7. This release also includes support for using packs that are published to GitHub Container Registries (GHCR) hosted on GHES.
How do I use CodeQL query packs in code scanning?
To use CodeQL query packs in code scanning, specify a with: packs: entry in the uses: github/codeql-action/init@v2 section of your code scanning workflow. By default code scanning downloads packs the from GHCR on GitHub.com, so if you want to run one of the standard CodeQL query packs or any other public CodeQL query pack, then simply include the pack scope/name and version requirements here. You can find the full documentation here.
If you want to run packs from the GHCR on GHES, then you need to tell code scanning how to access and authenticate to the appropriate registry. For an example of how to do this in your code scanning workflow, see Downloading CodeQL packs from GitHub Enterprise Server in the GitHub documentation.
How do I publish my own CodeQL packs?
You can publish you own CodeQL packs using the CodeQL CLI. By default, the CodeQL CLI publishes packs to the GHCR on GitHub.com. If you want to publish packs to the GHCR associated with your instance of GHES, you need to tell the CodeQL CLI how to access and authenticate to the registry you want to work with. For a full example of how to specify these details, see Working with CodeQL packs on GitHub Enterprise Server in the CodeQL CLI documentation.
