Dependency Scanning Analyzers (ULTIMATE)
Dependency Scanning relies on underlying third party tools that are wrapped into what we call "Analyzers". An analyzer is a dedicated project that wraps a particular tool to:
- Expose its detection logic.
- Handle its execution.
- Convert its output to the common format.
This is achieved by implementing the common API.
Dependency Scanning supports the following official analyzers:
The analyzers are published as Docker images that Dependency Scanning will use to launch dedicated containers for each analysis.
Dependency Scanning is pre-configured with a set of default images that are maintained by GitLab, but users can also integrate their own custom images.
Official default analyzers
Any custom change to the official analyzers can be achieved by using an
environment variable in your
Using a custom Docker mirror
You can switch to a custom Docker registry that provides the official analyzer
images under a different prefix. For instance, the following instructs Dependency
Scanning to pull
include: template: Dependency-Scanning.gitlab-ci.yml variables: DS_ANALYZER_IMAGE_PREFIX: my-docker-registry/gl-images
This configuration requires that your custom registry provides images for all the official analyzers.
Selecting specific analyzers
You can select the official analyzers you want to run. Here's how to enable
gemnasium while disabling all the other default ones.
include: template: Dependency-Scanning.gitlab-ci.yml variables: DS_DEFAULT_ANALYZERS: "bundler-audit,gemnasium"
bundler-audit runs first. When merging the reports, Dependency Scanning will
remove the duplicates and will keep the
Disabling default analyzers
DS_DEFAULT_ANALYZERS to an empty string will disable all the official
default analyzers. In
include: template: Dependency-Scanning.gitlab-ci.yml variables: DS_DEFAULT_ANALYZERS: ""
That's needed when one totally relies on custom analyzers.
You can provide your own analyzers as a comma separated list of Docker images.
Here's how to add
analyzers/perl to the default images.
include: template: Dependency-Scanning.gitlab-ci.yml variables: DS_ANALYZER_IMAGES: "my-docker-registry/analyzers/nugget,amy-docker-registry/nalyzers/perl"
The values must be the full path to the container registry images,
like what you would feed to the
docker pull command.
NOTE: Note: This configuration doesn't benefit from the integrated detection step. Dependency Scanning has to fetch and spawn each Docker image to establish whether the custom analyzer can scan the source code.
The following table lists the data available for each official analyzer.
|Property \ Tool||Gemnasium||bundler-audit||Retire.js|
|External ID (e.g., CVE)||✓||✓|
|Affected item (e.g. class or package)||✓||✓||✓|
|Source code extract||𐄂||𐄂||𐄂|
- ✓ => we have that data
⚠=> we have that data but it's partially reliable, or we need to extract that data from unstructured content
- 𐄂 => we don't have that data or it would need to develop specific or inefficient/unreliable logic to obtain it.
The values provided by these tools are heterogeneous so they are sometimes
normalized into common values (e.g.,
