Kaspersky Container Security

Scanning images from CI/CD

To scan images from CI/CD, in the configuration file used to integrate the repository, specify the API_BASE_URL (web-address of the Kaspersky Container Security API server) and API_TOKEN (token to access API of the Kaspersky Container Security) environment variables for the scanner.

To scan an image from a TAR archive:

1. Build an image and save it as a TAR archive using any application for creating containerized images.
2. Start the scan by running a command in the following format:

   /scanner image.tar --file --stdout

   where:

   • <--file> is the file with the image to be scanned
   • <--stdout> is output to the security event log

To scan an image from a Git repository:

1. In the configuration file of the Git repository, specify the token for accessing the repository (for example, GitLab requires you to indicate a value for GITLAB_TOKEN).
2. Start scanning by running a command in the following format:

   /scanner [TARGET] [--repo REPO_URL] [--branch BRANCH] [--commit COMMIT] --stdout

   where:

   • <TARGET> is the path to the file with the image to be scanned
   • <--repo> is the web address (URL) of the Git repository
   • <--branch> is the branch of the repository to be scanned
   • <--commit> is the hash of the commit to be scanned
   • <--stdout> is the output to the security event log.
