Detecting Kubernetes configuration files using a broker

If you are using a privately hosted Git repository then you can use the Snyk Broker to connect Snyk to it. See the full broker documentation for setup. The following details additional configuration required for the Kubernetes configuration and Helm files.

Writing the configuration

The Kubernetes scanning features need access to the YAML or JSON files from the repository. This requires specific API permissions. These API permissions are slightly different depending on which source control system you are using. In the accept.json file described in the broker documentation add the following:

Configuring the broker

 The broker takes the path to the accept.json file (with the rules above added) in the ACCEPT environment variable. You can see an example of passing that to the GitHub broker below.

docker run --restart=always \
  -p 8000:8000 \
  -e BROKER_TOKEN=secret-broker-token \
  -e GITHUB_TOKEN=secret-github-token \
  -e PORT=8000 \
  -e BROKER_CLIENT_URL=https://my.broker.client:8000 \
  -e ACCEPT=/private/accept.json
  -v /local/path/to/private:/private \
  snyk/broker:github-com

Note that this gives Snyk the ability to query for any .yaml, .yml or .json files. If you would prefer to be stricter you can alter the paths in the examples above to be more restrictive to certain projects or file layouts.
